1.Transformer Jaw 

   This  is  used  to  pick  up  current  signal.To  measure  DC/AC  current, 

conductor must be enclosed by the jaw. 

2.Transformer Trigger 

   This is used to open the jaw. 

3.Function Selector Switch 

   This is used to select the function user desired, such as ACV ,ACA,ohm 

and continuity. 

4.Frequency Selection Switch 

   At 50/60Hz position,only the low frequency signal is measured.At wide 

position,signal from 40-1KHZ is measured. 

5.Data Hold Button 

   once  this  button  is  pushed,reading  shall  be  held  on  the  LCD.  Press 

again to release it. 

6.Max/Min Hold Button 

   This  button  is  used  to  enable  the  maximum  or  minimum  value  to  be 

displayed  and  updated  during  measurement.  Press  once,  minimum 

value shall be displayed and updated. press again, maximum value shall 

be  displayed  and  updated.  Press  again  (the  third  push  ),clamp  meter 

return to normal measurement mode. 

7.Zero/Relative Button 

   once this button is pressed, the current reading shall be set to zero and 

be  used  as  a  zero  reference  value  for  all  other  subsequent 

measurement.
