13.2 TROUBLESHOOTING GUIDE
Issue Solution
Unable to achieve zero Ensure that there is not a sample in the sample chamber.
absorbance or 100% Ensure the instrument lid is closed before and during the calibration.
transmittance when Ensure the lamp is working – if the lamp has failed replace the lamp
calibrating (7310) or lamp module (7315).
Unable to achieve a reading Ensure the correct cuvette is being used so that light isn’t being
when measuring a sample absorbed by the cuvette.
Ensure the sample isn’t too dense that light is not transmitted through
the sample.
Ensure the lamp is working.

Unable to print results using Ensure internal printer selected in autolog menu.
the internal printer Ensure there is paper in the unit.
Ensure there is a result displayed on screen.
Unable to save results to Ensure the USB stick is inserted into the front of the unit
the USB memory stick Ensure the USB memory stick has free capacity
Ensure there is a result displayed on the screen.
Unable to continue kinetics Due to the nature of the kinetics measurements stopping the
measurement after measurement before completion will result in some measurement
cancelling abort action time being lost. Therefore the experiment cannot be continued. It must
be restarted.
