Yuav ua li cas txheeb xyuas luv luv thiab tawg circuits nrog ib tug multimeter
Multimeter rau kev koom nrog hauv cov khoom siv hluav taws xob, hluav taws xob hais txog, kev saib xyuas cov phooj ywg, yog qhov tsim nyog "cov tub ntxhais kawm nyuaj" cov cuab yeej, muaj zog heev, tuaj yeem siv los ntsuas AC voltage, DC voltage, AC tam sim no, DC tam sim no, tsis kam, capacitance, diode, transistor, kub thiab lwm yam. Piv txwv li, thaum peb tab tom sim thiab debugging cov khoom, peb yuav tsum siv lub multimeter los pab nrhiav teeb meem.
Thaum cov khoom lag luam ua tsis tiav, kuv feem ntau pib los ntawm kev ntsuas cov tswv yim thiab cov zis voltages nrog cov khoom siv hluav taws xob los txiav txim seb lub hwj chim ntawm qhov hluav taws xob yog qhov qub. Voltage tsis zoo li qub, ntau zaus muaj qhov luv luv lossis luv luv Circuit Court.
Buzzer iav los ntsuas luv-circuit, disconnection
Digital multimeter feem ntau muaj cov ntaub ntawv buzzer, ntsuas kev sib txuas yuav yog "BI", "BI" nplhaib, intuitive heev, tsis tas yuav ntsia lub multimeter kom pom.
Thaum ntsuas ob yuav tsum tsis txhob txuas nrog rau txoj hauj lwm, yog muab "BI", "BI" nplhaib, qhia txog ib tug luv luv Circuit Court; thaum ntsuas ob yuav tsum tau txuas nrog rau txoj hauj lwm, tab sis tsis tau muab "BI BI", "BI" nplhaib, qhia txog ib tug tawg Circuit Court;
Yog tias koj lub multimeter tsis muaj cov ntaub ntawv buzzer, koj tuaj yeem siv cov ntaub ntawv tiv thaiv, raws li txoj kev ntsuas tus nqi tiv thaiv los txiav txim seb qhov luv luv lossis kev sib txuas, yog tias qhov tsis kam ua me me, tsuas yog ob peb ohms, los yog txawm xoom ob peb ohms, uas txhais tau hais tias luv luv-circuit; Yog hais tias qhov ntsuas ntawm tus nqi kuj tsis yog los yog tus nqi kuj yog heev loj, ces nws txhais tau hais tias lub disconnection.
Nco ntsoov disconnect lub hwj chim mov thaum ntsuas nrog buzzer los yog tsis kam!
Kev ntsuas qhov dej
Cov dej xau tau muab faib ua kom muaj zog to thiab tsis muaj zog to. Lub zog hluav taws xob xau yog hais txog AC high voltage to, qhov dej xau no yuav ua rau cov neeg siv hluav taws xob los yog ua rau cov hluav taws xob hloov pauv, koj tuaj yeem ua si lub multimeter rau AC cov ntaub ntawv, ntsuas seb puas muaj qee qhov AC voltage. Lwm txoj hauv kev yog tshem tawm cov khoom siv hluav taws xob, nrog rau qhov siab tshaj plaws ntawm cov ntaub ntawv tiv thaiv, ntsuas qhov to thiab qhov hluav taws xob (L) lossis xoom kab (N) nruab nrab ntawm tus nqi tiv thaiv, yog tias tsis muaj qhov to, tus nqi tiv thaiv yog qhov zoo, sib npaug. rau rwb thaiv tsev, yog hais tias tus nqi kuj nyob rau hauv av tsis loj txaus los ntsuas tus nqi kuj ntawm ob peb puas K, ces tej zaum yuav muaj to.
Yog tias koj xav ntsuas qhov hluav taws xob tsis muaj zog ntawm qhov tsis muaj zog, koj tuaj yeem siv cov ntaub ntawv tam sim no ntawm multimeter, multimeter series series txuas rau Circuit Court los ntsuas qhov ua haujlwm tam sim no nce. Piv txwv li, cov khoom yog ib txwm standby tam sim no yog kaum ntawm microamps, tab sis ntsuas ntau pua microamps, los yog txawm mus rau ob peb milliamps mus, hais tias lub Circuit Court muaj ib tug to ntawm cov khoom. Ntsuas qhov tam sim no yog tias koj tsis paub meej txog qhov loj ntawm qhov ua haujlwm tam sim no, koj tuaj yeem pib nrog ntau yam iav loj, thiab tom qab ntawd maj mam txo qhov ntau yam los kuaj, ntau tshaj qhov yooj yim rau hlawv lub fuse ntawm multimeter.
