Code
Description and Probable Causes:
0800
PMT failed Noise Offset where the initial offset value was not between 700 and 2450
(see the “offset voltage” on the system test)
This error indicates that during the system test, the background electronic signal that was
detected is outside of acceptable limits at 0 gain when blocking the light.
Probable Causes:
If the value is larger than 2450:
•
Too much light has saturated the PMT. Turn the unit off and wait 24 hours.
•
A faulty PMT analog PCB or faulty internal grounding may cause internal electronic noise,
or the motor power supply PCB is defective, or both.
•
PMT or PMT base is defective.
•
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.
If the value is less than 700:
•
PMT base cable lost ground connection. Rebuild connector.
•
PMT or PMT base defective or too quiet.
•
PMT analog PCB and/or Motor power supply PCB are defective.
Absorbance reference channel failed offset range
See “noise Max” < 20000 and “noise Min” > 10 on the system test.
This error indicates that during the system test, the background electronic signal that was
detected is outside of acceptable limits at maximum gain when blocking the light.
Probable Causes:
If noise Max is > 20000:
•
The photodetector is too noisy and is defective.
•
Absorbance channel analog PCB 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.
If noise Min is < 10:
•
The photodetector is not connected or is defective, giving a noise reading of zero.
•
Absorbance channel analog PCB is defective.
0810
Absorbance measurement channel failed offset range
See “noise Max” < 20000 and “noise Min” > 10 on the system test.
This error indicates that during the system test, the background electronic signal that was
detected is outside of acceptable limits at maximum gain when blocking the light.
Probable Causes:
If noise Max is > 20000:
•
The photodetector is too noisy and is defective.
•
Absorbance channel analog PCB is defective.
•
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
door are properly closed.
•
Electrical noise may be penetrating the measurement chamber. The bottom and top
