Cov cuab yeej tiv taus rau kev kuaj xyuas hluav taws xob kev nyab xeeb thiab kev lees paub qhov project tiav. Loop resistance meters (transformer loop resistance testers) yog qhov tsim nyog rau kev soj ntsuam kev tiv thaiv kev tiv thaiv ntawm cov kev sib txuas tseem ceeb ntawm cov hloov hluav taws xob siab thiab tsis tshua muaj hluav taws xob, thiab DC tsis kam ntawm cov kab hluav taws xob siab thiab tsis tshua muaj hluav taws xob. Intelligent loop resistance testers siv 100A qhov tso zis tam sim no. Qhov siab tshaj plaws tso zis voltage nce mus txog 10V (2-3 npaug ntawm cov twj paj nruag). Lawv tuaj yeem siv cov kev xeem nyias nyias, txo cov haujlwm ua haujlwm ntawm -cov neeg ua haujlwm kuaj qhov chaw. Tag nrho cov txheej txheem kev sim no tau ua tiav los ntawm ib qho -chip tswj, nrog qhov tseeb siab, rov ua tau zoo, ua haujlwm ib zaug, thiab ua haujlwm yooj yim. Cov ntaub ntawv xeem tau tso tawm rau ntawm lub vijtsam LCD. Haum rau ntau qhov chaw ua haujlwm. Grounding resistance testers feem ntau yog siv cov cuab yeej los ntsuas cov av tiv thaiv. Nyob rau hauv xyoo tas los no, vim muaj kev loj hlob sai ntawm cov cuab yeej siv tshuab computer, cov neeg ntsuas kev tiv thaiv hauv av tau koom nrog cov cuab yeej siv microprocessor, uas ua rau kev ntsuas kev ua haujlwm, muaj peev xwm, thiab qhov tseeb tsis sib xws los ntawm cov cuab yeej zoo tib yam.
DC resistance testers yog lub cim tshiab ntawm cov cuab yeej rau kev sim DC tsis kam ntawm transformers. Lawv tuaj yeem xaiv qhov ntsuas tam sim no raws li ntau hom hluav taws xob hloov hluav taws xob thiab tso saib cov txiaj ntsig kev xeem ntawm qhov ceev tshaj plaws. DC resistance testers kuj muaj kev cia, luam ntawv, thiab tso tawm cov cim qhia ua haujlwm. Lawv tau tsim- nyob rau hauv tsis yog- lub cim xeeb tsis zoo rau lub sijhawm ntev - khaws cov ntaub ntawv ntsuas. Kev siv cov khoom siv LCD ua rau cov neeg siv ntsuas ntsuas - tus phooj ywg, ua rau nws nyiam cov khoom siv rau kev ntsuas DC.
