1. Raws li qib ntawm qhov ntsuas voltage
High-voltage xeem cwj mem: siv rau 10kv thiab saum toj no tej yaam num, thiab nws yog ib tug niaj hnub xeem cov cuab yeej rau electricians;
Tsawg-voltage xeem cwj mem: siv lub cev them ntawm cov kab hluav taws xob ntawm 500V thiab hauv qab no txhawm rau txheeb xyuas.
Kev ntsuas hluav taws xob tsis muaj zog: siv rau kev ntsuas cov khoom siv hluav taws xob, qhov ntsuas qhov ntsuas dav dav yog 6v--24v. Rau kev yooj yim ntawm kev siv, tus Tsov tus tw ntawm tus cwj mem hluav taws xob feem ntau muaj cov hlau lead nrog cov clip.
2. Raws li txoj kev tiv tauj
Tiv tauj xeem cwj mem: ib qho cuab yeej nrhiav kom tau txais hluav taws xob teeb liab los ntawm kev tiv tauj lub cev them nyiaj. Feem ntau muaj hom ntsia hlau tiaj tiaj, uas kuj yog siv rau kev ntsuas hluav taws xob cwj mem thiab lub hau ntswj tiaj tus; cwj mem, uas qhia cov ntaub ntawv ntsuas ncaj qha rau ntawm lub qhov rais LCD.
Inductive Test Pen: Inductive xeem yam tsis muaj kev sib cuag ntawm lub cev los xyuas qhov voltage ntawm kev tswj cov xov hlau, cov khoom siv hluav taws xob thiab cov qhov (sockets) lossis tshawb xyuas qhov chaw qhib qhov chaw nyob ntawm cov xov hlau. Kev nyab xeeb ntawm tus kheej ntawm cov neeg soj ntsuam tuaj yeem lav tau qhov loj tshaj plaws.
3. Neon tube xeem cwj mem
Neon tube type test cwj mem, tseem hu ua hluav taws xob cwj mem, yog siv los ntsuas seb cov hlau casing ntawm cov xov hlau, cov khoom siv hluav taws xob thiab cov khoom siv hluav taws xob raug them. Hom cwj mem hluav taws xob no tau muab faib ua ob hom: cwj mem thiab hom ntsia hlau.
4. Digital zaub cwj mem
Cov ntawv ntsuas ntsuas tus cwj mem kuj tseem hu ua inductive test cwj mem. Cov cwj mem hluav taws xob zoo li no tuaj yeem tsis tsuas yog kuaj seb cov khoom puas raug them, tab sis kuj tso saib qhov kwv yees qhov hluav taws xob ntau. Qee cov cwj mem ntsuas digital tuaj yeem ntes cov hlau tawg ntawm cov hlau tsis muaj hluav taws xob.
