Figure 35: AC Input Voltage Calibration
2.
For each input phase use a voltmeter to measure between the phases (Line 1 = L1 to L2; Line2
= L2 to L3; Line 3 = L3 to L1).
3.
Enter the measured values into the screen and select Confirm.
This completes the ac input voltage calibration.

POWER MODULE AC OUTPUT VOLTAGE CALIBRATION
Use this function if it becomes necessary to recalibrate the voltage readings of any of the UPS's
output phases.
Note that this does not refer to the output reading of a particular module, but rather to the
output of all modules together.
Auto Correction is enabled by default. This is the recommended setting for most
situations.
After performing any calibrations or adjustments the Auto Correction feature
should be re-enabled, for optimal system performance.
To perform power module ac output voltage calibration:
