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

Err 1 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: Restart the unit, if the problem persist, contact a service

technician.

Err 2 Operating Parameters Failure

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.

2. the parameters have been corrupted, so the instrument has reset

itself.

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.

Err 4 Microswitch Failure

This error indicates that the microswitch was not found.

The most likely causes of this error are:

Fatal 1. The microswitch is broken.
