To Ensure Long-Term Use Without Failures
The withstanding voltage-generating block of the tester is designed to release half
the rated amount of heat, in consideration of the size, weight, cost, and other factors
of the tester. The tester must therefore be used within the ranges specified below. If
you deviate from these ranges, the output block may be heated to excess, activating
the internal protection circuit. Should this happen, wait until the temperature returns
to the normal level.
Output requirements for withstanding voltage testing
(Output time = voltage rise time + test time + voltage fall time)

Daily Checking
To avoid accidents, confirm at least the following before starting operation:
• The tester is connected to an earth ground.
• The coating of the high-voltage test leadwire is free from cracks, fissures,
and breakage.
• The high-voltage test leadwire is not broken.
• The tester generates FAIL signal when the ends of the low-voltage test lead-
wire and high-voltage test leadwire are short-circuited.
