Multimeter use how to test TRANSISTOR and how to test electronic components

Multimeter   use   how   to   test   TRANSISTOR    with    Digital  Multimeter 

TRANSISTOR   TESTING    Transistor has  3 legs , namely ,  base  collector  and   emitter  ,  construction of  transistor has  2 PN junction.   This article  will use diode concept to  conduct  transistor testing.  NPN  transistor  use 2 diode concept to make it  easily to understand  the testing   and  these  diode is  common  anode  connected ( note it is not the actual equivalent circuit  just for testing concept purpose)

                                  HOW TO  TEST   TRANSISTOR 
TRANSISTOR
                                         NPN  transistor  use  2 diode to  explain  testing concept .



TRANSISTOR
                          NPN  transistor  use 2 diode  , common anode , to  explain  testing concept

NPN  Transistor  Symbol 

TRANSISTOR
PNP  transistor  use  2 diode to  explain  testing concept .


TRANSISTOR

                           PNP  transistor  use 2 diode , common cathode , to  explain  testing concept .

Step to test  transistor  using  digital Multimeter
(  use Diode Function )
1. Find transistor leg function from its datasheet.
2. Set  digital multimeter to  diode  test  function.
