See Figure 1-2. 1 Turn on the oscilloscope. Use only power cords designed for your oscilloscope. Use a power source that delivers 100 to 240 VAC, 47 Hz to 440 Hz. Wait until the display shows that all self-tests passed. Push the Save/Recall button, select Setups in the top menu box and push the Default Setup menu box. Figure 1-2 Save/Recall button Front Panel Controls WARNING To avoid electric shock, be sure the oscilloscope is properly grounded. 2 Input a waveform to a channel of the oscilloscope. 3 Press the Autoscale button and observe the signal on the display. 1-5 Getting Started Performing a Functional Check CAUTION ! To avoid damage to the oscilloscope, make sure that the input voltage at the BNC connector does not exceed the maximum voltage (300 Vrms maximum). 1-6 Getting Started Compensating Probes Compensating Probes Perform this adjustment to match your probe to the input channel. This should be done whenever you attach a probe for the first time to any input channel. Low Frequency Compensation 1 Set the Probe menu attenuation to 10X. Press the appropriate channel button on the front panel (1 or 2), then select the Probe menu item until 10X appears. 2 Attach the probe tip to the probe compensation connector and the ground lead to the probe compensator ground connector. If you use the probe hook-tip, ensure a proper connection by firmly inserting the tip onto the probe. 3 Press the Autoscale front panel button. Figure 1-3 Low frequency compensation adjustment Correctly Compensated Over Compensated Under Compensated Probe Compensation 4 If the waveform does not appear like the Correctly Compensated waveform shown in Figure 1-3, then use a nonmetallic tool to adjust the low frequency compensation adjustment on the probe for the flattest square wave possible. High Frequency Compensation 1 Using the BNC adapter, connect the probe to a square wave generator. 1-7 Getting Started Compensating Probes 2 Set the square wave generator to a frequency of 1 MHz and an amplitude of 1 Vp-p. 3 Press the Autoscale front panel button. Figure 1-4 High frequency compensation adjustments Correctly Compensated Over Compensated Under Compensated Probe Compensation 4 If the waveform does not appear like the Correctly Compensated waveform shown in Figure 1-4, then use a nonmetallic tool to adjust the 2 high frequency compensation adjustments on the probe for the flattest square wave possible. 1-8 Getting Started Front Panel and User Interface Descriptions Front Panel and User Interface Descriptions One of the first things you will want to do with your new oscilloscope is to become acquainted with its front panel. The front panel has knobs and buttons. The knobs are used most often and are similar to the knobs on other oscilloscopes. 1-9 Getting Started Front Panel and User Interface Descriptions Figure 1-5 Vertical controls MENU ON/OFF Measure controls Horizontal controls Waveform controls Run controls Entry knob Menu defined buttons { Trigger controls Menu controls Front Panel Measure controls Waveform controls Menu controls Vertical controls Horizontal controls Trigger controls Run controls MENU ON/OFF Menu defined buttons The definitions of the buttons and the knobs are as follows: Meas and Cursors Acquire and Display Save/Recall and Utility Vertical position knobs, vertical scale knobs, 1, 2, Math and Ref menus Position knob, Main/Delayed, and scale knob Trigger level knob, 50%, Mode/Coupling, and Force Run/Stop, Autoscale, and Single Displays or hides the current menu Five gray buttons from top to bottom on the right-hand side of the screen, which select the adjacent menu items in the currently displayed menu. Pressing any of these when no menu is displayed activates the most recently displayed menu. For the adjustment defined controls Entry knob 1-10 Getting Started Front Panel and User Interface Descriptions Figure 1-6 Waveform window position in memory Trigger position in memory Trigger position in waveform window Acquisition Status Menu Waveform Channel 1 Ground Symbol Channel 1 Status User Interface Timebase Status Sample Rate 1-11 Getting Started Automatically Displaying a Waveform Automatically Displaying a Waveform The oscilloscope has an Autoscale feature that automatically sets up the oscilloscope to best display the input waveform. Using Autoscale requires waveforms with a frequency greater than or equal to 50 Hz and a duty cycle greater than 1%. When you press the Autoscale button, the oscilloscope turns on and scales all channels that have waveforms applied, and selects a time base range based on the trigger source. The trigger source selected is the lowest numbered channel that has a waveform applied. The 3000 Series Oscilloscopes are two channel oscilloscopes with an external trigger input. 