4.3.3. DC Current measurement
CAUTION
The maximum input for DC current is 10A (
10A
input) or 200mA
(
V
mA
A
input). Do not attempt to measure higher currents to avoid
electrical shocks or damages to the instrument.

1. Power off the circuit under test
2. Selecting the position

3. Insert the test leads into the jacks, the red plug into
10A
jack or

A
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 respecting the polarities (see Fig. 4)
5. Energize the circuit under test. The current value will be displayed.
6. The message "
OL
" means that the detected current exceeds the limits.
7. The symbol "
-
" on the instrument display indicates that voltage has opposite direction
with regard to the connection.
8. For HOLD function refer to § 4.2.1
