Now, the dc resistance tester starts to display the resistance value of each phase. With the
resistance value of each phase becoming stable, the imbalance rate will gradually decrease.
Under such state, the “Tap” button may be pressed to adjust and set the current tap value or
winding name so as to mark the measurement result. After the “Tap” button is pressed down, the
multi-functional key on the right becomes “▲”“▼”“
”“OK” and “Cancel”, and the tap
setting dialogue box is ejected. After setting, press the “OK” button to save it and press the
“Cancel” button to modify it. Then, press “Store” and “Print” button to save or print the
measurement results. In case of any doubt about the data, press “Retest” button to carry out the
measurement and calculation again. The maximum display scope of the imbalance rate is 50%. If
such scope is exceeded, only “50%” will be display.
When measuring the on-load voltage changing transformer, after the testing data of one tapping
position becomes stable, the on-load tapping switch may be switched to the next tapping position,
without discharging to conduct the measurement over again. At this time, the resistance value
and 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
