imbalance rate of each phase will change gradually until they become stable.
You may also press “Re-test” button to quickly refresh the data. Repeat the
above-mentioned procedure until all the tapping tests are completed.

Upon the completion of the measurement, press the “Exit” key to

end the measurement. At this time, the DC resistance tester starts to
discharge and the display gives corresponding discharge indication and
the buzzer rings. After the discharge is completed and the tester returns
to the initial interface, the measurement wiring may be removed.

V. Precautions

1

When measuring the no-load voltage changing transformer, be sure to

exit from the discharge before switching the tapping switch. Do not switch the
tapping switch before the discharge is completed according to the discharge
indication.

2

Do not remove the wiring during the measurement.

3

If the charging progress strip and the current display value stand still

for a long time, it indicates that the value of the resistance value to be
measured is probably beyond the measuring scope of the current, so it is not
able to reach its set value. At this time, press the “Exit” button to return and
reselect the current to retry.

4

When replacing the fuse tube and the fittings, please use the same

model as this instrument.
