2.7.4

Generator Metering (and Calibration)

Displays generator output data including line-to-line and line-to-neutral voltages, current, frequency, total kilowatts, and total
kVA. The menu displays three-phase voltage and current readings when applicable.
All menu displays apply to both single-phase or three- phase voltages on the menu overview. The phase designation does not
appear in the controller menu displays. Some displays will show 0 values when single-phase connections are shown.
Note:
®
For Decision-Maker 3000 controllers with firmware versions before 3.0.25, see the section titled: GenSet Calibration, for
generator calibration.
Display also provides access to the calibration factors for metering (volts and amps). Changing the system voltage or replacing
the main logic control circuit board requires calibration adjustment. Connect a meter with a minimum accuracy of 1% to the
generator set output leads to calibrate the voltage-sensing logic.
