8 Diagnostics and troubleshooting
8.1 Trouble shooting instructions
The transmitter continuously 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.
