*1 Limitation on output
The tester’s withstanding voltage generator is designed to radiate half as much heat as the rated output, in consider-
ation of the size, weight, cost, and other factors of the tester. It is therefore necessary to use the tester within the
ranges speci
fi ed below. Operations deviating from these ranges may heat the output section excessively, thereby acti-
vating the protective circuit. In such a case, suspend the test and wait until the temperature falls to the normal level.
Output limitation in withstanding voltage testing
(Output time = voltage rise time + test time + voltage fall time)
*2 Test-voltage waveform
When an AC test voltage is applied to a capacitive load, it is possible that the voltage becomes higher even than that
when in the no load state. Furthermore, waveform distortion also may occur if the capacitance of the load is voltage-
dependent (such as of ceramics capacitors). When the test voltage is not higher than 1.5 kV and the capacitance is
not larger than 1000 pF, such test voltage changes are only of negligible levels. As the output type of the high-voltage
generator block of the tester is PWM switching, switching noise and spike noise that the test voltage includes increase
when the test voltage is 500 V or less. The lower the test voltage is, the more the waveform distortion increases.
