Err 1
Fatal
System Parameters Failure
This error indicates that the essential system parameters are
corrupt.
The most likely causes of this error are:
1. Fram chip failure.
Solution:

Operating Parameters Failure
This error is a warning that the method and other user
parameters have been reset.
The most likely causes of this error are:
1. The methods were reset by pressing the top left button
during the power on tests performed when the instrument is
turned on.

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 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.
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.
Err 4
Fatal
Microswitch Failure (service only)
This error indicates that the microswitch was not found.
The most likely causes of this error are:
1. The microswitch is broken.
Solution:
