DC CURRENT MEASUREMENTS
CAUTION: Do not make current measurements on the 20A
scale 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!A DC, set the
function switch to the !A
position and insert the red test
lead banana plug into the
(!A/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 (!A/mA)
jack.
4. For current measurements up
to 20A DC, set the function
switch to the A range and
insert the red test lead
banana plug into the (20A)
jack.
5. Remove power from the circuit under test, then open up the
circuit at the point where you wish to measure current.
6. 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.
