Trouble-shooting instructions
The transmitter constantly monitors its functions itself. If an error occurs which the device
recognises, this is indicated on the display. The error number is under the unit display of the main
measured value. If more than one error occurs, you can call these up with the MINUS key.
Refer to the "System error messages" table for the possible error numbers and remedial measures.
Should a malfunction occur without any transmitter error message, please refer to the
"Process-specific errors" or the "Device-specific errors" tables to localise and rectify the error. These
tables provide you with additional information on any spare parts required.
