UPS for 480 Vac Grid, User Guide, doc. rel.4.0
Calibration should be performed only under conditions where the input
voltages are stable and not subject to fluctuation.
The system must be in normal mode to perform this calibration.
1.
From the System Menu go to Modules > AC Output voltage calibration.
The AC output voltage calibration screen appears:
Figure 36: AC Output Voltage Calibration
2.
For each output phase use a voltmeter to measure between the phase to midpoint.
3.
Type the measured amount into this screen and select Confirm.
This completes ac output voltage calibration.

POWER MODULE INPUT CURRENT CALIBRATION
Use this function if it necessary to recalibrate the current (ampere) readings of any of the UPS's
input phases.
The modules input current calibration can be performed on all modules simultaneously, however
it is recommended to perform modules input current one module at a time until all modules have
been calibrated.
