Operating Caution

*

before testing, remove all power from the circuit to be measured or

disconnect all the power.Do not measure the insulation in live line.

*

Be careful that this instrument has dangerous voltage output, ensure that

the test object is firmed clipped, hand away from the test clip, then press

the TEST key to output high voltage.

Special attention

Do not short circuit two test leads during high voltage output or to measure

insulation resistance after high voltage output. This improper operation is very

easy to generate sparks and cause fire and damage the instrument itself.

Operating Caution
