‘LO xx’

Low. Measurement under range.

‘HI xx’

High. Measurement over range.

‘— H.M’

Dashes indicate no FF transducer signals.

‘OPEN PRB’

Open probe. Wiring to probe is open circuit. Check wiring and crimps. Swap probes to troubleshoot.

‘BAD-PRB’

Bad probe. Erratic reading. May be poor electrical connection. Swap probes to troubleshoot.

‘— GPH’

Dashes indicate no FF transducer signals.

‘0.0 GPH’

Zero’s indicate FF is too low to register.

‘TEST I NG’

‘Change’ tapped during self test. Tap ‘Change’ again later.

‘HOBS ON’

Not an error. Hobbs on. RPM exceeds the Hobbs RPM enable value.

‘MEM ON’

Not and error. Memory on. Recording is enabled when EGT exceeds 500 F or the RPM exceeds the Hobbs RPM value.

‘CONFIG ERR’

“Configuration Error” on the 930. “Config Err” on the 900.

If the 900/930 is an ‘experimental’ model then reload the configuration in the EDM. Then power up the 900/930 when done. If the ‘Config Err’ message still comes up then the CPU board has an issue and the EDM will need to come in for repair.

If the 900/930 is a ‘primary’ unit, then follow the ‘key’ change procedure and remove the ‘key’ in the unit. This key is located under the EDM’s label. After following the steps in the Key procedure, and it still comes up with the error, then it will need to come in for repair – a CPU board issue.

‘WARNCFG’