1-12 Getting Started Cleaning the Oscilloscope Cleaning the Oscilloscope • Clean the oscilloscope with a soft cloth dampened with a mild soap and water solution. CAUTION Do not use too much liquid in cleaning the oscilloscope. Water can enter the oscilloscope’s front panel, damaging sensitive electronic components. 1-13 1-14 2 Using the Oscilloscope Using the Oscilloscope This chapter describes the oscilloscope’s buttons, knobs, and menus. It is recommended that you perform all of the exercises in this chapter to become familiar with the powerful measurement capabilities of the oscilloscope. 2-2 Vertical Controls Each channel has a vertical controls menu that appears after pressing either the 1 or the 2 front panel button. This section of the manual describes the vertical channel controls. 2-3 Vertical Controls Vertical System Setup Vertical System Setup Figure 2-1 shows the vertical system controls. Figure 2-1 Scale knob Position knob Vertical Controls The following exercise guides you through the vertical buttons, knobs, and status bar. 1 Center the waveform on the display using the position knob. The position knob moves the waveform vertically. Notice that as you turn the position knob, a voltage value is displayed for a short time indicating how far the ground reference is from the center of the screen. Also notice that the ground symbol on the left side of the display moves in conjunction with the position knob. Measurement hints If the channel is DC coupled, you can quickly measure the DC component of the waveform by simply noting its distance from the ground symbol. If the channel is AC coupled, the DC component of the waveform is blocked, allowing you to use greater sensitivity to display the AC component of the waveform. 2-4 Vertical Controls Vertical System Setup 2 Notice that changing the vertical setup also affects the status bar. You can quickly determine the vertical setup from the status bar in the display. a Change the vertical sensitivity with the scale knob and notice that it causes the status bar to change. b Press the 1 button. The CH1 menu appears and the channel is turned on. c Toggle each of the menu buttons and notice which buttons cause the status bar to change. d Press the 1 button to turn the channel off or on. Press the MENU ON/OFF button to hide the menu without turning the channel off. Pressing the channel’s vertical scale knob toggles its sensitivity between coarse and fine modes. In the coarse mode, the knob changes the Volts/Div scale in a 1-2-5 sequence from 2mV/div, 5mV/div, 10mV, ..., to 5 V/div. In the fine mode, the knob changes the Volts/Div scale in small steps between the coarse settings. It is helpful when you need to adjust the waveform's vertical size in finer steps. 2-5 Vertical Controls Channel Coupling Control Channel Coupling Control The channel coupling control can be used to remove any DC offset voltage on a waveform. By setting the coupling control to AC the DC offset voltage is removed form the input waveform. To remove any DC offset voltage from a waveform on channel 1, press the 1 front panel key. Press the Coupling menu key until AC appears. See Figure 2-2. Figure 2-2 AC Coupling AC Coupling Status AC Coupling Control When DC coupling is selected, both AC and DC components of the input waveform are passed to the oscilloscope. See Figure 2-3. 2-6 Vertical Controls Channel Coupling Control Figure 2-3 DC Coupling DC Coupling Status DC Coupling Control 2-7 Vertical Controls Channel Coupling Control When GND coupling is selected, the waveform is disconnected from the oscilloscope input. See Figure 2-4. Figure 2-4 Ground Coupling Ground Coupling Status GND Coupling Control 2-8 Vertical Controls Bandwidth Limit Control Bandwidth Limit Control The bandwidth limit control can be used to remove high frequency components on a waveform that are not important to the analysis of the waveform. To remove high frequency components from a waveform on channel 1, press the 1 front panel key. Press the BW Limit menu key until ON appears. Frequencies above 20 MHz will be rejected. See Figure 2-5. Figure 2-5 20 MHz Bandwidth Bandwidth Limit ON Status BW Limit Control ON When the BW Limit control is set to OFF, the oscilloscope is set to full bandwidth. See Figure 2-6. 