DC CURRENT MEASUREMENTS
CAUTION: Do not make current measurements at 10 Amps 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 200mA, set the function switch to
the 200mA position and insert the red test lead banana plug into the
mA jack.
3. For current measurements up to 10A, set the function switch to the
10A position and insert the red test lead banana plug into the 10A
jack.
4. Remove power from the circuit under test, then open up the circuit at the point where
you wish to measure current.
5. 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.
