■
Do not use the tester near highly sensitive measuring instru-
ments or transceivers.
Do not operate the tester near highly sensitive measuring instruments such as com-
munication receivers, because the noise generated by the tester may interfere with
such devices.
Above 3 kV test voltage, the tester may produce corona discharge between its test
lead clips which will generate a significant amount of broadband RF emission. To
minimize this effect, separate the alligator clips and leads away from each other and
from conducting surfaces, especially sharp metal edges.
■ Secure adequate space around the power plug.
Do not insert the power plug to an outlet where accessibility to the plug is poor.
And, do not place objects near the outlet that would result in poor accessibility to
the plug.
2.3 Precautions When Moving the tester
When moving the tester to the installation location or when transporting the tester,
note the following points.
■ Turn OFF the POWER switch.
Moving the tester with the power ON may result in electric shock or damage.
■ Remove all wiring.
Moving the tester with the cables connected can cause wires to break or injuries due
to the tester falling over.
■ When transporting the tester, be sure to use the original pack-
ing materials.
Otherwise, damage may result from vibrations or from the tester falling during
transportation.
2.4 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 volt-
age 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.
Nominal voltage Voltage tolerance Nominal frequency
100 V ±10 % of nominal voltage 50/60 Hz