2-9 Vertical Controls Bandwidth Limit Control Figure 2-6 Bandwidth limit OFF BW Limit Control OFF 2-10 Vertical Controls Probe Attenuation Control Probe Attenuation Control The probe attenuation control changes the attenuation factor for the probe. The attenuation factor changes the vertical scaling of the oscilloscope so that the measurement results reflect the actual voltage levels at the probe tip. To change the probe attenuation factor for channel 1, press the 1 front panel key. Press the Probe menu key to change the attenuation factor to match the probe being used. Figure 2-7 shows an example for using a 1000:1 probe. Figure 2-7 Probe Attenuation Probe Attenuation Set to 1000:1 Table 2-1 Probe attenuation factors and corresponding settings 1:1 10:1 100:1 1000:1 1X 10X 100X 1000X 2-11 Vertical Controls Invert Control Invert Control The invert control inverts the displayed waveform with respect to the ground level. When the oscilloscope is triggered on the inverted waveform, the trigger is also inverted. To invert the waveform on channel 1, press the 1 front panel key. Press the Invert menu key until ON appears. Figure 2-8 and Figure 2-9 show the changes before and after inversion. Figure 2-8 The waveform before inversion. 2-12 Vertical Controls Invert Control Figure 2-9 The waveform after inversion. 2-13 Vertical Controls Digital Filter Controls Digital Filter Controls Pressing the Digital Filter menu key displays the Filter Controls. The filter controls set the digital filter used to filter the sampled waveform data. The types of filters that are available are shown in Table 2-2. Table 2-2 Filter Menu Menu Digital Filter Filter Type Setting Description Turns the filter for this channel on and off LPF (Low Pass Filter) HPF (High Pass Filter) BPF (Band Pass Filter) BRF(Band Reject Filter) Upper Limit Lower Limit The front panel entry knob sets the high limit The front panel entry knob sets the low limit ON OFF Pressing the Upper Limit or the Lower Limit menu keys turns the front panel entry knob into a control that can set the high and low frequency limits of the digital filter. The horizontal scale control determines the maximum value for the upper and lower limits. 2-14 Vertical Controls Math Functions Control Math Functions Control The math functions control allows the selection of the math functions add, subtract, multiply, and FFT (Fast Fourier Transform) for CH1 and CH2. The mathematical result can be measured visually and also using the cursor controls. To select a math function, press the Math button to display the Math menu. The settings of this menu are shown in the Table 2-3. The amplitude of the math waveform can be adjusted by pressing the 1/2 key, selecting the scaling control, and turning the entry knob. The adjustment range is in a 1-2-5 sequence from 1 mV/div to 10 kV/div. The scale setting is displayed above the status bar. The position of the math function can be similarly adjusted. Figure 2-10 Math Scale Math Function Definition 2-15 Vertical Controls Math Functions Control Figure 2-11 Math Scale Setting Table 2-3 Math Menu Menu Operation Settings Description Add source A to source B Subtract source B from source A Multiply source B by source A Fast Fourier Transform Set CH1 or CH2 as source A Set CH1 or CH2 as source B Inverted display of the Math waveform. Non-inverted display of the Math waveform. A+B A-B AxB FFT CH1 CH2 CH1 CH2 ON OFF Source A Source B Invert 2-16 Vertical Controls Math Functions Control Using the FFT The FFT math function mathematically converts a time-domain waveform into its frequency components. FFT waveforms are useful for finding the harmonic content and distortion in systems, for characterizing noise in DC power supplies, and for analyzing vibration. The FFT of a waveform that has a DC component or offset can cause incorrect FFT waveform magnitude values. To minimize the DC component, choose AC Coupling on the source waveform. To reduce random noise and aliasing components in repetitive or single-shot waveforms, set the oscilloscope acquisition mode to averaging. To display FFT waveforms with a large dynamic range, use the dBVrms scale. The dBVrms scale displays component magnitudes using a log scale. Selecting an FFT Window There are 4 FFT windows. Each window has trade-offs between