Agilent 55B AA Spectrometer User’s Guide 143
9310 Optical RBC frequency
Instrument fault. The instrument detected a problem with the RBC. A service call
may be required.
Optical sensor or associated circuitry may be faulty.
9311 Instrument fault +12V PSU
Instrument Fault. The instrument detected a problem with the +12 volt supply. A
service call may be required.
9312 Instrument fault -12V PSU
Instrument Fault. The instrument detected a problem with the -12 volt supply. A
service call may be required.
9313 Instrument fault 5V PSU
Instrument Fault. The instrument detected a problem with the 5 volt supply. A
service call may be required.
9316 Wavelength out of range
The Instrument is reporting that the current method has specified a wavelength
that is out of range for the Photomultiplier Tube (PMT).
Possible causes include:
A method wavelength suitable for a Wide Range PMT was specified but the
instrument is currently fitted with a Short Range PMT. Use a valid wavelength.
Currently available PMTs:
Wide range: up to 900 nm.
9317 No peak: low HC lamp energy
Low hollow cathode lamp energy.
The instrument Gain had been raised to its highest value but the hollow cathode
lamp signal was too low.
