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.
