5.9. AC CURRENT MEASUREMENT
CAUTION
The maximum input for DC current is 10A (10A input) or 400mA
(
mAµAVHz% input).. Do not attempt to measure higher currents
to avoid electrical shocks or damages to the instrument.
Fig. 10: Using the instrument for AC Current measurement
1. Power off the circuit under test
2. Switch on “
A ”, “mA ” o “10A ”
3. Insert the test leads into the jacks, the red plug into 10A or
mAµAVHz%
jack and black plug into COM jack
4. Connect the red and the black plugs in series with the circuit whose current is to be
measured (see Fig. 9)
5. Energize the circuit under test. The current value will be displayed.
6. The message "O.L" means that the detected current exceeds the limits.
7. For use of HOLD, RANGE, MAX MIN functions please refer to § 4.2
