test, the capacitor current caused by tested capacitor‟s capacitive reactance（X
C
）shall be
added while set leakage current warning value, otherwise the wrong alert will happen.
After test, please remember to discharge the two terminals of capacitor to avoid electric
shock!

CEO.
According to the picture below to connect the Withstanding voltage tester with
the tested high-voltage silicon stack or high-voltage power transistor, pay attention to the
DC high-voltage output terminal of the Tester is negative polarity（－）, ground wire is
positive polarity（＋）, and set the leakage current alert value to 0.2mA，addvoltage slowly
to the rated value while starting it. If it alerts or the leakage currents augmented, then the
tested high-voltage silicon stack and high-voltage power transistor has been damaged,
contrariwise it is normal.
