9321 No peak: low HC lamp energy
Low hollow cathode lamp energy. Monochromator reference wavelength not
found.
The instrument Gain had been raised to its highest value but the hollow cathode
lamp signal was too low.
Possible causes include:
 Hollow cathode lamp misaligned.
 The light path is obstructed.
 Faulty hollow cathode lamp.
Suggested action:
Check that the optical light path is not obstructed in the sample compartment. Exit
then re-enter the Optimize page/window. This will cause the instrument to retry
the peaking.
9322 No peak: high HC lamp energy
High hollow cathode lamp energy. Monochromator reference wavelength not
found. The instrument Gain had been set to its lowest value but the hollow
cathode lamp signal was too high.
Possible causes include:
 Hollow cathode lamp misaligned.
 Faulty hollow cathode lamp.
 Faulty EHT circuit.
9323 Low emission: no peak
The instrument failed to peak at the selected wavelength. Low Emission energy at
the selected wavelength. The instrument Gain had been raised to its highest value
but the signal was too low.
Possible causes include:
 Flame not lit, or correctly aligned.
 Wrong wavelength selected.
 The standard solution currently being aspirated has low concentration.
 Emission Setup has not been performed.
 Faulty PMT or related circuits.
