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 (see
the Service Manual).
Test Functions
A series of test functions are available for troubleshooting and operational
verification after exchanging internal components (see
Service Manual).
Wavelength Verification / Recalibration
Wavelength recalibration is recommended after repair of internal components,
and on a regular basis to ensure correct operation of the
detector
calibration (see
Manual).
Diagnostic Signals
The detector has several signals (internal temperatures, voltages and currents
of lamps) that can be used for diagnosing baseline problems (see
