Diagnostics and repair
Acknowledging diagnostic alarms
Diagnostic alarms turn off when the problem is solved, except these alarms:
• Source wipe due
• Shutter check due
• Standardize due
Perform the procedure to acknowledge them.
Diagnostic alarm messages
Active alarm messages may appear on the Ohmview 2000 menu if the
alarm condition is selected. You can select individual alarm conditions in the
Alarms | Diagnostic Alarm Enable tab.
When a HART device initially connects to the gauge, any conditions in
alarm appear on the screen.
Note: If the relay is set as a diagnostic alarm, you must acknowledge
all diagnostic alarms to reset the relay.
