Cov lus teb los ntawm peb cov neeg siv khoom txog peb GVDA GD113A Siab Tsis Siv Neeg Hluav Taws Xob Hluav Taws Xob Hluav Taws Xob Hluav Taws Xob Digital Multimeter, Nws pib hnov qhov xoom thiab hluav taws xob nrawm nrawm ntsuas qhov ntsuas hluav taws xob, tam sim no, tus neeg xyuas pib qhib / tawm, Xim Ring Resistance
Qhov no yog qhov zoo tshaj plaws hauv hnab tshos multimeter uas ua ntau yam uas koj yuav ua nrog lub multimeter yam tsis muaj ntau thiab hloov ntawm hom. Hauv kuv qhov kev paub, hom pib ua haujlwm zoo hauv kev ntsuas DC / AC voltages. Rau AC voltages, nws kuj qhia koj qhov zaus nyob rau tib lub sijhawm yam tsis muaj toggling deb ntawm qhov screen. Tib lub sijhawm thaum lub hom pib zoo li me ntsis funky yog tias koj ntsuas qhov voltage hauv millivolt ntau yam thiab nws tsis paub tias koj tab tom sim ntsuas qhov voltage lossis tsis kam. Nws kuj tseem tuaj yeem hloov mus rau sab nraud yog tias lub zog tsis nrov thiab ob qho tib si DC thiab AC voltage caij ntawm tib lub channel.
NCV muaj nuj nqi tiag tiag yog qhov nthuav vim tias muaj ob hom NCV sib txawv - hom Live tiag tiag siv cov tshuaj ntsuam xyuas xim hlau uas koj ntxig rau cov liab lossis dub tshuaj ntsuam hauv lub qhov (socket) thiab nws yuav qhia koj seb lub qhov (socket) / cov khoom puas muaj zog, thiab v-Alert hom uas qhia rau koj tib yam tab sis siv lub hau yas rau saum lub multimeter.
Txawm hais tias cov duab qhia hauv daim ntawv teev npe uas piav qhia nws siv rau kev kuaj xyuas US-raws li lub qhov (socket), lub taub hau pem hauv ntej yog qhov tseeb tsis tob txaus los ceeb toom rau thiab feem ntau koj yuav tsis tau txais ib qho beeps tshwj tsis yog tias koj qhib hom rhiab heev (uas cranks txoj kev rhiab heev heev rau lub hom phiaj no). Vim li no, v-Alert hom ua haujlwm zoo dua rau cov cables uas twb tau txuas rau hauv lossis rau kev taug qab ib tus neeg nyob hauv lub thawv ntim khoom. Rau kev kuaj xyuas qhov twg yog qhov nyob, siv LIVE hom nrog ib tus prong ua haujlwm zoo dua vim tias cov txhuas nkag mus tob rau hauv lub qhov (socket) dua li cov lus qhia saum toj.
Hmoov tsis zoo, cov qauv no tsis tshwm sim los txhawb lub peev xwm lossis kev ntsuas tam sim no (tab sis muaj txiaj ntsig zoo uas koj yuav tsis txhob cuam tshuam lub fuse los ntawm kev siv qhov chaw nres nkoj tsis raug). Tab sis rau feem ntau cov neeg siv, qhov multimeter no ua haujlwm zoo thiab ua haujlwm zoo dua li cov khw muag khoom yuav ntau ntawm cov nqi no.
