General Errors (Continued)
0601 Filter #1 Gain out of range
0602 Filter #2 Gain out of range
0603 Filter #3 Gain out of range
0604 Filter #4 Gain out of range
0605 Filter #5 Gain out of range
These errors indicate that the gain for the filter in question is out of the range
necessary to ensure performance to specifications.
Probable Causes:
• Defective interference filter.
• Defective lamp providing reduced signal, causing the error.
• Misaligned optics.
0700 Reader failed noise test
Significant variations in background electronic noise were detected when
blocking the light and increasing the gain to maximum.
Probable Causes:
•
External signals may be penetrating the measurement chamber. Ensure
that the bottom and top shrouds, as well as the filter wheel cover, are
correctly installed.
•
A faulty motherboard (PN 7330400, 7330410, or 7330415) or daughter
board (PN 7330404 or 7330414).
•
Photodiode or power supply may be too close to the instrument.
•
Failure indicates excessive variation in the dark current (background)
noise levels of the measurement circuit.
0800 Reader failed offset test
During self-test, the background electronic signal detected is outside of
acceptable limits at maximum gain when blocking the light.
Probable Causes:
•
If noise Max is > 20000.
There may be an ambient light leak. Ensure that the plate carrier
door is properly closed.
Faulty motherboard (PN 7330400, 7330410, or 7330415) or daughter
board (PN 7330404, or 7330414).
Photodiode or power supply may be too close to the instrument.
