9.1 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.
9.2 System error messages
You can display and select the error messages with the MINUS key.
