is only necessary to check Watthour calibration to ensure that all revenue quantities are accurate. However, some utilities are required by their Public Utilities Commissions to verify the accuracy of VArhour data as well as Watthour data. 1. Use MeterMate software to put the meter calibration LED into VArhour pulse output mode. 2. Set up the meter for testing as described above in Watthour Test Procedure. The test pulse value is now Kt VArhours per pulse. 3. Begin testing according to your standard VArhour test procedures. Allow 15 seconds of settling time after applying voltage before making accuracy measurements (20 seconds if modem installed). NOTE: Test conditions with high power factors require very long VArh test times. Typically VArh testing is done at 120V and 0.5 PF. 3.6 Battery Replacement Lithium Inorganic 3.6 Volt Battery (Safety Precautions) Do not expose battery to temperatures above 100 degrees C. Do not incinerate, puncture, crush, recharge, short circuit and over-discharge battery. The contents are water reactive and the battery contents can form HCL (hydrochloric acid), SO 2 (sulfur dioxide) and H 2 (hydrogen), upon contact with water (only when forced open). Do not expose contents of battery to water. Do not expose contents to high humidity for extended periods of time. Dispose of batteries in accordance with local, state and federal hazardous waste regulations. To obtain an MSDS ( Material Safety Data Sheet) , contact your local GE supplier. 3.6.1 Replacing the Battery Note: The battery should be replaced within 30 seconds of de-energizing the meter to avoid losing date/time information and forcing the meter into an Er 000002 state. 3.6.1.1 Replacing the Battery when a Battery Port is not Present on Meter Cover CAUTION - Battery installation must be done with NO power applied to the meter.

    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.

    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.
