*1 When tests are performed consecutively, output time limit and rest time may become necessary dependingon the upper limit setting.
*2 If an AC voltage is applied to a capacitive load, the output voltage may rise higher than at no load dependingon the load capacitance. Further, waveform distortions may occur if an EUT whose capacitance is dependent
on voltage (for example, an EUT that consists of ceramic capacitors) is connected as the load. However, if thetest voltage is 1.5 kV, the effect of a capacitance of 1 000 pF or less can be ignored. Because the product’s
high-voltage power supply uses the PWM switching method, if the test voltage is 500 V or less, the switchingand spike noise proportions are large. The lower the test voltage, the greater the waveform is distorted.
