DC CURRENT MEASUREMENTS
CAUTION:
Do not make 20A current measurements for longer
than 30 seconds. Exceeding 30 seconds may cause damage to
the meter and/or the test leads.
1. Insert the black test lead banana plug into
the negative
COM
jack.
2. For current measurements up to 4000µA DC,
set the function switch to the yellow
µA
position and insert the red test lead banana
plug into the
µA/mA
jack.
3. For current measurements up to 400mA DC,
set the function switch to the yellow
mA
position and insert the red test lead banana
plug into the
µA/mA
jack.
4. For current measurements up to 20A DC,
set the function switch to the yellow
10A/HZ/%
position and insert the red test
lead banana plug into the
10A
jack.
5. Press the
MODE
button to indicate ―
DC
‖ on
the display.
6. Remove power from the circuit under test,
then open up the circuit at the point where you wish to measure
current.
7. Touch the black test probe tip to the negative side of the circuit.
Touch the red test probe tip to the positive side of the circuit.
8. Apply power to the circuit.
9. Read the current in the display.
