Appendix C: Error Codes
BioTek Instruments, Inc.
Code Description and Probable Causes:
shrouds are part of the electrical shielding. Check to see if the shrouds are installed and are
properly fastened.
If noise Min is < 10:
•
The photodetector is not connected, or the optic spray is damaged or defective, giving a
noise reading of zero.
•
Absorbance channel analog PCB is defective.
0900 The absorbance reference channel Dark current value failed
See “Dark” on the system test. See criteria in text below.
This error can indicate one of the following scenarios:
•
The reference channel failed during a read or spectral scan for one of the following reasons:
- Dark value was < 100 during a spectral scan using 8 flashes and 8 resets during
sweep mode.
-
Dark value was < 100 during a spectral scan using 8 flashes and the number of
resets saved for that wavelength during normal or rapid mode.
•
The reference channel failed < 100 or > 20000 during filter calibration or spectral scan with
the flash on.
•
The reference channel failed < 100 during filter calibration or spectral scan with the flash
off.
Probable Causes:
If failed < 100:
•
Absorbance analog PCB or reference channel analog PCB is defective.
•
Shielding of the cable between reference channel and analog PCB is defective or
disconnected.
•
Reference channel photodetector is defective.
If failed > 20000:
•
Reference channel photodetector is defective.
•
A faulty analog PCB or faulty internal grounding may cause internal electronic noise.
•
There may be an ambient light leak. Ensure the plate carrier door and the front hinged
door are properly closed.
•
Electrical noise may be penetrating the measurement chamber. The bottom and top
shrouds are part of the electrical shielding. Verify that the shrouds are installed and
properly fastened.
•
Order-sorting filter wheel is jammed, not aligning the filter wheel to block the light path, or
the filter is degraded and is not passing enough light energy.
0901 – 0906 The absorbance reference channel Dark current value failed
See “Dark” on the system test. See criteria in text below.
The last number is the lambda table position number. This error can indicate one of the
following scenarios:
•
The reference channel failed < 100 during the optic test with the flash on.
•
The reference channel failed < 100 during a read or blank read not in sweep mode with the
flash off.
•
The reference channel failed < 100 or the Dark value has changed more than 10% from the
last self-test data during a read or blank read with the flash on.
Probable Causes:
•
Absorbance analog PCB or reference channel analog PCB is defective.
•
Cable between reference channel and analog PCB is defective or disconnected.
•
Reference channel photodetector is defective or the optic spray is damaged.
•
A faulty analog PCB or faulty internal grounding may cause internal electronic noise.
•
There may be an ambient light leak. Make sure the plate carrier door and the front hinged
