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 5000µA
DC, set the function switch to the 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 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 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.
