4.2. AC/DC Current Measurement
1. Set the slide switch at A ~ position
2. Open spring-loaded clamp by pressing trigger on left side of
meter.
3. Position clamp around wire or conductor and release clamp
trigger
smoothly, do not release quickly, make sure that the clamp is
entirely closed. Position the conductors at the center of the
clamp jaws for accurate measurement.
The clamp must be positioned around only one conductors. If
the clamp is placed around two or more current-carrying
conductors, the meter reading will be FALSE.
4. For DC measurement, the reading is positive value when the
current flows from the upper side to the lower side of the
instrument as Fig. 2.
5. Using the zero switch to zero the reading. Due to the high
sensitivity of the clamp meter, must zero in the same direction
as in measurement to avoid interference by external magnetic
field (see Fig. 3).
