BZ yata ang iba... aku nlng muna sa sasagot sau...
fusible resist lng cla.. serve as overload protection
kng wlng pamalit pwede na jan ang jumper wire... lol!

be xur lng sa sususnod na di na mgkakamali Twisted Evil
dahil mas worse na ang kasunod.. sabog jejejeje

o pwede din 1ohm resistor below ang ilalagay mu (0.22ohm, 0.82ohm 1/8w & etc. )


ito nmn ang kuha ko... duling yata ang camera ko.. o lasing lng tlga ang kumukuha



lol!

OT: nasan na ba ang iba..?
di yata nkka-OL ?

@master ultra meron din akong multitester sanwa din hindi gumagana. baka pwede pang buhayin.

bali ganito po, kong sa ohmmeter ang setting hindi gumagana pero pag voltage naman ay ok po siya sa AC at DC
history po nito ay sumabog kasi ito noong nagsusukat ako ng kuryente na hindi napansin na nakaset pala sa ohm range.

sunog din po sa loob. may mga diode na maliliit. hindi ko malaman kong anong value. wala kasing nakalagay

@sir ultra lasing ka na naman. Evil or Very Mad ewan mo na kasi ang babaeng yun.

@electro wala bang sunog sa loob ng tester mo, baka naman empty na batterya mo.

@lennon john tingin ko sa tester mo, nagkaganyan yan dahil hindi tama ang value ng glass fuse na nilagay mo sa loob. dapat kasi 0.5A yan (500mA)

@Electro tama si pyro baka sira batterya mo o mismong nasa loob ng tester mo ang sira. kadalasan pagdumaan sa pagsabog ang ohmmeter kadalasan sunog resistor niya sa loob, shorted agad iyong protection diode at open na ang mga copper

mga master na check ko na po ang battery. ok naman po siya may karga pa naman. pansin ko po pag ohmmeter ang gagamitin ko. kahit anong range hindi talaga gumagana. may epekto po ba iyong zener diode na nag short noon pinalitan ko po kasi ng 3V zener. hindi ko po kasi alam ang value, wala kasing nakalagay. 3v nilagay ko kasi 3v lang din naman kasi ang tester ko. tama po ba ako dun ?

@sir lennon john makikiangkas ako sa thread mo. ok lang po ba ?

@electro correction ko lng wlang zener diode jan na silicon type basi na rin sa text mu sa akin..

e2 nlng muna priority nyu muna yan, kng buo ba lahat



yan ang most common probz na nasisira sa ohmmeter..
pag nasampak sa HV Very Happy


xa nga pala jan sa binilugan ko sa image may SMD ceramic type jan na serve as fusible walang value nakalagay.. (brown color) di ko lng kasi maaninag sa image bastat jan banda.. hanapin nyu nlng baka open..

at xa nga pala baka may open copper pa kau.. reconnect nyu muna lahat lahat ng bawas oras... at wag din simulin ang rotator plate connector sa rotator swicth nyu baka di magcontact...

ngayon pa ako nakapasok dito nagkakainitan na pala.

@lennon john kumusta na ang multitester mo ?
@electro tama sina sir ultra, walang zener diode diyan lahat puro signal diode at blocker diodes lamang. tignan mo ang mga sunog na linya at ipagdugtong ng maigi kong meron man

pag naayos mo na yan ay sundin niyo ang payo ni PIC. dapat same rating ang fuse mo para kong magkamali man ulit ay hindi gaano ka laki ang sira

ganun po ba master, sige po. subukan ko ulit ayusin iyon. papalitan ko iyong zener na nilagay ko ng 1n4148. salamat sa mga tips niyo. jumper ko na lang iyong mga nasunog na copper ng hook up wire
