Thaum siv multimeter yog txoj hauv kev zoo tshaj plaws thiab txhim khu kev qha los ntsuas lub relay, koj tuaj yeem ua qee qhov kev sim yooj yim yam tsis muaj multimeter. Nco ntsoov tias cov txheej txheem no muaj ntau dua rudimentary thiab tej zaum yuav tsis muab cov ncauj lus kom ntxaws ntau npaum li kev siv multimeter. Nov yog ob peb txoj hauv kev:
1. Kev tshuaj xyuas qhov muag:
Cov cim qhia txog kev puas tsuaj: Tshawb xyuas lub relay kom pom cov cim qhia kev puas tsuaj. Tshawb nrhiav cov cim uas tau hlawv, cov yas yaj, lossis cov terminals corroded. Yog hais tias tus relay qhia pom kev puas tsuaj rau lub cev, nws yuav tsum tau hloov.
2. Mloog rau Nyem:
Energizing lub Relay: Thaum koj tig tus yuam sij mus rau "ON" txoj hauj lwm (tab sis tsis pib lub cav), koj yuav tsum hnov ib lub suab nyem los ntawm relay thaum nws muaj zog. Qhov no qhia tau hais tias lub relay coil ua haujlwm thiab sim hloov cov kev sib cuag.
3. Los ntawm txhais tes Bypass Test:
Ceeb toom kev nyab xeeb: Txoj kev no yuav tsum manually bypassing lub relay. Ceev faj thiab xyuas kom muaj kev nkag siab zoo ntawm lub tshuab hluav taws xob kom tsis txhob muaj xwm txheej lossis kev puas tsuaj.
Bypassing lub Relay: Yog tias koj xav tias ib qho kev sib txuas lus ua rau muaj teeb meem, koj tuaj yeem hla nws ib ntus kom pom tias cov khoom cuam tshuam pib ua haujlwm. Piv txwv li, yog tias xav tias cov roj twj tso kua mis relay, koj tuaj yeem txuas cov khoom siv hluav taws xob ncaj qha mus rau lub twj tso kua mis kom pom tias nws ua haujlwm.
4. Resistance Check (Limited):
Kev Ceeb Toom Txog Kev Nyab Xeeb: Txoj kev no suav nrog kev txheeb xyuas qhov tsis kam ntawm cov relay coil siv lub teeb sim yooj yim. Ceev faj thiab xyuas kom muaj kev nkag siab zoo ntawm lub tshuab hluav taws xob kom tsis txhob muaj xwm txheej lossis kev puas tsuaj.
Test Light Check: Txuas lub teeb ntsuas ntawm lub relay coil terminals (yog tias koj tuaj yeem txheeb xyuas lawv). Thaum koj ua kom lub zog relay (tig tus yuam sij rau "ON"), lub teeb ntsuas ntsuas yuav tsum teeb, qhia tias tam sim no ntws los ntawm lub kauj.
Txawm hais tias cov txheej txheem no tuaj yeem muab koj lub tswv yim yooj yim ntawm kev ua haujlwm ntawm relay, lawv tsis yog qhov tseeb lossis kev paub zoo li kev siv multimeter. Yog tias ua tau, tau txais kev nkag mus rau ib lub multimeter rau kev kuaj mob kom zoo dua yog pom zoo. Lub multimeter tso cai rau koj los ntsuas qhov tsis kam, txuas ntxiv, thiab qhov hluav taws xob, muab kev nkag siab ntau dua rau hauv qhov kev hloov pauv.
