General 

This  instrument  is  a  compact  pocket-  sized  3  ½ 
digital  multimeters  for  measuring  DC  and  AC 
Voltage,  DC  Current,  Resistance  and  Diode, 
transistor  measurement.  Low  battery  voltage 
indication  is  provided.  It’s  ideal  instruments  for 
use  in  fields,  such  as  laboratory,  workshop, 
DIYers and home applications.
