NOTE: Usually review two consecutive audit reports
before sending service personnel to investigate.
Remember, the audit system may be detecting
tampering of the EC unit.
In audit report analysis, the EC computer operator
will have to determine, from the audit reports, what
the servicer should examine on the EC units.
If the servicer cannot find a particular problem,
consult the appropriate audit reports for further analysis.
Cycle
test
Exit diagnostic test
NOTE: In the cycle audit test, the cycle count will not
advance on a "rapid advance" cycle. The manual
control audit or Micro-wand "show counts" will
have to be accessed to determine whether audit
counters are advancing. Also, the cycle count
does not activate until the end of the cycle.
