Yuav ua li cas ntsuas voltage
Ib tus cwj mem xeem siv los txiav txim seb lub xov tooj puas nyob yog hom khoom siv hluav taws xob thiab hluav taws xob hu ua "digital display test pen." Lub cev ntawm digital zaub cwj mem nta ib qho LED zaub uas ua rau nws yooj yim los saib cov lej ntsuas hluav taws xob. Kev ua haujlwm ntawm tib neeg lub cev feem ntau tsis tshua muaj, tsuas yog ob peb puas mus rau ntau txhiab ohms, thiab qhov kev tawm tsam ntawm tus cwj mem xeem feem ntau yog hais txog ntau megohms thaum ntsuas cov hlau nyob, lub teeb pom kev zoo, qhov voltage U=220 V nruab nrab ntawm cov hlau nyob thiab hauv av. Tam sim no (piv txwv li, tam sim no ntws los ntawm tib neeg lub cev) yog qhov tsawg heev; Nws feem ntau poob qis dua 1 mA.Cov neeg tsis raug mob thaum xws li ib qho me me tam sim no ntws los ntawm lawv lub cev, thiab lub teeb yog tsim thaum xws li ib tug me me tam sim no ntws los ntawm lub xeem cwj mem lub neon noob.
Cov lus qhia siv khawm muaj txiaj ntsig:
(Ib tus yuam sij) Thov thawb lub pob no thaum siv lub taub hau batch kom ncaj qha mus rau kab; DIRECT, tus yuam sij ntsuas ncaj qha (nyob deb ntawm lub vaj huam sib luag LCD;
(B yuam sij) Thov nias INNDUCTANCE, lub khawm ntsuas induction (ze rau ntawm lub vijtsam LCD), siv lub taub hau batch los xyuas cov kab sib cuag.
Thov nco ntsoov tias tus yuam sij sensor nyob ze tshaj plaws ntawm lub vijtsam LCD thiab qhov ntsuas ntsuas ncaj qha nyob deb, tsis hais seb lub cwj mem hluav taws xob luam tawm li cas.
Cov cwj mem xeem no tuaj yeem siv los txheeb xyuas qhov hluav taws xob ncaj qha ntawm 12-250 volts AC thiab DC nrog rau kev ntsuas tsis ncaj, theem, thiab AC breakpoints. Nws tseem tuaj yeem ntsuas qhov txuas ntxiv ntawm cov xov hlau uas tsis muaj zog.
Kev lees paub ncaj qha
Tus nqi ntsuas voltage yog sawv cev los ntawm tus lej kawg; tus nqi qis qis yog pom thaum 70 feem pua ntawm cov khoom tawg siab tsis tau txais; thaum ntsuas qhov hluav taws xob ncaj qha, kov tus ncej sab nraud nrog koj xib teg;
Indirect detection:
Nias thiab tuav lub pob B thiab txav lub taub hau mus ze rau ntawm txoj hlua hluav taws xob. Yog hais tias lub hwj chim qaum raug them, cov zaub ntawm tus cwj mem digital yuav pom lub cim hluav taws xob siab
Breakpoint detection:
Nias thiab tuav tus yuam sij B thiab txav mus rau longitudinally raws cov hlau, qhov taw tes uas tsis muaj cov duab nyob rau hauv lub qhov rais zaub yog lub breakpoint.
Tus cwj mem tshiab digital zaub tuaj yeem kuaj 12V, 36V, 55V, 110V thiab 220V. Feem ntau, qhov taw tes rau saum tus cwj mem xeem yog qhov ntsuas hluav taws xob, thiab cov khoom siv siab tshaj plaws yog qhov ntsuas hluav taws xob tam sim no; hauv qab yog qhov kev ntsuam xyuas induction los xyuas cov insulators Nyob rau hauv rooj plaub ntawm Circuit Court breakage, qhov no yog raws li kev paub.
Kev ntsuas hluav taws xob:
1. Qhov ntsuas qhov ntsuas yog AC / DC voltage ntawm 12-250V.
2. Maj mam kov lub khawm DIRECT, thiab cov hlau pem hauv ntej kawg ntawm tus cwj mem ntsuas kov cov khoom yuav raug kuaj. Tus cwj mem xeem muaj tsib qhov ntsuas hluav taws xob: 12V, 36V, 55V, 110V thiab 220V. Tus nqi kawg ntawm lub vijtsam LCD yog ntsuas tus nqi hluav taws xob (Thaum nws tsis ncav cuag 70 feem pua ntawm cov khoom siv high-end, tus nqi qis kawg yog pom).
3. Thaum ntsuas tsis yog hauv av ncaj qha tam sim no, tes yuav tsum kov lwm yam electrode (xws li qhov zoo lossis qhov tsis zoo).
Induction Detection:
1. Kov lub khawm INDUCTANCE, thiab cov hlau pem hauv ntej kawg ntawm tus cwj mem xeem yog nyob ze rau ntawm cov khoom kom kuaj pom. Yog tias "high voltage symbol" tshwm rau ntawm cov zaub, nws txhais tau hais tias cov khoom raug them nrog alternating tam sim no.
2. Thaum ntsuas cov hlau tsis sib txuas, kov lub khawm INDUCTANCE, cov hlau pem hauv ntej kawg ntawm tus cwj mem xeem yog nyob ze rau ntawm insulating txheej txheej ntawm cov hlau, muaj qhov tshwm sim tsis sib xws, thiab "high voltage symbol" disappears ntawm lub breakpoint.
3. Siv txoj haujlwm no kom yooj yim paub qhov txawv ntawm xoom thiab theem kab (thaum ntsuas cov kab sib txuas, nce qhov kev ncua deb ntawm kab). Tshawb xyuas microwave tawg thiab to.
Cov kev ceev faj:
Cov yuam sij tsis tas yuav tsum raug nias nyuaj, thiab ob lub xeem yuam sij tsis tuaj yeem kov tib lub sijhawm thaum lub sijhawm xeem, txwv tsis pub qhov rhiab heev thiab kev xeem yuav raug cuam tshuam.
