Yuav ua li cas siv lub multimeter
1. Paub koj tus kheej nrog kev ua haujlwm ntawm multimeter ua ntej siv, thiab xaiv cov iav kom raug, ntau yam thiab ntsuas cov hlau lead jack raws li cov khoom yuav ntsuas.
2. Thaum qhov loj ntawm cov ntaub ntawv ntsuas tsis paub, qhov hloov pauv yuav tsum tau teeb tsa rau qhov siab tshaj plaws ua ntej, thiab tom qab ntawd hloov ntawm qhov loj mus rau qhov me me, kom tus taw tes ntawm lub 'meter' qhia ntau tshaj 1/2 ntawm qhov ntsuas tag nrho.
3. When measuring the resistance, after selecting the appropriate magnification gear, touch the two test pens to make the pointer point at the zero position. If the pointer deviates from the zero position, adjust the "zero" knob to make the pointer return to zero to ensure accurate measurement results. . If it cannot be adjusted to zero or the digital display emits a low voltage alarm, it should be checked in time.
4. Thaum ntsuas qhov kev tiv thaiv ntawm ib lub voj voog, lub hwj chim ntawm lub voj voog nyob rau hauv kev sim yuav tsum raug txiav tawm, thiab tsis pub ntsuas nyob.
5. Thaum siv multimeter los ntsuas, xyuam xim rau kev nyab xeeb ntawm tus neeg thiab cov cuab yeej thiab cov cuab yeej siv. Thaum lub sij hawm xeem, tsis txhob kov cov hlau ib feem ntawm lub xeem cwj mem nrog koj txhais tes, thiab nws tsis raug tso cai hloov lub iav hloov nrog hluav taws xob los xyuas kom meej qhov ntsuas thiab tsis txhob muaj xwm txheej xws li hluav taws xob poob siab thiab hlawv.
