DC CURRENT MEASUREMENTS
CAUTION: Do not make 20 A 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 4000 μA 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 400 mA 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 20 A 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
