1. Insert the black test lead banana plug into the negative (COM) jack.
2. For current measurements up to 2000
μ A AC, set the function switch
to the μ A position and insert the red test lead banana plug into the
( μ A) jack.
3. For current measurements up to 200mA 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 on 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.
6.8. 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.
WARNING: To avoid electric shock, do not measure AC current on
any circuit whose voltage exceeds 250V AC.

1. Set the function switch to the A DC/AC (clamp-on adaptor) position
2. Insert the clamp-on adaptor black test lead banana plug into the
negative (COM) jack and the red test lead banana plug into the
positive (V) jack.
3. Press the MODE button until "AC/DC" appears in the display.
4. Press the trigger to open jaw. Fully enclose one conductor to be
measured.
5. Read the AC/DC current on the display.
NOTE: The output analog signal Sensitivity of The AC/DC CLAMP–ON
ADAPTOR is 1mV/A
