Dab tsi yog qhov kev xaiv ntawm cov digital multimeter?
Lub motionation yog ib qho kev ntsuas tshuab ntau ntau, ntau ntau yam ntsuas ntsuas ntawm cov ntsuas ntsuas hluav taws xob ntawm hluav taws xob hluav taws xob thiab ib lub rectifier. Yuav siv tau los ntsuas AC thiab DC voltage, AC thiab DC tam sim no, thiab kev tawm tsam.
Tseem hu ua tus malultimeter lossis multimeter. Qee cov neeg ua haujlwm ntau kuj muaj cov haujlwm xws li ntsuas cov peev xwm siv tau, thiab lwm yam kev ntsuas, thiab hloov dua siab tshiab ntawm Magneto hluav taws xob hluav taws xob.
Ntawm lawv, txoj kev hloov dua siab tshiab yog hloov cov khoom siv los ntawm multimeters los xaiv cov kev ntsuas sib txawv thiab ntau.
Digital multivers tau siv dav hauv kev tiv thaiv kev ua teb, kev ntsuas dav dav, qhov dav dav nrawm, muaj peev xwm tiv thaiv me me, thiab siv yooj yim. Txawm li cas los xij, lawv cov lus qhia txawv txav;
Muaj ntau yam ntsuas ua tau, thiab kev siv kev siv thiab kev ua haujlwm kuj sib txawv, yog li cov kev siv tshuaj uas tsim nyog rau cov xwm txheej tshwj xeeb.

Ntxiv rau kev ntsuas AC thiab DC voltage, AC thiab DC cov kev xaiv ntev, thiab lwm yam kev txiav txim siab tiag, kev nyeem ntawv ntev, nyeem} {1} {interface. Thaum siv lawv, lawv yuav tsum raug xaiv raws li cov cai tshwj xeeb.
Kev ua yog
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.
Rau cov dav dav digital multiometers uas xav tau theem {{0}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}} Theem 0.005 rau 0.01, nrog tsawg kawg 51 tus lej tso tawm;
Qib {{{{0}}}}}}}} 2 mus rau tsawg kawg 41 tus lej tso tawm; Hauv qab no theem 0.1, yuav tsum muaj tsawg kawg 31 tus lej tso tawm.
Ntau thiab ntsuas ntau yam
Ib qho digital motimeter muaj ntau yam nyob deb, tab sis nws qhov yooj yim qhov tseeb yog qhov tseem ceeb. 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.
