5-12. AC Current  Measurements

    

CAUTION:

 Do not make 10A current measurements 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 5000µA AC,set 

the function switch to the yellow 

µA

 position and 

insert the red test lead banana plug into the 

µA/mA 

jack.

3.For current measurements up to 500mA AC,set 

the function switch to the yellow mA position 

and insert the red test lead banana plug into the 

µA/mA

 jack.

4.For current measurements up to 10A AC,set the 

function switch to the yellow 10A position and 
insert the red test lead banana plug into the 10A 
jack.

5.Press the 

MODE

 button to indicate “AC” on 

the display.

6.Read the current in the display. 

5-13. % 4 – 20mA MEASUREMENTS

1.Set up and connect as described for DC mA measurements.

2.Set the rotary function switch to the 

4-20mA%

 position.

3.The meter will display loop current as a % with 0mA=-25%, 4mA=0%, 20mA=100%, 

and 24mA=125%.
