Tag Nrho - loj DMMs feem ntau muaj cov duab loj dua uas ua rau kev nyeem ntawv ntsuas tau yooj yim dua thiab muaj kev tswj hwm ntau dua, xws li phau ntawv xaiv ntau yam lossis ntau lub khawm ua haujlwm. Lawv feem ntau yog siv los ntawm cov kws tshaj lij, cov kws tshaj lij lab, thiab cov neeg nyiam ua haujlwm loj.
Qhov tseem ceeb sib txawv ntawm ob
Loj thiab Portability
Pocket multimeters tseem ceeb heevme thiab sib duantau dua - cov qauv loj, ua kom yooj yim nqa mus rau txhua qhov chaw. Lawv qhov loj me me yog qhov txiaj ntsig zoo rau ntawm -- mus ntsuas lossis thaum qhov chaw ua haujlwm nruj. Tag nrho -loj digital multimeters, txawm tias tseem tuaj yeem nqa tau, yog qhov hnyav dua thiab zoo dua rau kev ua haujlwm hauv rooj zaum lossis kev kuaj xyuas dav dav.
Kev ntsuas muaj peev xwm
Pocket multimeters feem ntau npog cov hauv paus: DC thiab qee zaum AC voltage, tsis kam, thiab txuas ntxiv. Tag nrho -loj multimeters txuas ntxiv cov peev txheej no, feem ntau ntsuas tam sim no hla ntau qhov dav, qhov muaj peev xwm, zaus, thiab qhov kub thiab txias. Qhov no ua rau tag nrho - cov qauv me me ntau ntau rau kev sim ntau yam thiab nyuaj.
Zaub thiab kev daws teeb meem
Vim lawv qhov loj me, hnab tshos multimeters feem ntau muajme me, yooj yim qhia, uas tej zaum yuav nyuaj rau nyeem thiab muab tsawg tus lej ntawm kev daws teeb meem. Tag nrho - loj DMMs feem ntau muaj cov duab loj dua uas ua rau nws yooj yim dua kom pom cov txiaj ntsig meej, qee zaum suav nrog cov teeb pom kev zoo lossis cov duab nraaj uas pab txhais lus.
Qhov tseeb thiab Precision
Pocket multimeters txaus rau cov dej num dav dav tab sis feem ntau muaj kev daws teeb meem tsawg thiab qis dua piv rau puv -loj multimeters. Tag nrho - cov qauv loj yog tsim los muab kev nyeem kom raug ntau dua thiab feem ntau calibrated rau cov qauv siab dua, ua rau lawv nyiam dua thaum muaj qhov tseem ceeb.
Tus neeg siv tswj thiab nta
Tag nrho-loj digital multimeters feem ntau suav nrog cov yam ntxwv siab heev xws li xaiv qhov ntsuas ntsuas, cov ntaub ntawv tuav haujlwm, min / max capture, thiab qee zaum txuas rau kev kaw.
