Disabled for Form 45 and 56 meters used in a 4-wire wye or 4-wire delta service. TIP Triplen currents add in the neutral. The triplens are the harmonics that are simply multiples of three times the fundamental. The third, sixth, and ninth harmonics are examples of triplens. For example, if there are large third harmonic currents in the phases, the neutral current can be higher than the individual phase currents. 2.3.3.5 Diagnostic Output The Site Genie diagnostics can also be used to control switches on a meter’s I/O board. All diagnostics are supported and can drive several (any or all) solid- state relay (SSR) outputs on the I/O board. The outputs may be a Form A or Form C outputs. (See the I/O board specifications for ratings.) MeterMate programming software allows the user to select which diagnostics will control which outputs. Any or all of the diagnostics can be selected to activate any or several outputs. If any of the selected diagnostic conditions which are mapped to a specific output occur, then that output is activated. TIP Diagnostic events can also be recorded using the optional Event Recorder, enabled with the E soft switch, to determine the date/time when diagnostics occur. The meter must be operating in a Demand/LP or TOU mode for date/time information to be captured.

GEH-7285, kV2c Encompass Electronic Meter 3-2 Maintenance Instructions 3.1 Recommended Procedures The procedures described on the following pages are those recommended by the General Electric Company. Any procedures not described herein or referenced herein are not recommended. 3.1.1 Meter Testing Tools The meter is equipped with a light-emitting diode (LED) for calibration and a liquid crystal display with disk analog and test displays. The calibration LED is part of the OPTOCOM port as shown in Figure 3-1. 3.1.1.1 Calibration LED The OPTOCOM LED emits calibration pulses (infrared light) until the meter detects the presence of OPTOCOM communications. This LED is the source of Watthour and VArhour calibration pulses. Each calibration pulse is equal to the value assigned to Kt (Watthours or VArhours). The duration of each output pulse is approximately 25 milliseconds.

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
