10.1 eRRoR CoDeS
If an error code is displayed it will be accompanied by a spanner icon and a symbol to indicate if the
error is a warning ( caution icon) or fatal (stop icon). If the error is fatal contact your local distributor
or Jenway service department (refer to section 9.3). If the error is a warning it may be possible to retry
the test. In this case a
back icon will also be displayed. The table below shows the error codes:
error Code Symbol issue

The most likely causes of this error are:
Warning 1. The methods were reset by pressing the top left button during the
power on tests performed when the instrument is turned on.

itself.
Solution: Press the key adjacent to the tick icon to action.
err 3 Dark Calibration error
This error indicates that the dark level is too high during calibration. In
normal operation the lamp is switched off during an operator initiated
Warning calibration sequence to ensure that the detector output is below a
threshold level. The calibration is aborted and Err 3 is displayed if the
detector output is above the threshold level.
The most likely causes of this error are:
1. The sample chamber lid has been left open during the calibration
sequence.
Redo 2. The sample chamber lid was opened during the calibration sequence.
3. There is a fault on the detector PCB.
Solution: Ensure the sample chamber is closed completely. Press the key
adjacent to the back icon to retry the dark calibration.
