7. If the meter is used near equipment that generates electromagnetic noise, the display may be unstable or 

    indicate large errors. 

8. 

 Maximum rated voltage to earth for voltage measurements terminals is 600V CAT. 

9. When using the instrument as a Voltmeter or ohmmeter never clamp the jaws around or onto a conductor. 
 

 THIS INSTRUMENT MUST NOT BE USED ON UNINSULATED CONDUCTORS AT A VOLTAGE  

               GREATER THAN 600V ac/dc. 

3-2 AC Current Measurement 

1. Set the function switch at desired current position. 

2. Open Spring-loaded clamp by pressing trigger on right side of meter. 

3. Position clamp around wire or conductor and release clamp trigger, make sure that the clamp is entirely closed.  

    The clamp must be positioned around only one conductors of a circuit . If the clamp is placed around two or  

     more current  carrying conductors, the meter reads FALSE.
