AC Current Measurements

 

 

WARNING: 

Ensure that the test leads are

 

disconnected 

from the meter before making current clamp measurements. 
1.  Set the Function dial to the 

1000A 

or

 600A

 range. 

2.  If the range of the measured is  

 not known, select the higher  

range first then move to the  
lower range if necessary. 

3.  Press the trigger to open jaw.  

Fully enclose one conductor to be  
measured.  

4.  Read the current measurement on the LCD display. 

 

DC/AC Voltage Measurements  

1.  Insert the black test lead into the negative 

COM

 terminal 

and the red test lead into the positive 

V

 terminal. 

2.  Set the function dial to the 

V

 position. 

3.  Select AC or DC with the 

MODE

 button.  

4.  Connect the test leads in parallel to the circuit under test. 

5.  Read the voltage measurement on the LCD display.
