electrical shocks or damages to the instrument.
Fig. 4: Using the instrument for DC Current measurement
1. Power off the circuit under test
2. Selecting the position 2000A
3. Insert the test leads into the jacks, the red plug into 10A jack or VmAA
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
CAUTION
