4 Troubleshooting and Test Functions
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 (see
page 75).
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 “Error Messages" on
page 77).
Wavelength Recalibration
Wavelength recalibration is recommended after repair of internal components
to ensure correct operation of the
detector. The detector uses specific
properties of the excitation and emission light characteristics, see
“Wavelength Verification and Calibration" on page 101).
Test Functi o ns
A series of test functions are available for troubleshooting and operational
verification after exchanging internal components (see “Test Functions" on
page 114).
