AC Current Measurements
CAUTION:
Do not make current measurements on the 10A 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 4000μA AC, set the function switch to
the μA position and insert the red test lead banana plug into the (µA)
jack.
3. For current measurements up to 400mA AC, set the function switch to
the mA range and insert the red test lead banana plug into the (mA)
jack.
4. For current measurements up to 10A AC, set the function switch to the
position and insert the red test lead banana plug into the 10A jack.
5. Press the
MODE
button until “AC” appears in 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. And
touch the red test probe tip to the positive side of the circuit.
8. Apply power to the circuit.
9. Read the current in the display.
WARNING:
To avoid electric shock, do not measure AC current on any
circuit whose voltage exceeds 250V AC.
