9.1 Instrument diagnostics and troubleshooting
The Diagnostics menu is used to analyze the device functions and offers comprehensive help for
troubleshooting. To find the causes for device errors or alarm messages, follow these basic proce-
dures.
General procedure for troubleshooting
1. Open diagnosis list: Lists the 10 most recent diagnostic messages. From this, you can tell which
errors/faults are currently pending or if one of them has occurred multiple times.
2. Open measured value display diagnostics: Verify the input signals by displaying the raw values
(mA, Hz, Ohm) or the scaled measuring ranges. To verify calculations, call up calculated aux-
iliary variables if necessary. Snapshot of raw value display.
3. Steps 1 and 2 remedy most causes of errors. If the error persists, observe the troubleshooting
instructions for the error types from Chapter 9.2 of the Operating Instructions.
4. If this is not successful, contact service. For service inquiries, please always have the error
number and the information from the Device information/ENP (program name, Serial Number
etc.) available.
