Namuhla sizokwabelana ngendlela yokwahlulela ukuthi inzwa isebenza ngokujwayelekile.
Okokuqala, sidinga ukwazi ngaphansi kwaziphi izimo okudingeka sahlulele ukusebenza kwe-inzwa. Kunamaphuzu amabili alandelayo:
1. Isisindo esivezwa inkomba yokukala asihambisani nesisindo sangempela, futhi kunomehluko omkhulu.
Uma sisebenzisa izisindo ezijwayelekile ukuhlola ukunemba kweisikali, uma sithola ukuthi isisindo esiboniswa inkomba sihluke kakhulu kwesisindo sokuhlola, futhi iphuzu elinguziro nobubanzi besikali akukwazi ukushintshwa ukulinganisa, khona-ke kufanele sicabangele ukuthi inzwa ayiphukile yini. Emsebenzini wethu wangempela, sihlangabezane nesimo esinjalo: iphakheji enesisindo sokulinganisa, isisindo sephakheji yephakheji lokuphakelayo singama-20KG (isisindo sephakheji singasethwa njengoba kudingeka), kodwa lapho isisindo sephakheji sihlolwe ngesilinganiso se-electronic , Kuphakathi noma ngaphansi, okuhluke kakhulu kumthamo ohlosiwe we-20KG.
2. Ikhodi ye-alamu "OL" ivela kunkomba.
Le khodi isho ukukhuluphala ngokweqile. Uma inkomba ivame ukubika le khodi, hlola ukuthi ingabe inzwa isebenza kahle yini
Ungahlulela kanjani ukuthi inzwa isebenza ngokujwayelekile
Ukumelana nokulinganisa (Isikhombi sokunqamula)
(1) Kungaba lula kakhulu uma kukhona imanuwali yezinzwa. Okokuqala sebenzisa i-multimeter ukukala ukumelana nokokufaka nokuphumayo kwenzwa, bese uyiqhathanisa nemanuwali. Uma kukhona umehluko omkhulu, uzophulwa.
(2) Uma ingekho imanuwali, bese ukala ukumelana nokokufaka, okuwukumelana phakathi kwe-EXC+ ne-EXC-; ukumelana nokuphumayo, okuwukumelana phakathi kwe-SIG+ ne-SIG-; ukumelana kwebhuloho, okuyi-EXC+ kuya ku-SIG+, EXC+ kuya ku-SIG-, Ukumelana phakathi kwe-EXC- kuya ku-SIG+, EXC- kuya ku-SIG-. Ukumelana nokokufaka, ukumelana nokuphumayo, nokumelana nebhuloho kufanele kwenelise ubudlelwano obulandelayo:
"1", ukumelana nokokufaka＞ukumelana nokuphumayo＞ukumelana nebhuloho
"2", ukumelana kwebhuloho kuyalingana noma kuyalingana.
I-voltage yokulinganisa (inkomba inikwe amandla)
Okokuqala, sebenzisa i-multimeter ukukala i-voltage phakathi kwe-EXC+ ne-EXC- terminals yenkomba. Lena i-voltage ye-excitation yenzwa. Kukhona i-DC5V ne-DC10V. Lapha sithatha i-DC5V njengesibonelo.
Ukuzwela okukhiphayo kwezinzwa esizithintile ngokuvamile kungu-2 mv/V, okungukuthi, isignali yokuphuma kwenzwa ihambisana nobudlelwano bomugqa obungu-2 mv kuwo wonke ama-voltage e-excitation angu-1V.
Uma kungekho mthwalo, sebenzisa i-multimeter ukukala inombolo ye-mv phakathi kwemigqa ye-SIG+ ne-SIG. Uma imayelana ne-1-2mv, kusho ukuthi ilungile; uma inombolo ye-mv inkulu kakhulu, kusho ukuthi inzwa ilimele.
Uma ulayisha, sebenzisa ifayela le-multimeter mv ukukala inombolo ye-mv phakathi kwezintambo ze-SIG+ ne-SIG-. Izokwanda ngokulingana nesisindo esilayishiwe, futhi esiphezulu yi-5V (i-voltage excitation) * 2 mv / V (ukuzwela) = mayelana ne-10mv, uma kungenjalo , Kusho ukuthi inzwa yonakalisiwe.
1. Awukwazi ukweqa ububanzi
Ububanzi obuningi obuvamile buzodala umonakalo ongenakulungiseka emzimbeni onwebekayo kanye negeji yokucindezeleka ngaphakathi kwenzwa.
2. Ukushisela ngogesi
(1) Nqamula intambo yesiginali kusilawuli sokubonisa isisindo;
(2) Intambo ephansi ye-welding kagesi kufanele isethwe eduze nendawo eshiselwe, futhi inzwa akufanele ibe yingxenye yesekethe yokushisela kagesi.
3. Ukufakwa kwentambo yezinzwa
I-insulation yekhebula lenzwa isho ukumelana phakathi kwe-EXC+, EXC-, SEN+, SEN-, SIG+, SIG- kanye ne-SHIELD yocingo oluvikelayo. Lapho ukala, sebenzisa ifayela lokumelana ne-multimeter. Igiya likhethwa ku-20M, futhi inani elilinganisiwe kufanele libe elingapheli. Uma kungenjalo, inzwa ilimele.
