Namuhla sizokwabelana ngendlela yokwahlulela ukuthi inzwa isebenza kahle yini.
Okokuqala, sidinga ukwazi ukuthi ngaphansi kwaziphi izimo sidinga ukwahlulela ukusebenza kweinzwaKunamaphuzu amabili kanje:
1. Isisindo esiboniswa yinkomba yokulinganisa asifani nesisindo sangempela, futhi kunomehluko omkhulu.
Uma sisebenzisa izisindo ezijwayelekile ukuhlola ukunemba kwe-isikali, uma sithola ukuthi isisindo esiboniswa yisikhombisi sihluke kakhulu esisindweni sesisindo sokuhlola, futhi iphuzu elingu-zero kanye nobubanzi besikali akukwazi ukushintshwa ngokulinganisa, khona-ke kumelwe sicabangele ukuthi inzwa ayiphukile yini. Emsebenzini wethu wangempela, sihlangabezane nesimo esinjalo: isikali esilinganisa iphakheji, isisindo sephakheji sephakheji lokuphakelayo singasethwa njengoba kudingeka), kodwa lapho isisindo sephakheji sihlolwa ngesikali se-elekthronikhi , Kungaba ngaphezulu noma ngaphansi, okuhlukile kakhulu kumthamo oqondiwe ongu-20KG.
2. Ikhodi ye-alamu ethi "OL" ivela enkombeni.
Le khodi isho ukukhuluphala ngokweqile. Uma inkomba ivame ukubika le khodi, hlola ukuthi inzwa isebenza kahle yini
Indlela yokwahlulela ukuthi inzwa isebenza kahle yini
Ukumelana kokulinganisa (Isikhombisi sokunqamula)
(1) Kungaba lula kakhulu uma kukhona incwadi yemiyalelo yenzwa. Okokuqala sebenzisa i-multimeter ukukala ukumelana kokufaka nokukhipha kwenzwa, bese uyiqhathanisa nencwadi yemiyalelo. Uma kunomehluko omkhulu, izophuka.
(2) Uma kungekho manual, khona-ke linganisa ukumelana kokufaka, okungukumelana phakathi kwe-EXC+ ne-EXC-; ukumelana kokukhipha, okungukumelana phakathi kwe-SIG+ ne-SIG-; ukumelana kwebhuloho, okungu-EXC+ kuya ku-SIG+, EXC+ kuya ku-SIG-, Ukumelana phakathi kwe-EXC- kuya ku-SIG+, EXC- kuya ku-SIG-. Ukumelana kokufaka, ukumelana kokukhipha, kanye nokumelana kwebhuloho kufanele kwanelise ubudlelwano obulandelayo:
"1", ukumelana kokufaka ＞ukumelana kokukhipha ＞ukumelana kwebhuloho
"2", ukumelana kwebhuloho kuyalingana noma kuyalingana.
Ukulinganisa i-voltage (inkomba inamandla)
Okokuqala, sebenzisa i-multimeter ukukala i-voltage phakathi kwama-terminal e-EXC+ kanye ne-EXC- enkomba. Lena i-voltage yokuvuselela yenzwa. Kukhona i-DC5V kanye ne-DC10V. Lapha sithatha i-DC5V njengesibonelo.
Ukuzwela kokukhipha kwezinzwa esizithinte ngokuvamile kungu-2 mv/V, okungukuthi, isignali yokukhipha yenzwa ihambelana nobudlelwano obuqondile obungu-2 mv kuyo yonke i-voltage yokuvuselela engu-1V.
Uma kungekho mthwalo, sebenzisa i-multimeter ukukala inombolo ye-mv phakathi kwemigqa ye-SIG+ ne-SIG. Uma icishe ibe ngu-1-2mv, kusho ukuthi ilungile; uma inombolo ye-mv inkulu kakhulu, kusho ukuthi inzwa yonakele.
Uma ulayisha, sebenzisa ifayela le-mv le-multimeter ukukala inombolo ye-mv phakathi kwezintambo ze-SIG+ kanye ne-SIG. Izokhula ngokulingana nesisindo esilayishiwe, futhi okuphezulu kungu-5V (i-voltage yokuvuselela) * 2 mv/V (ukuzwela) = cishe u-10mv, uma kungenjalo, Kusho ukuthi inzwa yonakele.
1. Ayikwazi ukudlula ububanzi
Ukweqisa njalo kuzodala umonakalo ongenakulungiseka emzimbeni onwebekayo kanye negeyiji yokucindezeleka ngaphakathi kwenzwa.
2. Ukushisela ngogesi
(1) Nqamula ikhebula lesignali kusilawuli sesibonisi sokukala;
(2) Ucingo olusemhlabathini lokushisela ngogesi kumele lubekwe eduze kwengxenye eshiselwe, futhi inzwa akumele ibe yingxenye yesekethe yokushisela ngogesi.
3. Ukufakwa kwentambo yesensa
Ukufakwa kwe-insulation kwekhebula lenzwa kubhekisela ekumelaneni phakathi kwe-EXC+, EXC-, SEN+, SEN-, SIG+, SIG- kanye ne-SHIELD yentambo yomhlabathi evikelayo. Uma ulinganisa, sebenzisa ifayela lokumelana ne-multimeter. Igiya likhethwa ku-20M, futhi inani elilinganisiwe kufanele lingabi namkhawulo. Uma kungenjalo, inzwa yonakele.
