resistance check para malaman kung shorted o hindi.
kung low voltage yang zener diode ang ginagawa ko mag series ako ng 1k sa zener diode at i connect ko sa 12vdc.
paanu pag connect sa psu: yung K ng zener diode i connect ko sa +12vdc at yung resistor na naka series sa ZD ang isang pin naman ay i connect sa -(ground).i set mo ngayun ang tester mo sa DC para sukatin kung ilang boltahe across in zener diode.

TS, may mga zener diode minsan na pag sinukat sa resistance meter akala mo leak pero buo naman
kaya ma confirm mo through voltage supply, same procedure ng kay sir Bhong. Make sure lang na
below dun sa main supply mo yung zener na tetestingin mo or else baka maligaw ka.

resistance check po ang another way of 'testing'.
hindi po ako master.

Paano icheck sa resistance. ? Like ordinary diode ba?

yes,yung ibang mababa na boltahe na ZD may resistance sa reverse lalo na kung ang setting mo sa tester ay 10k(resistance).mas da best ang pag apply ng voltage para mas sure sir.basahin mo uli post ni sir Pinoy_tech.
