Nnwale mgbochi nke akwụkwọ{0}} mkpuchi mkpuchi na rọba {{1}plastic{2}}Ụdị eriri mkpuchi na-agụnye naanị mkpuchi mkpuchi yana iguzogide ule voltaji.
Mgbe ị na-anwale nguzogide mkpuchi ikuku, biko mara ihe ndị a:
1) Usoro nha nguzogide mkpuchi dị mma maka eriri nke ogologo ogologo. A na-ejikarị megohmmeter tụọ na gbakọọ oke nnabata. N'okpuru otu ọnọdụ ule ahụ, ka mma mkpuchi eriri USB, nke dị elu nke absorption ruru.
2) Ọ dịghị n'ozuzu ọ dịghị kpọmkwem ụkpụrụ maka USB mkpuchi ụkpụrụ. Ekwesịrị ikpebi ọnọdụ mkpuchi nke eriri site na iji ya tụnyere ihe ndekọ mbụ. N'ihi na okpomọkụ na-emetụta nguzogide mkpuchi nke eriri, ọnọdụ ihu igwe dị ka okpomọkụ ikuku na iru mmiri kwesịrị idekọ n'oge ule mkpuchi eriri maka ebumnuche ntụnyere.
3) Megohmmeter iji: Maka eriri na voltaji n'okpuru 1 kV, jiri 500-1000 V megohmmeter; maka eriri nwere voltaji nke 1 kV na n'elu, jiri megohmmeter 1000-2500 V.
4) Tupu anwale, eriri ahụ ga-agbapụta n'ụzọ zuru ezu ma gbanye ya site n'itinye isi ihe na-eduzi na n'ọbọ ígwè nke eriri.
5) Tupu nnwale, hichaa elu nke eriri ọdụ USB ka ibelata ntapu elu. Jiri isi eriri USB mkpuchi mkpuchi ọzọ dị ka loop mkpuchi. Jikọọ ndị na-eduzi na nsọtụ abụọ nke isi mkpuchi a na aka aka ma ọ bụ mkpuchi nke isi mkpuchi a na-anwale waya ígwè na-agbanwe agbanwe, na-ekechi ha ọtụtụ ugboro tupu ijikọta ha na njedebe ọta nke megohmmeter.
6) Mgbe ọ bụla ihe mkpuchi mkpuchi mkpuchi, wepụ ma gbanye eriri ahụ. Ogologo ogologo eriri USB, ka ọnọdụ mkpuchi ahụ ka mma. Oge ntọ ala kwesịrị ịdị ogologo, n'ozuzu opekata mpe otu nkeji.
Nnwale voltaji na-eguzogide DC bụ ule kachasị mkpa maka inyefe ọrụ USB ma ọ bụ nnwale mgbochi, ọ bụkwa ihe ndabere kachasị maka ịchọpụta ma eriri eriri ọ dabara maka ịrụ ọrụ. Igwe na-arụ ọrụ kwesịrị ịdị na-anwale ule voltaji na-anagide DC mgbe niile, yana a ga-atụkwa anya mmiri na-agbapụta ugbu a.
