HEALTH MONITOR Section of the Screen
The HEALTH MONITOR section of the status screen reports errors or
failures of the key hardware functions. The OK summary message at
the end of the HEALTH MONITOR line indicates that no errors or
failures were detected. Error indicates that one or more hardware tests
failed.
For each hardware function, OK is reported when it is operating
normally; Err is displayed when a failure or an error is detected.
Hardware functions are monitored periodically, with the exception of
Self Test, which is performed at powerup or when requested.
The health and status indicators in the HEALTH MONITOR section
are described as follows:
Self Test Last diagnostic check of the microprocessor system,
reference oscillator, satellite receiver, and power
supplies failed.
Int Pwr Internal power supply voltage(s) exceeds tolerance.
Oven Pwr Oscillator oven power supply voltage exceeds tolerance.
OCXO Oscillator output failed.
EFC Oscillator control voltage is at or near full-scale.
GPS Rcv Satellite receiver communication failed, or GPS 1PPS
reference is absent.
