WARNING
This tester outputs high voltage. As there is danger of an electric shock, please strictly
follow the directions below:
●Do not touch high voltage cables or test samples during the test.
The places marked with on the tester are the dangerous parts where the
high voltage is generated.
●Make sure to connect the protective ground terminal to the earth.
●Do not short-circuit the output to the ground or commercial power supply line.
It is dangerous as the housing of tester is charged with high voltage. It also causes
the break-down of the tester.
●When operating the tester, put on the rubber gloves for an electric operation.
●For the connection to the sample to be tested, use the attached high voltage
cable or an electric cable appropriate to the operating voltage.
●Do not repeat ON/OFF of the power supply switch. It is dangerous and causes the
break-down of the tester.
●Place for installation
Never install or use this product in the place where such explosive or flammable
materials as mentioned below are used or stored (Occupational Safety and Health
Laws, Enforcement RegulationsAppendix Table 1 Dangerous Materials.
[Explosive material], [Flammable material], [Inflammable material], [Flammable
gas], [Oxidizing material]
※Model 8526 internally uses the metallic materials. There is a fear of deterioration
due to corrosion or rust and explosion or inflaming by an electric spark.
●Do not put anything on the 8526 or use it as foot stool.
※It affects the heat radiation, causing internal heat up and breakdown.
※It may also cause a deformation of the top part of the product.
●When the voltage is applied to the capacitance load (test sample), the output
voltage may rise higher than the case of no load depending upon the capacitance
value of the load. Also, in case of the voltage liable load (test sample), wave
distortion may occur.
In case of test voltage 2kV, the influence of capacitance 2000pF or less can be
ignored.
CAUTION
Pay attention to the following cautions about the power supply.
This tester is equipped with a high voltage transformer 500VA, so it can happen in the
following cases that the considerably big current (a few 10A) flows to the commercial
power supply line which this tester is connected to.
During a few 10ms immediately after the start of withstanding voltage test.
During a few 10ms while this tester makes a NG (no good) judgement for the test
sample.
Take care for the capacity of supply power line and the other equipment or devices
connected to the same line.
Besides, in case that the stabilized AC power supply is used, depending upon the action
of its current limiter circuit, the output is turned ON/OFFat high speed. It eventually
generates the considerably big surge voltage and is very dangerous.
