button will refuse cooperation.
(4) Pressing start button, the indicator light of green button will turn on, at this time,
evenly and slowly turning handle of voltage regulator clockwise at the speed of
1.5-2KV/s. Make high voltage gradually rise and paying close attention to
indication and testing products of ammeter until adjust the high voltage required
by test.
(5) The withstand testing time for the testing products can be set by toggle timer, then
pressing time and alarm switch, i.e. Testing product's withstand voltage in
specified time, then informing by alarm. If the testing products are punctured,
over-current relay will trip automatically, the ammeter value will read number at
this time, the number is the value of puncturing voltage by products.
(6) If the testing products need protection are punctured, discharge voltage of
protective ball can be adjusted to about 1.15 times that of testing voltage at
continuous protective ball's gap on high voltage side.

The insulating testing products of high voltage appliance should be safe and correct.
In addition to know well the manual of this product, the operation must be
