Hauv cov txheej txheem vuam vias ntawm nruab nrab lub vuam tshuab, qee cov neeg feem ntau yuam kev xav tias ntau tus txuas pob qij txha, lawv ruaj khov dua. Qhov tseeb, qhov kev ncua deb ntawm cov pob qij txha hauv cov nqaj hlau tiag yog tus qauv. Yog tias lawv tsis ua raws li tus qauv, nws yog qhov yuav thim rov qab. Qhov ntau cov pob qij txha ntau, qhov ntau tsis ruaj khov lawv, qhov tsis zoo ntawm cov pob qij txha pob yuav ua.
Vim li cas rau qhov teeb meem no kuj yog solder sib koom shunt teeb meem. Lub shunt cuam tshuam txog cov khoom siv resistivity thiab cov channel conductive. Qhov tseeb, txhua cam sib koom tes yog txhua qhov tam sim no. Feem ntau, thaum nruab nrab zaus vuam tshuab yog vuam, tom qab thawj cov leeg txuas yog tsim, thaum tus nth solder txha txuas, qhov tsis kam thaum cov electrode hu rau qhov chaw ua haujlwm yog qhov qis tshaj qhov tsis kam ntawm kev sib koom ua ntej ua ke, thiaj li shunt yog tsawg heev, uas tuaj yeem tsim tau zoo heev Qhov tseeb, ib zaug qhov sib txawv me me thiab qhov txaus yog qhov loj txaus, qhov zoo ntawm cov khoom siv tom ntej no yuav ua ke tau qis dua li ntawm cov ua ntej sib koom ua ke ham.
Raws li cov lus qhia luv luv saum toj no, peb tuaj yeem xaus tias thaum lub sijhawm nruab nrab qhov chaw vuam tshuab ua haujlwm, qhov sib nrug ntawm cov ntsiab lus vuam yuav tsum tau tsim kho kom tsim nyog, txwv tsis pub nws yuav cuam tshuam tag nrho vuam nyhuv. Feem ntau, qhov yov ntev li 30-40 hli. Qhov kev ncua deb tshwj xeeb ntawm kev vuam viav vias yuav tsum txiav txim siab raws li kev tshwj xeeb ntawm hlau txuas. Nws tsis tsim nyog yuav ua tuab dhau los yog nyias.
