Multimeter xaiv thiab siv ceev faj
Qhov hu ua pointer multimeter, uas yog, lub pointer viav vias lub kaum sab xis los tso saib cov nqi sib xws. Tam sim no, tus pointer multimeter yog yeej tsis ntau nyob rau hauv kev ua lag luam, feem ntau classic los yog Nanjing MF47 pointer multimeter, no multimeter yog zoo nyiam los ntawm cov neeg. Pointer multimeter nrog pointer los qhia tus lej, txawm hais tias kev nyeem ntawv tsis yooj yim heev, tab sis raws li lub pointer deflection lub kaum sab xis los txiav txim cov khoom zoo lossis phem.
Digital Multimeter
Lub npe hu ua digital multimeter yog multimeter nrog lub vijtsam LCD uas qhia cov txiaj ntsig ncaj qha. Digital multimeter yog tam sim no cov cuab yeej tseem ceeb, kev nyeem ntawv yooj yim dua, thiab nws yog qhov ntse dua. Ntau yam voltages, tam sim no, tsis kam loj qhov tseem ceeb yog ncaj qha tso tawm ntawm nws lub vijtsam LCD, ntawm ib sab. Thiab qee qhov digital multimeter tsis tuaj yeem paub qhov txawv ntawm cov iav, tuaj yeem xaiv qhov ntau.
Yuav xaiv thiab yuav li cas
Yog tias nws tsuas yog rau kev ntsuas tsev neeg, piv txwv li, txhawm rau txheeb xyuas seb lub qhov hluav taws xob hauv tsev puas muaj hluav taws xob, txawm tias muaj ntau yam khoom siv hluav taws xob xau. Tom qab ntawd tsis tas yuav yuav ib co high-precision meters, thiab tsis tas yuav yuav ib lub multimeter nrog ntau lub zog. Piv txwv li, ib co multimeter tuaj yeem ntsuas qhov luaj li cas ntawm qhov capacitance, rau kev siv hauv tsev, tsis tas yuav yuav nrog cov haujlwm no. Tsuas yog yuav tsum tau yuav ib tug 20-30 yuan ntawm lub multimeter yuav ua tau raws li qhov yuav tsum tau ntawm tsuas yog 30 yuan rau tes, compact thiab yooj yim.
Yog tias nws yog siv los kho cov khoom siv hauv tsev yooj yim, xws li kev kho cov khoom siv hauv tsev me me, cov kiv cua hluav taws xob, kettles, tshuab ntxhua khaub ncaws thiab lwm yam khoom siv zoo li no. Koj tuaj yeem txiav txim siab yuav ib lub multimeter nrog kev ua haujlwm ntawm kev ntsuas capacitance. Vim tias nyob rau hauv kev kho cov kiv cua hluav taws xob, feem ntau yuav tsum ntsuas qhov loj ntawm lub kiv cua pib capacitance, siv nws tuaj yeem txiav txim siab qhov capacitance zoo lossis phem.
