DC Current Measurement
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.
