Problems such as low gas pressure, high backgrounds, and communication
failures within the instrument are described in this display. This should be the
first step in any attempt to troubleshoot the PCM-2.
The operator may press the F2 key while in this display to clear the transaction
buffer. When the STORE TRANSACTIONS variable in the instrument
configuration screen is set to "YES", all measurement results are saved in the
non-volatile memory of the unit's front panel board. If this data is not collected
by a host computer the buffer will eventually overflow and the PCM-2 will be
removed from service. This condition will be corrected if a host computer polls
out the accumulated transactions or if the buffer is forcibly cleared with the F2
key (all transaction data will be lost). The operator may also clear any
Contaminated Detector alarms which may exist by pressing the F3 key.
Contaminated detector conditions are self-clearing but may be cleared manually, if
desired.
This screen presents an overview of the PCM-2 in the form of a detector map.
Detectors which are operating normally are shown in green, while those which are
unusable due to high background or sensitivity problems are colored blue. If both
the alpha and beta channels of a detector have been deactivated (through the
detector parameter edit screen), that detector will be depicted in gray.
