Multimeters yog qhov tsim nyog rau txhua hom kev ua haujlwm hluav taws xob. Los ntawm kev txhim kho lub qab nthab kiv cua kom hloov lub thawv sib txuas, siv a multimeter pab txiav txim seb cov xov hlau kub los yog tsis (thiab ntau ntxiv). Multimeters yog tsim los ntsuas peb yam tseem ceeb ntawm hluav taws xob hluav taws xob: volts, amps thiab ohms.

Tom qab ntawd, lub hom phiaj ntawm multimeter yog dab tsi?

A multimeter los yog multitester, tseem hu ua VOM (Volt-Ohm-Milliammeter), yog ib qho khoom siv hluav taws xob ntsuas hluav taws xob uas sib txuas ntau yam ntsuas hauv ib chav. Ib yam multimeter tuaj yeem ntsuas qhov voltage, tam sim no, thiab tsis kam. Analog multimeters siv lub microammeter nrog lub pointer txav los tso saib kev nyeem ntawv.

Ib yam li ntawd, multimeter puas xav tau roj teeb? Yog koj multimeter yog digital, nws yuav xav tau me me roj teeb ua haujlwm. Yog hais tias nws yog analogues ua tsis yog xav tau a roj teeb ntsuas qhov voltage. Qee qhov digital multimeters yog autoranging. Ib qho autoranging meter tsuas muaj ob peb xaiv xaiv (dial) txoj haujlwm.

Ntawm no, dab tsi koj yuav tsum tsis txhob ua nrog ib tug multimeter?

Cov Lus Qhia Kev Nyab Xeeb rau Kev Ntsuas Voltage Nrog Multimeter

  1. Tsis txhob siv koj cov kev xeem coj mus kuaj yog tias cov rwb thaiv tsev tiv thaiv ntawm cov hlau lead lossis kev sojntsuam raug tawg lossis hnav.
  2. Kev txav ntawm tam sim no ntawm ib sab mus rau lwm qhov thaum lub sij hawm hluav taws xob poob siab yog qhov txaus ntshai tshaj plaws.
  3. Ob lub DC thiab AC voltage tuaj yeem txaus ntshai heev.

Dab tsi yog peb yam tseem ceeb tshaj plaws uas tus multimeter tuaj yeem ntsuas tau?

Kawm paub multimeters tuaj yeem ntsuas ntau yam nqi. Cov feem ntau yog: Voltage, alternating thiab ncaj qha, nyob rau hauv volts. Tam sim no, alternating thiab ncaj qha, nyob rau hauv amperes.
