WARNING ASSOCIATED MEANING TYPICAL CAUSE
W-01 Lamp Failure The lamp is no longer working, or the light output
of the lamp is too low for normal operation.
W-02 Transmission detector #1 error Transmission detector #1 failed to report the
proper signal levels during calibration (the
detector circuitry has failed or calibration was
performed with the wrong standards).
W-03 Transmission detector #2 error Transmission detector #2 failed to report the
proper signal levels during calibration (the
detector circuitry has failed or calibration was
performed with the wrong standards).
W-04 Nephelometric detector (90°) error The nephelometric detector failed to report the
proper signal levels during calibration (the
detector circuitry has failed or calibration was
performed with the wrong standards).
W-05 Reference detector The reference detector failed to report the proper
signal levels during calibration (the detector
circuitry has failed or calibration was performed
with the wrong standards).
W-06 Calibration failure on range 0-10
NTU.
The signal difference obtained between the 0.02
NTU and 10.0 NTU calibration standards was too
small to ensure the resolution in the specifications.
Verify that you used the correct standards during
calibration.
W-07 Calibration failure on range 10-100
NTU.
The signal difference obtained between the 10.0
NTU and 100.0 NTU calibration standards was
too small to ensure the resolution in the
specifications. Verify that you used the correct
standards during calibration.
W-08 Calibration failure on range 100-1750
NTU.
The signal difference obtained between the 100.0
NTU and 1750.0 NTU calibration standards was
too small to ensure the resolution in the
specifications. Verify that you used the correct
standards during calibration.
WNG Multiple warnings have occurred Calibration was performed with the wrong
standards or the lamp failed during calibration.
