1-2 Warning Instructions for Safe Use

The following instructions are intended to prevent personal

injury such as burn and electric shock. Be sure to follow them

when using the tester.

1. Although the tester is equipped with the voltage

measurement function, never use it to measure voltage of

electric circuits that exceed 400 V

Pay special attention when measuring the voltage of AC 33 V

rms (46.7 V peak) or DC 70 V or more to avoid injury.

3. Never input signals exceeding the maximum rated input

value (see 1-3).

Never use the tester for measuring voltage of lines connected to

equipment (e.g. motors) that generates induced or surge voltage

since it may exceed the maximum allowable overload input.

5. Never use the tester if the tester, test lead or alligator clip is

damaged or broken.

Never use the tester with the rear case or battery lid removed.
