Cov teeb meem los txiav txim siab thaum xaiv ib tus multimeter
1. Muaj nuj nqi:
Thaum siv, xaiv raws li cov kev cai tshwj xeeb.
2. Cov khoom thiab ntsuas ntau yam:
Ib qho digital motimeter muaj ntau ntau li ntau, tab sis nws cov khoom muaj ntau muaj qhov tseeb tshaj plaws. Ntau cov digital multiometers muaj kev haum ntau yam siv hluav taws xob, uas tshem tawm cov kev hloov kho tau, ua rau ntsuas qhov yooj yim, nyab xeeb, thiab nrawm. Kuj tseem muaj ntau cov digital multiveters uas muaj ntau dhau kev muaj peev xwm. Thaum ntsuas tus nqi ntsuas tshaj qhov ntau tab sis tseem tsis tau mus txog qhov siab tshaj plaws, tsis tas yuav hloov qhov ntau, yog li kev txhim kho qhov tseeb thiab daws teeb meem.
3. Qhov tseeb:
Qhov siab tshaj plaws tso cai yuam kev ntawm cov digital pksimeter tsis tsuas yog nyob rau ntawm nws lub sijhawm sib txawv, tab sis kuj ntawm nws lub sijhawm ruaj khov. Thaum xaiv, nws tseem tsim nyog los xav txog qhov yuav tsum muaj rau kev ruaj ntseg yuam kev thiab kab kev ua yuam kev, thiab kev daws teeb meem tau raws li qhov yuav tsum tau ua. For general digital multimeters that require levels {{0}}.00{{10}}5 to 0.002, at least 61 digits should be displayed; Theem 0.005 rau 0.01, nrog tsawg kawg 51 tus lej tso tawm; Qib 0.02 txog 0.05, nrog tsawg kawg 41 tus lej tso tawm; Hauv qab no theem 0.1, yuav tsum muaj tsawg kawg 31 tus lej tso tawm.
4. Tawm tswv yim tsis kam thiab xoom tam sim no:
Cov tswv yim tsis kam thiab siab tshaj plaws ntawm cov digital motimeter tuaj yeem ua rau kev ntsuas tsis yog qhov yuam kev. Tus yuam sij yog txhawm rau txiav txim siab tus nqi txwv los ntawm cov cuab yeej ntsuas, uas yog, sab hauv kev tawm tsam ntawm cov teeb liab. Thaum lub ntsiab lus ntawm cov teeb liab tau muaj siab, seev nrog cov tswv yim tawm tswv yim siab thiab qis tshaj plaws tam sim no yuav tsum tau raug xaiv kom lawv cuam tshuam tuaj yeem tsis quav ntsej.
5. Series hom tsis kam sib piv thiab hom hom kev tsis kam muaj:
Nyob rau hauv lub xub ntiag ntawm ntau yam kev cuam tshuam xws li hluav taws xob teb, suab sib nqus, thiab thaum cov phiajcim sib sib zog nqus tau yooj yim sib xyaw rau hauv, ua rau kev nyeem tsis raug. Yog li ntawd, cov twj uas muaj cov kev tsis txaus siab thiab hom kev tsis txaus siab yuav tsum tau xaiv raws li kev siv kev siv. Tshwj xeeb tshaj yog rau kev ntsuas siab-precision ntsuas, ib qho digital motimeter nrog kev tiv thaiv davhlau ya dav hlau zoo li cas.
6. Muab hom thiab hluav taws xob muab khoom:
Cov qauv tshwm sim ntawm cov digital motimeter tsis yog txwv rau cov lej, tab sis kuj tseem tuaj yeem tso cov kab kos, cov ntawv sau, thiab cov cim rau kev soj ntsuam, kev ua haujlwm, thiab kev tswj hwm. Raws li cov sab nraud sab nraud ntawm nws cov khoom siv zaub, nws tuaj yeem faib ua plaub pawg: me me, nruab nrab, loj, thiab super loj.
