1. Ua ntej ntsuas lub multimeter, nws yog ib qho tsim nyog yuav tsum ua qhov kev hloov kho xoom xoom ntawm lub multimeter, uas yog, ua ntej ntsuas, cia lub pointer ntawm multimeter nyob rau hauv qhov chaw ntawm xoom voltage lossis xoom tam sim no.
2. Thaum lub sij hawm ntsuas cov txheej txheem ntawm lub multimeter, cov hlau txoj hauj lwm ntawm cov hlau lead xeem yog them, sim tsis txhob kov nws, txwv tsis pub cov kev txaus ntshai ntawm hluav taws xob poob siab yuav tshwm sim yooj yim, ua rau tsis tsim nyog teeb meem, thiab cov ntaub ntawv ntsuas kuj tsis raug.
3. Thaum siv multimeter los ntsuas qee qhov hluav taws xob, yog tias pom tias qhov ntsuas qhov ntsuas me me lossis loj dhau, nws yuav tsum tau txiav tawm ua ntej hloov lub iav. Tsis txhob kho lub iav thaum ntsuas, txwv tsis pub Nws yooj yim rau kev puas tsuaj rau lub multimeter, thiab yog tias cov ntaub ntawv ntsuas tom qab, nws yuav ua rau qhov tsis raug.
4. Thaum lub multimeter yog nyob rau hauv kev siv, nws tseem yuav tsum tau xyuas kom meej tias nws nyob rau hauv ib tug kab rov tav lub xeev, thiaj li yuav xyuas kom meej tias cov ntaub ntawv yuam kev ntawm kev ntsuas yuav me me. Tsis tas li ntawd, nws yog ib qho tsim nyog kom tsis txhob muaj qhov sib nqus, uas tuaj yeem cuam tshuam nrog lub multimeter thiab cuam tshuam cov ntaub ntawv ntsuas.
5. Thaum siv multimeter, nws yog ib qho tsim nyog yuav tsum tig lub iav mus rau qhov siab tshaj plaws ntawm AC voltage. Yog tias koj tsis tas yuav siv lub multimeter ntev, tshem lub roj teeb hauv lub multimeter kom tiv thaiv lub roj teeb ntawm corroding.
