When detecting an operating state which is not permissible, the device will display an error code

The following error codes are defined:

Indicates that the valid measuring range of the device has been exceeded.

Possible causes:

- Temperature too high.
- sensor broken.
- sensor is wrong connected

Remedies:

- The error-message will be reset if the input signal is within the limits.
- check probe and device configuration.

Indicates that the value is below the valid measuring range of the device.

Possible causes:

- Temperature is too low
- sensor shorted
- sensor is wrong connected

Remedies:

- The error-message will be reset if the input signal is within the limits.
- check probe and device configuration.

The device features an integrated self-diagnostic-function which checks essential parts of the de-
vice permanently. When detecting a failure, error-message Err.7 will be displayed.

Possible causes:

- Valid operating temperature range has been exceeded or is below the

 valid temperature range.

- Device defective.

Remedies:

- Stay within valid temperature range.
- Exchange the defective device.

The device features a built in diagnose function for the connected probe or transducer.
When this function is detecting an error the message Err.9 will be displayed.

Possible causes:

- probe broken or shorted
- sensor is wrong connected

Remedies:

- check probe and exchange defective probe, if necessary.

Indicates a measuring value, needed for calculation of the display value, is faulty or out of range.

Possible causes:

- one input signal has transgressed the measuring range or is not
   connected

Remedies:

- check probe and exchange defective probe, if necessary.
