Ngaba uyayiqonda nyani into yokhuseleko?

Imeko yesicelo yesixhobo sovavanyo lokhuseleko
Ukusetyenziswa kwezixhobo zokuvavanya ukhuseleko kuxhaphakile, ikakhulu kusetyenziswa kwimveliso, ulondolozo, kunye nophando olunxulumene nezixhobo ezahlukeneyo ze-elektroniki. Imeko yesicelo eqhelekileyo ibandakanya ukuhanjiswa kwamandla, ukukhanya kwe-LED, izixhobo zekhaya, izixhobo zonyango, izixhobo zonxibelelwano, izixhobo zemveliso zemveliso, amandla amatsha kunye namanye amasimi. Kwezi meko, indima yeentengo zokhuseleko zibalulekile kuba kuphela uvavanyo oluchanekileyo nolugqibeleleyo unokuqinisekisa ukuba iimveliso eziveliswayo zihlangabezane nemigangatho yokhuseleko yombane ebekwe lilizwe kunye neshishini.

Umxholo wovavanyo lwe-tester yokhuseleko
Ngokubanzi, umxholo wovavanyo lwexesha lokhuseleko lubandakanya oku kulandelayo: I-AC Comand I-Voltage, i-DC iquleza i-voltage, ukunyangwa kwe-itshi, uvavanyo lwesekelo, njl. Njl. Ke, kukho Nxibelela imixholo ethile yokuvavanya ekufuneka yenziwe yecandelo elithile. Makhe sichaze enye nganye.
1. Uvavanyo lokunyamezelana kwee-voltage: Faka i-voltage voltage enkulu yamawaka amawaka eVolts (AC okanye i-DC) phakathi kwendawo yokucoca okanye i-DC) yefowuni evavanyiweyo kunye ne-terminal yentengo evavanyiweyo ukufumana ubungakanani bokuvuza ngoku. Xa ukuvuza ngokudlula kudlula ixabiso elithile, kunokubangela ingozi emzimbeni womntu.
I-2. Ukungeniswa okwangoku: Ukwahlula-hlulwe ngokwase-Dynamic ukuvuza kunye nokuvuza kwe-static.
(1) Ukuvuza okumileyo Ngeli xesha, isixhobo sombane esivavanyiweyo asisebenzi. Ukusetyenziswa kwamaxesha oku-1.06 i-voltage kufuneka ibonelelwe ngotshintsho lwedwa.
.
. Ukufakwa kwentengo ye-tester kufuna ukufaka uthungelwano lwenethiwekhi yomzimba womntu. Imigangatho yemveliso eyahlukileyo yombane inemodeli eyahlukileyo yomzimba, ekufuneka ikhethwe ngokuchanekileyo. Imigangatho yesizwe ehambelana ne-GB9706 GB3883, GB2898, GB4943, GB49043, GB4706, GB4706, GB4706. Umthamo woCentral of Desters ngoku kufuneka ulungele indlela yokulinganisa. Xa isixhobo sombane esivavanyiweyo sisimo semoto okanye injenge-enje, kwaye ukuqala kwayo amaxesha ngamaxesha ngaphezulu kunexesha elichithwayo, kufuneka ithathelwe ingqalelo ngokusekwe ekuqaliseni okwangoku.
3. Ukubuyiswa kokunganyangeki kwe-Interser Ukunganyangeki.
I-4. Uvavanyo lokuxhathisa ubuncwane: Faka isicelo sexesha eliphakamileyo langoku (i-10a okanye i-10a okanye i-25A) phakathi kwesixhobo esivavanyiweyo sombane esivavanyiweyo kunye nesiphelo sendlela yokufumana ukunyangwa kwendlela. Ukuxhathisa kakhulu akuboneleli ngokukhusela.