frequency resolution and amplitude accuracy. Your source waveform characteristics along with your measurement priorities help determine which window to use. Use the following guidelines to select the best window. Table 2-4 FFT Windows Window Rectangle Characteristics Best frequency resolution, worst magnitude resolution. This is essentially the same as no window. Best for measuring Symmetric transients or bursts. Equal-amplitude sine waves with fixed frequencies. Broadband random noise with a relatively slowly varying spectrum. Hanning and Hamming Better frequency, poorer magnitude Sine, periodic, and narrow-band random accuracy than Rectangular. Hamming noise. Asymmetic transients or bursts. has slightly better frequency resolution than Hanning. Best magnitude, worst frequency resolution. Single frequency waveforms, to find higher order harmonics. Blackman 2-17 Vertical Controls Math Functions Control Key points The FFT resolution is the quotient of the sampling rate and the number of FFT points. With a fixed number of FFT points, the lower the sampling rate the better the resolution. The Nyquist frequency is the highest frequency that any real-time digitizing oscilloscope can acquire without aliasing. This frequency is half that of the sample rate, provided it is within the analog bandwidth of the oscilloscope. Frequencies above the Nyquist frequency will be under sampled, which causes aliasing. 2-18 Vertical Controls Reference Control Reference Control The reference control saves waveforms to a nonvolatile waveform memory. The reference function becomes available after a waveform has been saved. To display the reference waveform menu, press the Ref button. Table 2-5 Ref Menu Menu Source Save Invert Settings Comments Select channel for the reference memory. Save selected source waveform into nonvolatile waveform memory. CH1 CH2 ON OFF Inverted display of the reference waveform. Non-inverted display of the reference waveform. Figure 2-12 Ref Menu 2-19 Vertical Controls Reference Control Saving a Reference Waveform. 1 Push the Ref button to show the reference waveform menu. 2 Set the Source to CH1 or CH2 to select the channel you want. 3 Press Save to save the selected channel into the reference memory. The reference function is not available in X-Y mode. You cannot adjust the horizontal position and scale of the reference waveform. 2-20 Vertical Controls Removing Waveforms from the Display Removing Waveforms from the Display The channel 1 and channel 2 waveforms are turned on and off by pressing the 1 and 2 buttons on the front panel. The math functions and reference waveforms are similarly turned on and off by pressing the Math and Ref buttons on the front panel. 2-21 Horizontal Controls The oscilloscope shows the time per division in the status bar. Since all waveforms use the same time base, the oscilloscope only displays one value for all channels, except when you use Delayed Sweep. The horizontal controls can change the horizontal scale and position of waveforms. The horizontal center of the screen is the time reference for waveforms. Changing the horizontal scale causes the waveform to expand or contract around the screen center. The horizontal position knob changes the position of the trigger point relative to the center of the screen. 2-22 Horizontal Controls Horizontal System Setup Horizontal System Setup Figure 2-13 shows the front panel horizontal system controls. Figure 2-13 Scale knob Horizontal Controls Position knob The following exercise guides you through these buttons, knobs, and status bar. 1 Turn the scale knob and notice the change it makes to the status bar. The scale knob changes the sweep speed in a 1-2-5 step sequence and the value is displayed in the status bar. 2 Turn the position knob to move the trigger point with respect to the center of the screen. 3 Press the Main/Delayed key to display the associated menu. In this menu, you can enter or exit the Delayed Sweep mode, set the display to Y-T or X-Y format, and alter the Trig-Offset and Holdoff values. Pressing the horizontal scale knob is another way to enter or exit the delayed sweep mode. 2-23 Horizontal Controls Horizontal Knobs Horizontal Knobs The position knob adjusts the horizontal position of all channels and math functions. The resolution of this control varies with the time base. The oscilloscope digitizes waveforms by acquiring the value of an input waveform at discrete points. The time base allows you to control the sampling rate of this digitizing process. The horizontal scale control changes the horizontal time/div of the main time base. When delayed sweep is enabled, the horizontal scale control changes the width of the delayed sweep window. 