Figure 37: Modules Input Current Calibration
2.
Measure the current on the input phase with an ammeter.
For your reference, the present UPS measured values are displayed on the right
side of the screen.

Type the measured value into this screen and select Confirm.
This completes module input current calibration.
8.2.2.4.
POWER MODULE OUTPUT CURRENT CALIBRATION
Use this function if it becomes necessary to recalibrate the current (ampere) readings of one of
the UPS's output phases.
The modules output current calibration can be performed on all modules simultaneously,
however it is recommended to perform modules output current one module at a time until all
modules have been calibrated.
An external load bank will be necessary in order to perform this calibration.
