Error Information

Holmium Oxide Test Failed

The holmium oxide test in the detector has failed. During the holmium test,
the detector moves the holmium filter into the light path, and compares the
measured absorbance maxima of the holmium oxide filter with expected
maxima. If the measured maxima are outside the limits, the error message is
generated.
Probable cause
1 Misaligned/defective grating assembly.

Grating/Filter Motor Test Failed

The motor test has failed.
Test 0 Failed: Filter motor.
Test 1 Failed: Grating motor
During the motor tests, the detector moves the motor to the end position while
monitoring the end-position sensor. If the end position is not found, the error
message is generated.
Probable cause
1 Defective motor assembly.
