Overview of the Detector’s Indicators and Test Functions
Status Indicators
The detector is provided with two status indicators which indicate the
operational state (prerun, run, and error states) of the detector. The
status indicators provide a quick visual check of the operation of the
detector.
Error Messages
In the event of an electronic, mechanical or hydraulic failure, the detector
generates an error message in the user interface. For each message, a
short description of the failure, a list of probable causes of the problem,
and a list of suggested actions to fix the problem are provided.
Test Functions
A series of test functions are available for troubleshooting and operational
verification after exchanging internal components.
Wavelength Verification / Recalibration
Wavelength recalibration is recommended after repair of internal
components, and on a regular basis to ensure correct operation of the
detector. The detector uses the deuterium alpha and beta emission lines
for wavelength calibration.
Diagnostic Signals
The detector has several signals (internal temperatures, voltages and
currents of lamps) that can be used for diagnosing baseline problems.
