1. Raws li kev hloov pauv ntau yam
(1) Phau ntawv ntau
Tus nqi ntawm cov cuab yeej no yog qhov tsawg, tab sis kev ua haujlwm yog qhov nyuaj dua, thiab nws yooj yim rau overload lub cuab yeej vim qhov kev xaiv tsis tsim nyog ntawm ntau yam.
(2) Tsis siv neeg ntau yam
Qhov kev pab cuam ntau yam tsis siv neeg digital multimeter tuaj yeem ua kom yooj yim rau kev ua haujlwm, tuaj yeem ua kom tsis txhob muaj ntau dhau, thiab ua kom cov cuab yeej nyob rau hauv qhov zoo tshaj plaws, yog li txhim kho qhov ntsuas qhov tseeb thiab kev daws teeb meem. Hais txog kev hais lus, tus nqi ntawm cov twj paj nruag zoo li no kuj siab heev.
2. Raws li lub hom phiaj thiab kev ua haujlwm
(1) Tsawg-qib digital multimeter Nws yog peb-thiab-ib-ib nrab nrov ntsuas nrog cov haujlwm yooj yim thiab tus nqi piv rau qhov pointer multimeter.
(2) Nruab nrab-ntau digital multimeter
①Multi-function digital multimeter: Cov ntsuas no feem ntau yog nruab nrog lub ntsuas hluav taws xob, ntsuas qhov ntsuas kub, zaus ning thaiv, thiab qee qhov kuj ntxiv rau lub Hoobkas siab tiv thaiv thaiv, conductance thaiv thiab inductance thaiv.
② Plaub-thiab-ib-ib-nrab-tus lej multimeter: Nws muaj qhov raug siab thiab ua tiav cov haujlwm, thiab tsim nyog rau kev ntsuas ntsuas.
③Voice digital multimeter: Nws muaj cov kab lus sib txuas lus, uas tuaj yeem tshaj tawm cov txiaj ntsig ntsuas los ntawm lub suab thaum pom cov lej.
(3) Kev txawj ntse digital multimeter
①Mid-range ntse digital multimeter: Hom ntsuas no feem ntau siv 4-ntsis rau 8-ntsis ib-chip microcomputer nrog RS-232 interface.
②High-end ntse ntse digital multimeter: muaj 8-ntsis rau 16-ntsis ib-chip microcomputer, nrog rau cov ntaub ntawv ua, tsis siv neeg calibration, txhaum nws tus kheej-xyuas thiab lwm yam dej num.
(4) Dual zaub thiab multi-display digital multimeter
Tus yam ntxwv ntawm cov cuab yeej dual-display yog qhov analog bar graph zaub tau ntxiv los ntawm lub hauv paus ntawm cov duab digital, uas tuaj yeem cuam tshuam sai sai rau cov txheej txheem kev hloov pauv thiab kev hloov pauv ntawm kev ntsuas. Multi-display instrument yog tsim los ntawm lub hauv paus ntawm cov khoom siv dual-display. Muaj peev xwm tso saib ntau tshaj ob pawg ntawm cov ntaub ntawv tib lub sijhawm (xws li tus nqi siab tshaj plaws, tus nqi tsawg kawg nkaus).
(5) Cov cuab yeej tshwj xeeb digital
Piv txwv li ODM5514, desktop multimeter
(6) Digital calibrator
Qhov ntsuas no muaj qhov tseeb thiab kev daws teeb meem, thiab tuaj yeem ntsuas qhov ntsuas kub, qhov hluav taws xob thiab qhov hloov pauv tam sim no
