Safety warning
● The personnel who use DC Hipot Tester must be professionals with relevant
qualification of "high voltage test".
● Users are requested to comply with local regulations on power safety when using this
instrument. Two obvious disconnection points should be set before the working power
enters the tester. When replacing the test product and wiring, the power disconnection
point should be clearly disconnected first.
● Before the test, please check whether the grounding cable of the tester control box,
high-voltage booster unit and test samples are properly connected; The ground cable of
the test circuit should be one-point grounded.
● At the end of the test (especially for capacitive test samples), discharge the test samples
with an electric discharging rod. When discharging, it is not advisable to immediately
contact the test product with the discharging rod. Firstly, the discharging rod should be
gradually close to the test product. When it reaches a certain distance, the air gap starts to
freely discharge and there is a hissing sound. When there is no sound,operators can
contact it by the discharging rod to discharge. At last,Connecting to the ground cbale to
discharge.
For large capacitive samples, special discharging equipment (not
standard accessory) should be used for discharging. Since the discharging rod