2-24 Horizontal Controls Horizontal Menu Horizontal Menu Pressing the Main/Delayed button displays the associated menu. Figure 2-14 shows the screen icon descriptions and control indicators. Figure 2-14 Displayed waveform window ([ ]) position in memory. Trigger position in memory. Trigger position in waveform window. Sample Rate Horizontal scale setting. Status bar, trigger position, and horizontal scale controls indicators Delayed Sweep The Delayed Sweep is used to magnify a portion of the main waveform window. You can use Delayed Sweep to locate and horizontally expand part of the main waveform window for a more detailed (higher horizontal resolution) analysis of the waveform. The Delayed Sweep time base setting cannot be set slower than the Main time base setting. 2-25 Horizontal Controls Horizontal Menu Figure 2-15 Delayed Sweep window Delayed Sweep window view Delayed Sweep Window The screen is divided into two parts. The top half of the display shows the main waveform window. The bottom half of the displays shows an expanded view of the main waveform window. This expanded portion of the main window is called the Delayed Sweep window. Two blocks shadow the top half, the unshadowed portion is expanded in the lower half. In this mode, the horizontal position and scale knobs control the size and position of the Delayed Sweep window. To change the Main time base, you must turn off the Delayed Sweep mode. Since both the Main and Delayed Sweep windows are displayed, there are half as many vertical divisions so the vertical scaling is doubled. Notice the changes in the status bar. The Delayed Sweep function can also be activated by pressing the horizontal scale knob. 2-26 Horizontal Controls Horizontal Menu X-Y Format This format compares the voltage levels of two waveforms point by point. It is useful for studying phase relationships between two waveforms. This format only applies to channels 1 and 2. Choosing the X-Y display format displays channel 1 on the horizontal axis and channel 2 on the vertical axis. The oscilloscope uses the untriggered acquisition mode and waveform data is displayed as dots. The sampling rate can vary from 2 kSa/s to 100 MSa/s, and the default sampling rate is 1 MSa/s. Figure 2-16 X-Y display format The following modes or functions are not available in X-Y format. • Automatic Measurements • Cursor Measurements • Mask Test • Ref and Math Operations • Delayed Sweep • Vector Display Mode • Horizontal position knob • Trigger Controls Trig-Offset Reset This control resets the horizontal position to center screen or zero trigger offset. 2-27 Horizontal Controls Horizontal Menu Holdoff Holdoff can be used to stabilize a waveform. The holdoff time is the oscilloscope's waiting period before starting a new trigger. During the holdoff time oscilloscope will not trigger until the holdoff has expired. Figure 2-17 Holdoff The following exercise guides you through setting the holdoff time. 1 Press the Main/Delayed front panel button to display the associated menu. 2 Select the Holdoff menu button. 3 Adjust the entry knob to change the Holdoff time until the waveform is stable. 4 Press the Holdoff Reset menu button to change the Holdoff time to the 100 ns minimum value. 2-28 Horizontal Controls Roll Mode Roll Mode Roll mode continuously moves data across the display from left to right. It allows you to see dynamic changes (like adjusting a potentiometer) on low frequency waveforms. Two frequently used applications are transducer monitoring and power supply testing. When in the Roll Mode, the oscilloscope is untriggered and runs continuously. You can also make automatic measurements in the roll mode. The oscilloscope automatically enters the Roll Mode when the Horizontal Scale control is set to 50 ms/div or slower and the trigger sweep is set to Auto. 2-29 Trigger Controls The trigger determines when the oscilloscope starts to acquire data and display a waveform. When a trigger is set up properly, it can convert unstable displays or blank screens into meaningful waveforms. The oscilloscope acquires data while waiting for the trigger condition to occur. After it detects a trigger, the oscilloscope continues to acquire enough data so that it can draw the waveform on the display. 