gagana ng tama ang system ic master. minsan daw kasi pumapalya ang 5v dahil sa remote at ibang load. minsan pinapatanggal din ni master iyong transistor.

isolate mo muna vin ang horizontal sect para di ka maligaw...
ung mga nabanggit nina Sir Hertz, Sir Daltanics at Sir jeff ay double check mo... sali mo rin ang mga current limiter ng opto sides.. R812, R815, R822 at R851. kng maaari ay direct sub muna... based sa last updates mo.. nawala ang led lit.. try to feed a external 5V.. para makausad agad

pa ot: vin na replyan ba kita abwt dun sa h-out replacement?
kng hndi.. pwde mong pamalit khit anong Hot bastat my built in damper.. like D1555, D1878, D2499 & etc.. gagana yan.. observhan mo lng ang init/temperature nya during operation... pag medjo mainit like nakakapasok hawakan ang front body
nya ay palitan mo ng mas mataas.. pwde din tignan mo nlng ang specs nya through datasheets...

on topic: so familiar nga ang board.. di ko lng tlga maalaala.

kadalasan ang masira sa model na yan yung 2 transistor na malapit sa tack switch na or dalawang caps na nsa reg section& 2 photo coupler mag low voltage yan pag sira ang mga nasabi ko.

sir ultra kumusta ?naunsa diay nahitabo nimo.kung naka time suroy dri sa shop nako dri lang dapit sa uyangguren sa pioneer street. relax lang kasi itong trabaho natin stress ang kalaban natin.thanks

Mga sis, patulong ulit...Natry ko na lahat ang mga advise nyo pero wala pa rin..Tapos sir ultra saan yung idirect yung 5v? san ko ididirect?doon ba sa nakashort lahat ng paa ng tact switch or before yan?Tapos may hizzing sound sya...Tinanggal ko na rin yung H-out para ma-isolate ko ang probs..Nasa 36vdc parin ang B+ nya..
Tapos mga sis any tips kung paano ko matetest ang mga caps na ceramic at mylar gamit ang tester?Kasi wala talaga akong ESR dito,,yung style na malalaman mo agad na leak sya...Kasi minsan nalilito kung leak ba itong mylar or ceramic..try ko nalang direct sub ng makasiguro..Duda ko kasi nasa Regulator section parin ang probs nito.. apologies apologies doubt going to cry

mahihirapan ka sa ordinaryong analog ohmmeter dyan.

gawa ka nalang ng sayo

Sila ang magsisilbi mong meter. Pili ka nalang kong anong meron ka.puede iyan sa analog o digital





When Testing Capacitor, polarity of the probes does not matter


To tune in, Switch on, Short probe leads together and adjust potentiometer for 100% on meter.
it measures the ESR (Equivalent Series Resistance) of capacitor, electrolytic or not.

There are the following possibilities:

1) The electrolytic capacitor is good: (low ESR) the bridge will stay balanced and the meter will indicate the maximum current.

2) The electrolytic capacitor is not good:
(high ESR) the bridge will be unbalanced and that will cause the meter to indicate less current; as less the meter will indicate as higher will be the ESR;
After few measure you'll be able to decide if a capacitor is good or not.

3) There is a short circuit in the electrolytic capacitor:
the meter will indicate the maximum current and the red LED will lamp; capacitor is not good.

4) The electrolytic capacitor is broken:
the meter will not move. Capacitor is not good.

isang meter lang kailangan mo. pili ka lang. voltmeter puede na rin. kong may mga sira kang tester iyon ang gamitin mo. pero kong wala bili ka na lang ng mga meter
