Qhov tsis zoo voltage txhais li cas ntawm multimeter?

Multimeter ntsuas voltage, tam sim no thiab tsis kam. Raws li txoj cai, kev nyeem ntawv multimeter yog qhov zoo lossis tsis zoo, thiab koj yuav tsum muaj kev nkag siab zoo ntawm cov khoom siv hluav taws xob txhawm rau ntsuas kev nyeem ntawv. Kev nyeem tsis zoo thiab zoo multimeter, lawv txhais li cas?

Kev nyeem ntawv tsis zoo ntawm lub multimeter txhais tau hais tias tam sim no muaj ntau tshaj ntawm electrons. Hauv qhov xwm txheej zoo li no, cov khoom tau txais qhov tsis zoo.

Dab tsi koj yuav tsum tau kuaj xyuas qhov voltage ntawm multimeter?

Nov yog txhua yam koj xav tau los xyuas qhov voltage ntawm koj lub multimeter:

• Ua kom tiav multimeter
• Qhov chaw ntawm lub zog tsis cuam tshuam
• Kev paub zoo ntawm electronics thiab sciences kom nkag siab txog kev nyeem ntawv

Yuav ua li cas ntsuas voltage nrog multimeter?

Voltage yog ib qho ntawm cov teb uas tuaj yeem ntsuas nrog lub multimeter. Tam sim no, ob qho tib si analog thiab digital multimeters tuaj yeem pom hauv khw. Hauv phau ntawv qhia no, peb yuav saib ntau txoj hauv kev los ntsuas qhov voltage nrog multimeter, uas yog qhov tseem ceeb thiab siv tau rau ob qho tib si analog thiab digital multimeters.

Kauj ruam 1 - Koj puas ntsuas qhov voltage? Yog tias muaj, puas yog qhov voltage DC lossis AC? Yog tias koj ntsuas qhov hluav taws xob hauv koj lub tsev, feem ntau yuav yog AC, tab sis yog tias nws yog lub tsheb lossis lub roj teeb uas siv hluav taws xob, ces nws yuav yog DC.

Kauj ruam 2 - Tig lub selector hloov mus rau qhov tseeb voltage koj xav ntsuas. AC voltage yog cim los ntawm sine yoj. Rau DC, nws yog ib txoj kab ncaj nraim nrog ib kab dotted hauv qab nws.

Kauj ruam 3 - Nrhiav COM tso zis ntawm koj lub multimeter thiab txuas cov hlau lead dub.

Kauj ruam 4 - Nrhiav lub connector cim V thiab ntsaws rau hauv cov hlau lead liab.

Kauj ruam 5 - Rau qhov tseeb hom voltage, teem lub selector hloov mus rau qhov siab tshaj plaws tus nqi.

Kauj ruam 6 - Qhib lub cuab yeej, tsheb, lossis khoom siv hluav taws xob uas nws qhov hluav taws xob koj tab tom yuav ntsuas.

Kauj ruam 7 - Xyuas kom tseeb tias qhov kev sojntsuam dub thiab kev sojntsuam liab yog kov ob qhov kawg ntawm lub terminals ntawm lub caij koj ntsuas qhov voltage rau.

Kauj ruam 8 - Koj qhov kev nyeem ntawv voltage tam sim no yuav tshwm sim ntawm lub vijtsam multimeter.

Yuav ua li cas nyeem thiab nkag siab voltage nyeem ntawv?

Tsuas muaj ob hom kev nyeem ntawv voltage uas yuav tsum tau muab tso rau hauv lub multimeter: nyeem ntawv zoo thiab tsis zoo nyeem.

Ua ntej dhia mus rau hauv kev nyeem ntawv, nco ntsoov tias hauv ib qho multimeter, liab qhia qhov zoo thiab dub qhia tsis zoo. Qhov no kuj siv tau rau cov sensors thiab lwm cov cim thiab cov xov hlau.

Tus nqi tsis zoo txhais tau hais tias lub voj voog siv tsis yog nyob rau hauv lub xeev passive. Nws muaj qee qhov nro. Tus nqi hluav taws xob tsis zoo yog vim muaj qhov sib npaug ntawm cov khoom siv hluav taws xob. Kev nyeem ntawv zoo yog qhov txawv ntawm qhov no. Lub multimeter yuav qhia tus nqi zoo yog tias koj txuas cov xaim zoo ntawm lub peev xwm siab dua thiab cov xaim tsis zoo ntawm qhov qis dua. (1)

• CAT multimeter ntsuas
• Multimeter tas li voltage cim
