Ps Service; Ac Mains Meter Calibration - Harris Ranger Series Commissioning Manual

Section 3 Operation and Adjustments
3.8.1
This is an on-line help screen telling how to remove a power supply, but also allows for
calibration of the AC Mains reading on the Power supply screen in Figure 3-16.
!
CAUTION:
ALWAYS SHUT THE BREAKER OFF ON THE FRONT OF THE PA POWER
SUPPLY BEFORE REMOVING TO PREVENT DAMAGE TO CONTACTS AND/
OR THE POWER SUPPLY.
3.8.1.1
The AC Mains calibration must be done during transmitter installation, but will most
likely not require adjustment again unless the MOV or PS Monitor board is changed.
This is a critical transmitter adjustment as this reading is used for the AC high and AC
low faults.
NOTE:
This calibration should always be done with the transmitter shut off. This adjust-
ment can cause various power supply faults to appear momentarily, but can be
safely ignored. If the transmitter is turned ON, these faults can cause the transmit-
ter to mute momentarily.

WARNING: Disconnect primary power prior to servicing.
