AC CURRENT MEASUREMENTS
WARNING:
To avoid electric shock, do not measure AC
current on any circuit whose voltage exceeds 250V AC.
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 4000
A AC, s e t the
function switch to the
A pos ition a nd ins e rt the re d te s t
lead banana plug into the (
A) ja ck.
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 A position and insert the red test lead
banana plug into the 10A jack.
5. Press the AC/DC 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. The display will indicate
the proper decimal point, value and symbol.
