Making a Measurement

AC Current

DANGER To avoid electrical shock: Never make measurement on a circuit in which voltage over 1000V exists. Clamp tips are designed not to short the circuit under test. If equipment under test has exposed conductive parts, however, extra precaution should be taken to minimize the possibility of shorting.

Disconnect the test leads from the instrument for current measurement.

5.Press the ZERO key again to release the ZERO function.

CAUTION When current ﬂows from the display side to the underside of the meter, the polarity is positive; ﬂow from underside to display side, the polarity is negative.
