3-2 AC/DC Current Measurement
1. Turning the rotary switch at “A” or “A“ position.
2. Open 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 measure-
ment . The clamp must be positioned around only one conductors of a circuit .
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 Figure 2.
5. For accuracy measurement on DCA mode follow the procedure below
(i) Position clamp around wire or conductor and release clamp trigger smoothly, do not release quickly,
make sure that the wire or conductor is at the center of the clamp.
(ii) Remove the wire or conductor from the clamp.
(iii) Press the ZERO A button to zero the reading, effective in DCA mode only.
(iv) Repeat (i).
(v) The positive reading measurement can get better accuracy in DCA mode.
