5.4 Error messages
5.4.1 Type of error
Errors which occur during commissioning or measuring operation are displayed immediately. If two
or more system or process errors occur, the error with the highest priority is the one shown on the

The measuring system distinguishes between two types of error:
•
System errors: This group comprises all device errors, e.g. communication errors, hardware
errors, etc.
