Failure message

Resistance test result: Fail – DELTA R. Delta R percent is out of tolerance.

Test results: Fail-OPEN LEADS. Open Leads

Detected.

Test Results: Fail-TOLERANCE Resistance(s) outside of user defined targeted range.

Resistance values must be greater than 0.500 ohms for HIGH VOLTAGE LEADS and greater than 0.001 for the RES LEADS. You may stop

Testing, reconfigure Test ID with the appropriate leads, and repeat the test OR continue with the remaining tests.

Test Results: Caution – MAX Resistance Range

Exceeded.

Possible Open lead(s).

Resistance values do not have a solvable solution.

Instrument detecting excessive electrical noise.

Resistance measurements are unstable. Check for noise sources nearby (welders, VFDs, etc.) or a free wheeling rotor.
