Displaying, Printing, and Clearing the Error Log
Detector errors and major detector events, such as power-on self-tests (POSTs), are logged to
a dedicated area in the memory of the detector. The log can hold 100 errors/events. When the
log is full, the next entry replaces the first entry. Therefore, Thermo Fisher Scientific
recommends that you print out the log and clear it periodically to keep a continuous record
for your maintenance files. The memory is protected by battery backup when the detector is
turned Off. View, print and clear the log weekly as part of your regular maintenance routine.
A list of error messages that can be displayed in the event log along with suggested solutions is
compiled in
Use the Error Log page in ChromQuest, shown in
, to retrieve, view, print, and clear
the event log for the detector. The event log collects messages regarding major events and
errors occurring in the detector. These messages are created as part of the normal operation of
the detector and can be helpful when attempting to troubleshoot communications problems.
