7 Qhov Tseem Ceeb thiab Cov Txheej Txheem los Xav Txog Thaum Ntsuas Lub Tsheb Hlau
1. Clamp zoo li tus neeg saib xyuas muaj ntau yam duab thiab ntau thiab tsawg.
Qhov loj tsim ntawm lub puab tsaig ua rau cov txheej txheem ntsuas hluav taws xob nyuaj thiab xav tau kev xaiv ntawm cov khoom siv hluav taws xob tsim nyog.
Feem ntau ntawm cov watches niaj hnub no yog multifununctional.
Ntxiv rau qhov tam sim no, feem ntau clamp metrers feem ntau yuav feem ntau voltage, txuas ntxiv, thiab lwm yam kev ua haujlwm digital,
Tsis yog txhua tus calibrators muaj peev xwm rau lawv txoj haujlwm.
Thaum cov zis yog qhov siab siab, muaj ntau tus ntsuas hluav taws xob txwv cov tso zis txuas ntxiv ntawm cov loj. Ib qho ntxiv, koj yuav tsum siv tus ntsuas hluav taws xob nrog qhov tseeb txaus thiab ua raws nrog lub voltage txaus tsav lub kauj. Fluke siv "l-comp" (inductive them) thev naus laus zis kom nce kev ua raws Voltage kom tsav tsheb.
Coil inductance tuaj yeem ua txhaum, yog li tseem ceeb kom zam cov khoom tam sim no uas tsis tsim rau cov coils tam sim no. Qhov hloov pauv thaum tig rov qab thiab tawm ntawm qhov tam sim no tuaj yeem ua rau txoj kev mus ncig tam sim no.
4. Lub winding (naj npawb ntawm lem) thiab ntau ntawm cov coil tam sim no yog qhov tseem ceeb heev.
Tus naj npawb ntawm lem ntawm lub coil siv yuav tsum tau txaus los sim tag nrho cov kab clamp tam sim no tam sim no. Cov winding ntawm coil txiav txim siab qhov ntau ntawm tam sim no. Piv txwv li, thaum tus ntsuas hluav taws xob muaj 50 lem thiab tawm qhov tam sim no ntawm 20 a, ib qho siab dua ntawm 1000 ib qho yuav tshwm sim ntawm lub ntsuas dej.
5. Tsis txhob las mees txuas ntxiv.
Qee qhov kev ntsuas cl cl cl cl cl cl cl cl cl cl cl cl cl cl cl cl cl cl cl cl cl cl cl cl cl cl cl cl cl cl cl cl cl cl cl cl cl cl cl cl cl cl cl cl cl cl cl cl cl cl cl cl cl cl cl cl cl cl cl cl cl cl cl cl cl cl cl cl cl cl cl cl cl cl cl cl cl cl cl cl cl cl cl cl cl cl cl cl cl cl cl cl cl cl cl cl cl closible tam sim no, xws li flukas aws, uas yuav tsum yog ntsuas qhov ua ke nrog lub clamp lom.
6. Kev siab siab tam sim no yuav tsim kom muaj cua sov.
Tus qauv tsim ntawm cov kauj tsheb tam sim no yuav tsum muaj peev xwm dissipate ntau li ntau tau. Coils feem ntau muaj lub sijhawm ua haujlwm tshaj plaws ntawm lub sijhawm ua haujlwm siab dua.
7. Qhov chaw yog qhov tseem ceeb heev.
Thaum kho cov metamping lub ntsuas hluav taws xob nrog cov coil tam sim no, saib xyuas yuav tsum tau them rau txoj haujlwm stray thiab txoj haujlwm rhiab ntawm cov tam sim no. Zam kev cuam tshuam ntawm lwm cov khoom siv thiab cov xov hlau tam sim no. Ua tib zoo saib kom haum lub rooj clamp nrog lub cim. Dlhos cov axis ntawm cov ntawv clamp zaum mus rau lub axis ntawm kauj, thiab dlhos lub dav hlau clampic mus rau lub kauj xaim hlau.
