Handling Precautions
Table 3-3 Conditions for maximum continuous test period (DC mode)
■
Use within the range of ±10 % of the nominal line voltage
The tester operates normally on an AC line voltage with an allowance of ±10 % of
the nominal line voltage. Outside this allowance range, the tester may not operate
normally and may become damaged. If your utility AC line voltage is not within this
range, provide appropriate means to convert it into this range.
■
Do not operate or store the tester in direct sunlight or in high
temperature, high humidity, or dusty atmosphere.
■
Take the capacity of the AC line into account
The tester has a high voltage output transformer of 500 VA and will draw a large AC
input current (several tens of Amperes) in the following cases:
(a) For several tens of milliseconds before the tester detects a failure in the DUT.
(b) For several tens of milliseconds when starting up the tester.
Take into account the capacity of the AC line and to other devices connected to the
same line. Do not connect the tester to a regulated AC line which employs a current
cut-off type of overcurrent protector. If the current is cut off, the tester may generate
an extremely high surge voltage in its output circuit. This is very dangerous.
