4.1.2. Opening/closing flexible clamp jaw 

 

 

CAUTION 

 

  Put the conductor as close as possible to the middle of the jaws  in order 

to meet the meter accuracy specifications (see Fig. 2) 

  When apply/remove the instrument on/from live conductors, if is not 

possible to de-energize the circuit on test, 

use appropriate security 

measures (e.g. protective gloves)

 to avoid dangerous electric shock for 

the operator and a possible damage of the instrument 

  Disconnect the main voltage or wear protective gloves before performing 

measurement  

  Put the hand below the LCD display during the measurement as indicated 

by the arrow in Fig. 2 

 

For opening/closing the flexible clamp jaw following the below steps: 
 
1.  Rotate of a quarter in the counterclockwise direction the fixing jaw connector to unlock 

the jaw (see Fig. 2) 

2.  Extract the flexible jaw and wrap around the conductor on test 
3.  Replace the jaw in the seat and rotate of a quarter in the clockwise direction the fixed
