Error Message
Description of error and action required
CONNECTIONS
REVERSED
H and X test lead connections are reversed.
Connect H and X test leads properly.
TURN RATIO >20,000
The tested turns ratio is higher than 20,000:1.
Causes test to stop. Check for bad or open test
lead connections.
Transformer winding(s) is open. Fix the problem
before continuing the test.
TURN RATIO < 0.8
The tested turns ratio is less than 0.8:1. Causes
test to stop. Check for bad or shorted test lead
connections.
Transformer has a winding turn(s) shorted. Fix
the problem before continuing the test.
UNIT NOT CALIBRATED
Tested turns ration is not calibrated. Contact
factory for possible problem(s).

PRINT
ERROR
There was an error during printing a report. Try again.
See
Table 5.1.
If failed, contact the factory for repair.
When an error message appears on a screen indicating an abnormal operating
condition, verify the condition by taking a repeat measurement before attempting
to take any corrective action. Also, refer to the Troubleshooting section for
malfunctions and possible causes.
Open connections, wrong connections, open windings, shorted windings, high
resistance windings, other abnormal transformer problems, or a combination of
these may cause a large deviation from nominal turn ratio or indicate an unusual
message. The unusual operating conditions may be caused by an abnormal
leakage reactance or capacitive coupling within the transformer windings.