2-30 Trigger Controls Trigger System Setup Trigger System Setup Figure 2-18 shows the front panel trigger system controls. Figure 2-18 Trigger level knob Trigger Controls The following exercise guides you through these trigger buttons, knobs, and status bar. 1 Turn the trigger Level knob and notice the changes it makes to the display. As you turn the Level knob two things happen on the display. First, the trigger level value is displayed at the lower left-hand corner of the screen. Second, if the trigger coupling is DC or HF Reject, a line is displayed showing the location of the trigger level with respect to the waveform. 2 Change the trigger setup and notice how these changes affect the status bar. a Press the Mode/Coupling button in the trigger controls area. The Trigger menu appears. Figure 2-19 displays this trigger menu. 2-31 Trigger Controls Trigger System Setup Figure 2-19 Trigger Menu b Press the Mode menu button and notice the differences between Edge trigger, Pulse trigger, and Video trigger. Leave in the Edge mode. c Press the trigger Slope menu button to notice the differences between rising edge and falling edge. d Press the trigger Source menu button to select trigger source choices. e Press the Sweep button to select Auto or Normal. f Press the Coupling menu button and notice how AC, DC, LF Reject, and HF Reject affect the waveform display. 3 Press the 50% key and observe that the trigger level is set to the center of the waveform. 4 Press the Force button to start an acquisition even if a valid trigger has not been found. This button has no effect if the acquisition is already stopped. The Force button has another function called Local when the oscilloscope is being remotely controlled. When the oscilloscope is being remotely controlled, the front panel keys are disabled. By pressing the Force (Local) key, the oscilloscope front panel keys will be reenabled. 2-32 Trigger Controls Trigger Modes Trigger Modes The oscilloscope provides three trigger modes: edge, pulse, and video. Edge trigger can be used with analog and digital circuits. An edge trigger occurs when the trigger input passes through a specified voltage level with the specified slope. Pulse trigger is used to find pulses with certain pulse widths. Video is used to trigger on fields or lines for standard video waveforms. Edge Trigger The Slope and Level controls help to define the Edge trigger. The Slope control determines whether the oscilloscope finds the trigger point on the rising or the falling edge of a waveform. The Level control determines voltage point on the waveform where the trigger occurs.

Figure 2-20 Video Line Trigger 2-35 Trigger Controls Trigger Modes Figure 2-21 Video Field Trigger 2-36 Waveform Controls Figure 2-22 shows the location of the Acquire button in the Waveform section of the front panel. Figure 2-22 Waveform Controls Pressing the Acquire button displays the Acquire menu as follows: Table 2-9 Menu Mode Settings Normal Average Peak Detect Real Time Equ-Time 2 to 256 Comments Normal acquisition mode Average acquisition mode Peak Detect acquisition mode Real time sampling mode Equivalent time sampling mode Step by multiple of two. Set average counts from 2 to 256 Activate sequential capture, store, and playback Sampling Averages Sequence Select Real Time sampling to observe single-shot or pulse waveforms. Select Equ-Time sampling to observe high frequency repetitive waveforms. To reduce the displayed random noise, select the Average acquisition. This mode decreases screen refresh rate. To avoid waveform aliasing, select Peak Detect acquisition. 2-37 Waveform Controls Stop Acquisition Stop Acquisition When acquisition is stopped, the last acquired waveform is displayed. The waveform can be moved by using the vertical and horizontal controls. When the horizontal scale is set to 20 ns or faster, the oscilloscope uses sine(x)/x interpolation to expand the horizontal signal resolution. Equivalent Time Sampling The equivalent time sampling mode can achieve up to 20 ps of horizontal resolution (equivalent to 50 GSa/s). This mode is good for observing repetitive waveforms and should not be used for single-shot events or pulse waveforms. Average Acquisition The Average Acquisition mode should be used to remove random noise from the waveform and to improve measurement accuracy. See Figure 2-23 and Figure 2-24.

