5.3 Error message display
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 always the one shown
on the display. The measuring system distinguishes between two types of error:
• System error: this group includes all device errors, for example communication errors, hardware
errors, etc.

Page 48
• Process error: this group includes all application errors, for example “DSC SENSOR LIMIT”, etc.
