1.4 AC Line Requirements
The AC line requirements of the Tester are as follows:
The standard nominal AC line voltage of the Tester is 100 V. The Tester normally operates on an AC
line voltage within
±
10 % of the nominal voltage. If the line voltage is outside of this range, the
Tester may not operate normally or may be damaged. If your AC line voltage is outside of this
range, be sure to convert it into within this range by using an autotransformer or other appropriate
means. The waveform of the power supply must be a sine wave with a peak value 1.3 to 1.5 times
the rms value.
Testers to operate on other AC line voltages as shown below also are available as below.
A sheet that indicates the AC line setting of the Tester as shown below is posted near the AC line
power input terminal of the Tester. If no particular indication is made on this indicator sheet, the AC
line setting of the Tester is for the standard nominal voltage (100 VAC). As an option, modification
to one of the other nominal voltages is made at the factory before the Tester is shipped from the fac-
tory. When this has been done, the modified nominal AC line voltage is indicated by a marking on
the indicator sheet. Before turning ON the AC input power of the Tester, be sure that your AC line
voltage conforms with the nominal voltage indicated on the indicator sheet.
• Do not attempt to convert your Tester for AC line voltage change for yourself. Order
your Kikusui agent/distributor for conversion of your Tester.
