Wavelength Check Failed; Filter Check Failed - Agilent Technologies 1260 Infinity User Manual

Wavelength Check Failed

The automatic wavelength check after lamp ignition has failed. When the lamp
is switched on, the detector waits 1 minute to warm-up the lamp. Then a check
of the deuterium emission line (656 nm) via the reference diode is performed.
If the emission line is more than 3 nm away from 656 nm, the error message is
generated.
Probable cause
1 Calibration incorrect.

Filter Check Failed

The automatic filter check after lamp ignition has failed. When the lamp is
switched on, the detector moves the cutoff filter into the light path. If the filter
is functioning correctly, a decrease in lamp intensity is seen. If the expected
intensity decrease is not detected, the error message is generated.
Probable cause
1 Filter motor defective.
2 Defective or missing filter.
