Unformatted text preview: step 6 under “To create an EA-100 setup using Advanced Setup” on page 4-2-4. • While the E-CON main menu is on the display Starting a sampling operation while the E-CON main menu is on the display performs sampling using the contents of the current setup memory area (which were created using Setup Wizard or Advanced Setup). • While the setup memory list is on the display You can select the setup you want on the setup memory list and then start sampling. The following procedures explain the first three conditions described above. See “To recall a setup and use it for sampling” on page 4-3-3 for information about starting sampling from the setup memory list. 20011101 20010101 4-5-2 Starting a Sampling Operation u To start sampling 1. Start the sampling operation by performing one of the function key operations described below. • If the final Setup Wizard screen is on the display, press 1(YES). • If the Advanced Setup menu screen is on the display, press 1(START). • If the E-CON main menu screen is on the display, press 4(START). • This sets up the EA-100 using the setup data in the current setup memory area. • To interrupt a setup while the above screen is on the display, press A. 2. The sampling start dialog box appears after setup of the EA-100 is complete. • The content of the sampling start dialog box depends on the settings contained in the setup. See “Operations during a sampling operation” below for information about this dialog box and other display screens. u Operations during a sampling operation Sending a sample start command from the calculator to the EA-100 causes the following sequence to be performed. Setup Data Transfer → Sampling Start → Sampling End → Transfer of Sample Data from the EA-100 to the Calculator The table on the next page shows how the trigger conditions and sensor type specified in the setup data affects the above sequence. 20010101 20010101 6.

Perform the following procedure to ensure better sampling accuracy. Using a Heart Rate Sensor 1. Select [TRIGGER] as the Trigger Source item of Advanced Setup’s Trigger parameter. 2. When the EA-100 is in the Ready state prior to sampling, hold down the EA-100’s [TRIGGER] key for about 20 to 30 seconds, and then release it. 3. Press the EA-100’s [TRIGGER] key when you want to start sampling. Using a Conductivity or pH Sensor 1. Select [Yes] for the [Real-Time] setting on the Sample Setup screen of the Advanced Setup menu. # Initial samples using conductivity, heart rate, and pH sensors are always inaccurate when starting from Setup Wizard. # For detailed information about a sensor, see the documentation that comes with it. 20011101 20010101...
