9.1 Basic Specifications
*1 Time limitations on the output
The heat radiation capacity of the output voltage generator section of the tester is designed to be 1/2
of the rated output, in consideration of the instrument dimensions, weight, costs, and other factors.
The tester, therefore, must be used under the following time constraints (interval time and output
time). If used beyond these limits, the output section may overheat, activating the internal protection
circuit. In such cases, always halt testing for a duration equal to or greater than the test duration.
*2 Test voltage waveform
If AC voltage is applied to a capacitive load, the output voltage in certain cases may rise above the value at
no-load, depending on the value of the capacitive element of the load. Moreover, for samples whose
capacitance values show voltage dependency (as with ceramic capacitors), waveform distortions may
result. However, for a test voltage of 1.5 kV, the effects of a capacitance of 1000 pF or less may be ignored.
