9160 EEPROM checksum mono correction
The monochromator wavelength may not be accurate. Because of this the
instrument may fail to find a particular Hollow Cathode lamp Resonance Line,
resulting in
No Peak Detected errors. If the error persists, a service call may be
required.
9307 RBC/Mains frequency below 48Hz.
The instrument detected a power mains supply fault: Low mains frequency.
Possible causes include:
 Power supply failure.
 Faulty RBC (Rotating Beam Combiner) on double beam instruments only.
 Faulty Mains Supply to the instrument.
If the error persists, a service call may be required.
9308 RBC/Mains frequency
The instrument detected a power mains supply fault: Mains frequency out of
range.
Possible causes include:
 Power supply failure.
 Faulty RBC (Rotating Beam Combiner) on double beam instruments only.
 Faulty Mains Supply to the instrument.
If the error persists, a service call may be required.
9309 RBC/Mains frequency above 62Hz
The instrument detected a power mains supply fault: High mains frequency.
Possible causes include:
 Power supply failure.
 Faulty RBC (Rotating Beam Combiner) on double beam instruments only.
 Faulty Mains Supply to the instrument.
If the error persists, a service call may be required.
