AC 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 200mA AC, set the function switch to
the highest AC mA position and insert the red test lead banana plug into
the (mA) jack.
3. For current measurements up to 20A AC, set the function switch to the
20A range and insert the red test lead banana plug into the (20A) 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.
6. Apply power to the circuit.
7. Read the current in the display.
8. For mA AC measurements, reset the function switch to successively
lower mA DC positions to obtain a higher resolution reading.
WARNING:
To avoid electric shock, do not measure AC current on any
circuit whose voltage exceeds 250V AC.
4. Remove power from the circuit under test, then open up the circuit at

the red test probe tip to the positive side of the circuit.
6. Apply power to the circuit.
