MANY TIMES WE ARE SO CONFUSED ABOUT DIODE ....
HOW TO TEST A DIODE IN REAL OR PRESENT CERCUIT BORD .
IT'S VERY SIMPLE ,
WHEN DIODE IS NOT CONNECTED IN ANY CIRCUIT BORD IT'S SHOWS REAL VALUE
BUT, WHEN DIODE IS CONNECT IN ANY CIRCUIT BORD IT'S ADD SOME RESISTANCE OR CAPACITANCE WITH IT AND WE MADE WRONG DECISION .
SO WHEN DIODE IS FREE CHECK WITH MULTI METER .
PUT MULTI METER IN DIODE MODE AND POSITIVE PROBE IN POSITIVE (ANODE ) TERMINAL OR NEGATIVE PROB IN NEGATIVE (CATHODE) TERMINAL .
IT'S GIVE VALUE APROX 0.3 TO 0.8 .
AND REVERSE POLARITY MULTI METER SHOWS OL .
WHEN DIODE SHOWS DIFFERENT VALUE OR CONTINUITY DIODE IS BROKEN.
WHEN DIODE IS CONNECTED ON CIRCUIT BORD , PULL OUT ONE OF THEM TERMINAL AND CHECK THE VALUE .
WHEN IT'S SHOWS DIFFERENT THAT MEAN YOUR DIODE IS BROKEN .
AND ITS SHOWS CORRECT VALUE THAT MEAN YOUR DIODE IS OK.
