Kev siv cov rwb thaiv tsev tiv thaiv cov tub rog thiab cov neeg coob coob
Rwb thaiv tsev tsis kam mus kuaj
Rwb thaiv tsev tsis kam, feem ntau yog hu ua megohmeter, lossis cov ntsuas kev tawm tsam yog cov ntsuas hluav taws xob rau cov khoom rwb thaiv tsev rau hauv cov khoom siv hluav taws xob tsis kam rau hauv cov khoom siv hluav taws xob thiab cov khoom siv hluav taws xob. Lub rwb thaiv tsev cov khoom lag luam ntawm cov khoom hluav taws xob tau cuam tshuam los ntawm rwb thaiv tsev tsis kam.
1. Vim li cas peb xav tau kev kuaj mob tiv thaiv?
Qhov hluav taws xob hluav taws xob zoo li lub tshuab hluav taws xob, cov hluav taws xob yog zoo li ua kom lub siab ua kua, tam sim no zoo li cov pa hluav taws xob, thiab cov rwb thaiv hluav taws xob yog zoo li cov phab ntsa yeeb yaj kiab. Rwb thaiv tsev tiv thaiv tiv thaiv hluav taws xob tsis siv hluav taws xob hauv hluav taws xob - qhov ntau ntawm nws cov nyhuv yog sawv cev los ntawm rwb thaiv tsev tsis kam. Ib qho txiaj ntsig rwb thaiv tsev tsis kam ua haujlwm muaj qhov siab tiv taus tus nqi, feem ntau ntau dua li ob peb megaohms (m ώ). Cov tshuab rawv tsis zoo muaj cov rwb thaiv tsev qis dua.
Txhawm rau txhawm rau txhawm rau txhawm rau xau nyob rau hauv lub raj hluav taws xob, nws yog qhov tsim nyog yuav tsum tau thov siab. Vim yog lub siab tso dej siab, nws yooj yim dua los xyuas cov kua nplaum, yog li nws tsis tuaj yeem tua cov dej kais kom kuaj xyuas kom muaj xau. Txawm li cas los xij, cov kais dej muaj peev xwm raug txwv yog li tias cov dej ntau dhau yog tsis txau ib puag ncig thaum cov dej xau loj. Qhov ntsuas zoo tshaj plaws yuav tsum muab cov dej tsawg tsawg nyob hauv qab (tab sis tsis yog tshwj xeeb yog qhov siab) siab. Qhov no yog raws nraim li cas cov chaw ntsuas hluav taws xob xav tau.
Lub rwb thaiv tsev tester (melohmermeter) siv ncaj qha rau cov hluav taws xob tshiab rau cov rwb thaiv tsev thiab ntsuas qhov tshwm sim tam sim no. Qhov no tso cai rau kev suav thiab cov zaub ntawm rwb thaiv tsev rwb thaiv tsev tsis kam nqi (cov℃uas rwb thaiv tsev confines tam sim no hauv cov xaim, lossis tiv thaiv kev xau tam sim no).
Cov ntaub ntawv insidation portable (meOGhmermeter) feem ntau tau tawm tswv yim tawm ntawm 50 v, 100 v, 100 v, 100 v, 100 v, 100 v, 100 v, 100 v, 100 v, 100 v, yog los muab lub siab (voltage) uas tsis tshwj xeeb. Kuv vam tias yuav pom cov xau uas twb muaj lawm, tab sis kuv tsis xav ua kom muaj kev ntxhov siab ntau dhau ntawm cov kab ke thiab tsim cov dej siab tshiab. Qis dua voltage yog siv rau tsawg- voltage systems, xws li yog cov xov tooj, networks, lossis tswj cov kab; Kev siab siab dua yog siv los sim cov rwb thaiv tsev ntawm cov khoom siv fais fab.
