Cerabar PMP71B HART Diagnostic and troubleshooting
Hauser 53
11.1.3 Additional tests
If no clear cause of the error can be identified or the source of the problem can be both the
device and the application, the following additional tests can be performed:
1. Check the digital pressure value (display, HART, etc.).
2. Check that the device concerned is functioning correctly. Replace the device if the
digital value does not correspond to the expected pressure value.
3. Switch on simulation and check the current output. Replace the main electronics if
the current output does not correspond to the simulated value.
