9. Start a recording
a. Change the Phase A Current phase angle on the PQ Simulator to -30°.
b. Change the Phase B Current phase angle on the PQ Simulator to -30°.
c. Change the Phase C Current phase angle on the PQ Simulator to -30°.
NOTE: The KW, KVA and KVA values on the DVM Demand screen.
d. Start the MPQ Recording.
Allow the unit to record for 20 minutes.
10. Energy
a. Stop the recording.
b. View the recorded energy graph on the unit.
Confirm the following:

Each KWH 5 minute interval = KW/12

Each KVAR 5 minute interval = KVAR/12

Each KVA 5 minute interval = KVA/12
This is because the demand interval was set to 5 minutes. There are 12 (5 minute)
intervals in an hour. So the power is aggregated over a 5 minute interval to calculate
energy. If the demand interval was set to 15 minutes then the energy would be
aggregated 4 times every hour. So if the active power draw was constant the over the
15 minute demand interval then the KWH = KW/4.
When verifying revenue meters the demand aggregation should be set to the same
value as the revenue meter.
NOTE: This data can also be transferred and viewed in the Megger PQ software.
