3.2.12 Meter Calibration Screen
Go to the Master Menu and move the highlighted cursor to METER CALIBRATION. Press the
Select pad and the Meter Calibration screen is displayed.
The Meter Calibration screen enables a Liebert field-service engineer to adjust the calibration of the
UPS metered functions at each cabinet. Access to these settings is limited by the Security Access con-
trol.
NOTE
Bypass volts are calibrated only at the System Control Cabinet (SCC). Input amps, DC volts,
DC amps and temperature are calibrated only at the UPS modules.
CAUTION
!
Meter calibrations are factory-set and should not require adjustment. Contact Liebert Global
Services for meter calibration.
WARNING
!
Do not attempt to calibrate meters without adequate training. Meter calibration requires
special test equipment, access to test points in sensitive circuitry and exposure to hazardous
voltage.