Performance verification for the products covered by this manual consists of three main steps: • Performing the internal product self-tests to ensure that the measurement system is functioning properly • Calibrating the product • Testing the product to ensure that it is performing to specification Performance Test Interval The procedures in this section may be performed for incoming inspection and should be performed periodically to verify that the oscilloscope is operating within specification. The recommended test interval is once per year or after 2000 hours of operation. Performance should also be tested after repairs or major upgrades. Performance Test Record A test record form is provided at the end of this section. This record lists performance tests, test limits and provides space to record test results. Test Order The tests in this section may be performed in any order desired. However, it is recommended to conduct the tests in the order presented in this manual as this represents an incremental approach to performance verification. This may be useful if you are attempting to troubleshoot a suspected problem. Test Equipment Lists of equipment needed to conduct each test are provided for each test procedure. The procedures are written to minimize the number and types of oscilloscopes and accessories required. The oscilloscopes in these lists are ones that are currently available for sale by Agilent at the time of writing this document. In some cases, the test procedures use features specific to the oscilloscopes in the recommended equipment 4-3 Service list. However, with some modification to the test procedures, oscilloscopes, cables and accessories that satisfy the critical specifications in these lists may be substituted for the recommended models with some modification to the test procedures. Contact Agilent Technologies for more information about the Agilent products in these lists. 4-4 Service Before Performing Performance Verification Testing Before Performing Performance Verification Testing Let the oscilloscope warm up before testing The oscilloscope under test must be warmed up (with the oscilloscope application running) for at least 30 minutes prior to the start of any performance test.

This is a Safety Class I instrument (provided with terminal for protective earthing). Before applying power, verify that the correct safety precautions are taken (see the following warnings). In addition, note the external markings on the instrument that are described under "Safety Symbols." Warnings • Before turning on the instrument, you must connect the protective earth terminal of the instrument to the protective conductor of the (mains) power cord. The mains plug shall only be inserted in a socket outlet provided with a protective earth contact. You must not negate the protective action by using an extension cord (power cable) without a protective conductor (grounding). Grounding one conductor of a two-conductor outlet is not sufficient protection. • Only fuses with the required rated current, voltage, and specified type (normal blow, time delay, etc.) should be used. Do not use repaired fuses or shortcircuited fuseholders. To do so could cause a shock or fire hazard. • If you energize this instrument by an auto transformer (for voltage reduction or mains isolation), the common terminal must be connected to the earth terminal of the power source. • Whenever it is likely that the ground protection is impaired, you must make the instrument inoperative and secure it against any unintended operation. • Service instructions are for trained service personnel. To avoid dangerous electric shock, do not perform any service unless qualified to do so. Do not attempt internal service or adjustment unless another person, capable of rendering first aid and resuscitation, is present. • Do not install substitute parts or perform any unauthorized modification to the instrument. • Capacitors inside the instrument may retain a charge even if the instrument is disconnected from its source of supply. • Do not operate the instrument in the presence of flammable gasses or fumes. Operation of any electrical instrument in such an environment constitutes a definite safety hazard. • Do not use the instrument in a manner not specified by the manufacturer. To clean the instrument If the instrument requires cleaning: (1) Remove power from the instrument. (2) Clean the external surfaces of the instrument with a soft cloth dampened with a mixture of mild detergent and water. (3) Make sure that the instrument is completely dry before reconnecting it to a power source. Safety Symbols !
