CALIBRATION ERROR CODES
If an error code is displayed during calibration it will be accompanied by a Clipboard icon and a
number to indicate the cause of the error. The first time that an error is displayed, it will be possible
to repeat the erroneous measurement. If the same error message is shown after the repeat
measurement, the complete calibration process will need to be repeated. The table below shows
the error codes:

Issue
Absorbance range of calibration blanking solution for calibration
steps is too large
Background absorbance (330nm) of calibration solution is too
large (first calibration solution)
Background absorbance (330nm) of calibration solution is too
large (second calibration solution)
Variance in pair of calibration solution results is too large
Calculated calibration pathlength factors are too large
Absorbance range of calibration blanking solution for verificati on
steps is too large
Calibrated verification absorbances are outside of acceptable
limits
Solution
Ensure that there is not a sample on the micro volume accessories read head.
Ensure the instrument lid is closed before and during the calibration.
Ensure the lamp is working – if the lamp has failed please request service
assistance.
Ensure the correct path length is being used.
Ensure the sample isn't so dense so that light is not transmitted through the
sample.
Ensure the lamp is working.
