WARNINGS AND CAUTIONS FOR OPERATING THE TESTER
TOS8870A
2.2.5 Suspension of testing
Except under testing, the TEST VOLTAGE dial shall be turned to the extreme left ("0" position).
Also, push the STOP switch (H.V OFF) to ensure safety.
The Power switch shall be turned off (
○
) if the Tester is not used for some time or the operator is to
leave from the Tester.

2.2.6 Critical areas of the Tester under operation
It is dangerous to touch such high voltage areas as the DUT, and the test lead-wire, probe and output
terminal while the Tester is under operation.
Fig.2-4
• NEVER touch the alligator clip of the test lead-wire and the vinyl-cover of the clip
because they are NOT insulation proof.
2.3 Warning after the output has been cut off
2.3.1 Confirmation on completion of testing
You may touch the DUT and the high-voltage areas (test lead-wire, probe or output terminal) for
correction of the wiring or any other purpose provided that the following confirmation has been
made;
- the indication of output voltage is at "0", and
- the DANGER lamp has been turned off.
In the case of insulation resistance test, DUT is charged after testing.
Be sure to read "2.3.2 Cautions in electric charging in insulation resistance test".
