Section 6: AccuLase-GPA™ Troubleshooting
6.1 Overview
This section provides information on troubleshooting and resolving some basic issues which may occur
during the operation of the AccuLase-GPA™
6.2 Diagnostic Alarms
The AccuLase-GPA™ is equipped with several self-diagnostic alarms which may be generated to indicate
a problem with the analyzer.
If an alarm is present there are two indications on the local display. The first is a flashing yellow caution
triangle in the upper right corner of the display. The second is a red LED located above the display that is
labelled “Alarm”. To determine what alarm is active use the “Panel Next” key on the keypad to navigate
to the “Alarms” page.
The presence of an alarm is also indicated in the browser based GUI by a red flashing bell icon at the top
right of the screen.
Table 19 below describes these alarms and how to resolve them:
