Kho multimeters nrog xoob leads thiab pins
1, multimeter liab thiab dub cwj mem nyob rau hauv ceg txheem ntseeg, koj muaj peev xwm rub tawm, pom ib tug hlau txiv neej lub qhov (socket) txuas nrog ib tug tawv hlau, vim hais tias cov hlws ris ntawm kab kab no yooj yim tawg, qhia rau koj, kuv tus cwj mem kab tau ntev npaum li cas. , kho ntau zaus, txhua zaus nkim 1cm, kuv muaj ob hom rooj (electronic, pointer) yog unloading kab los kho lub pointer table kab connector yog zoo los kho ib co, tsuav yog muaj ib tug threaded liab yas ntawm lub txheej ntawm unscrewing cov hlau ceg txheem ntseeg clamped mus rau ib tug vise, siv ib tug soldering hlau rau yaj nyob rau hauv lub solder hlau, thiab ces cov tawv hlau stripped tawm ib nrab ib centimeter los qhia cov tooj liab hlau, melted nrog tin. Nyob rau hauv ib lub vise, nrog ib tug soldering hlau melted nyob rau hauv lub solder hlau, thiab ces stripped tawm ib nrab ib tug centimeter ntawm tawv hlau, exposing tooj liab hlau, melted nrog tin, nws yog ib qhov zoo tshaj plaws mus teem ib lub insulating wax raj rau ntawm kab, yog li ntawd. tom qab soldering sab nraum lub casing yuav tsis yooj yim rau tawg.
2, rau lub rooj digital ntawm ceg txheem ntseeg tsis zoo heev vuam, nws yog cov yas npog thiab loj thiab tawv, koj yuav tsum rub tawm thawj kab los ntawm txoj kab, welded rau sab nraud thiab rov qab mus rau nws txoj haujlwm qub, yog tias koj txawm vuam tshuab tsis yog, nws yog ib qho nyuaj rau tau!
Saib cov cwj mem liab liab saum toj no yog lub tes tsho yas uas tau kho thiab tom qab ntawd ironed khov kho nrog cov hlau nplaum kom ruaj ntseg tawg.
Cov neeg uas muaj peev xwm ua tau thiab siv lub tshuab multimeter yuav muaj qee qhov kev paub thiab cuam tshuam rau cov khoom siv hauv xov tooj cua thiab hluav taws xob rau kev kho, thiab yuav tsis muaj peev xwm siv cov hlau soldering, uas tuaj yeem sib cais thiab soldered.
Multimeter los ntsuas qhov luv luv Circuit Court
Ua ntej tshaj plaws, tus cwj mem dub ntawm multimeter rau hauv "com" qhov, tus cwj mem liab rau hauv "V Ω" qhov, lub pob qhov rooj mus rau qhov chaw beeping. Cov kab yuav raug kuaj los ntawm kev txiav lub hwj chim, ob lub cwj mem tau ntsuas kab ntawm ob kab, yog tias cov khoom siv multimeter kuj yog {{0}}, thiab muaj lub suab beeping, qhia tias kab muaj ib tug short-circuit phenomenon. Kuj tseem muaj cov ntaub ntawv ohm 1k lossis 10k cov ntaub ntawv, tshem tawm lwm qhov kawg ntawm txoj kab, ob lub cwj mem los ntsuas ob kab, yog tias qhov ntsuas ntau yam tsis kam qhia 0, qhia qhov luv luv hauv kab.
Multimeter xeem tawg
Thaum peb ntsuas qhov on-off ntawm kab, peb yuav tsum tau txiav lub hwj chim mov ua ntej kuaj. Tig lub pob qhov rooj mus rau lub iav beeping, txhawm rau kuaj ob qhov kawg ntawm txoj kab raug kov rau cov hlau tus pin ntawm lub ntsuas mem, yog tias muaj qee yam tsis kam, thiab muaj lub suab beeping, nws txhais tau hais tias kab yog nyob rau; Yog hais tias qhov kev tiv thaiv yog infinite, cov zaub yog 1, thiab tsis muaj beeping suab, ces cov kab yog disconnected. Los yog multimeter xaiv 10k iav, lwm qhov kawg ntawm txoj kab kom luv, nrog rau tus cwj mem multimeter los ntsuas ob lub xov hlau, yog tias qhov multimeter tsis kam qhia 1, nws txhais tau tias nws raug txiav; qhia 0, tej zaum yuav yog kab nyob rau.
