7 Diagnostics and troubleshooting
7.1 Troubleshooting instructions
The transmitter constantly monitors its functions itself. If an error occurs which the device
recognizes, this is indicated on the display. The error number is shown below the 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 localize and rectify the error.
These tables provide you with additional information on any spare parts required.
7.2 System error messages
The system error messages can be called up and selected with the MINUS key.
