after selecting the current, press START UP to start the test; meanwhile, the gauge will indicate all

the selected current values. When press START UP, few seconds later, it will display

"CHARGING", when it displays "TESTING" that means the “CHARGING” has been completed.

Few seconds after accessing the TEST STATUS it will show the measured resistance values.

(On-screen it will display the selected current value with all the measured resistance values, I = "

" A; R = " " m Ω / Ω).

4.

After the test

: press "RESET", and winding device will disconnect the power supply, discharge,

alarm, Ammeters back to zero, then restore status, and after the discharge alarm, re-connection,

proceed the next test or unplug the test cable and end the measurement.

VII. Caution

1. During the no-load measurement, before resetting the transformer invert load, wait the

discharge alarm stops, before switching the tap.

2. Wait till the discharge alarm stops before reconnecting wires

3. Before selecting the current, refer to the technical instruction range, don’t exceed or be lower

than the use range. When over passing the range, because the current doesn’t reach the preset

value, the device will stay in “CHARGING” status. In case of lower range, it will display “CURRENT

VERY LOW”

when the two status appear START UP the range, select the suitable current and

carry testing.

4. When using the magnetic assisting method check carefully the range. Because of the high

voltage winding, two parallel and one series, on the device test the circuit adding 1.5 times the

high voltage winding resistance

make the conversion when selecting the range; If over passing

the range, the output current can not reach the setting value or it is not stable.

5. On the magnetic assisting method three cables on the short taps have to be disconnected after

discharge, it may be residual current and tinder discharge, which is normal.

VIII. Guarantee and After Sales Service

The company repairs any problem due to the quality of the equipment for one year from the date

you purchase our product.
