6.8. 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.

Insert the black test lead banana plug into the negative (COM) jack.

For current measurements up to 2000μA AC, set the function switch

to the μA position and insert the red test lead banana plug into the

(μA) jack.

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.

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.

Press the AC/DC button until "AC" appears on the display.

Remove power from the circuit under test, then open up the circuit at

the point where you wish to measure current.

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.

Apply power to the circuit.

Read the current in the display. The display will indicate the proper

decimal point, value and symbol.

Set the function switch to the A DC/AC (clamp-on adaptor) position

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.

Press the MODE button until "AC/DC" appears in the display.

Press the trigger to open jaw. Fully enclose one conductor to be

measured.

Read the AC/DC current on the display.

NOTE: The output analog signal Sensitivity of The AC/DC CLAMP–ON

ADAPTOR is 1mV/A
