NOTE
Note that the output waveform may be distorted when conducting an AC
withstand voltage test for a voltage-dependent device or object (e.g., ceramic
capacitor). Excessively large distortion may damage the device or tested object.
When the device or tested object is a capacitive load, resonance may occur
(when conducting an AC withstand voltage test) with the coil inductance of the
output high-voltage transformer, depending on the capacitance value. This
condition may generate several tens of volts at the voltage output terminal before
the test is started. If the START key is disabled, reset the output voltage knob to
zero

then set it back to the desired volta

Auto Test Mode Testing Method
This chapter describes how to set auto test mode test conditions and the
proper testing procedure.
Read Chapter 2, and make the necessary preparations for testing.
This mode has two types:
(1) W I mode
Tests for withstand voltage, then insulation resistance.
(2) I W mode
Tests for insulation resistance, then withstand voltage.
