1. Tsis muaj hwj chim lossis tsis teb
Tej Yam Ua Tau: Lub tshuab hluav taws xob tsis zoo, lub zog hluav taws xob tsis zoo sib txuas, cov khoom siv hluav taws xob puas, lub rooj tswj hwm lub luag haujlwm tseem ceeb, kev sib txuas hauv cov cable, thiab lwm yam.
Lus Cim Tshwj Xeeb: Yog tias lub ntsiab lus tseem ceeb ntawm pawg thawj coj saib xyuas tsis tau teeb, xyuas lub hwj chim board, auxiliary transformer, thiab reactor Cheebtsam.
2. Zaub tsis ua haujlwm (Tsis muaj zaub, npo cais, cov cim tsis zoo)
Zaub backlight yog nyob rau tab sis tsis muaj ntawv nyeem: Qhov no tej zaum yuav yog vim tsis raug brightness hloov pob qhov chaw, ib tug luv luv Circuit Court nyob rau hauv lub teeb cwj mem cable, los yog ib tug malfunction nyob rau hauv lub Suav cim converter board.
Screen Split lossis Garbled Characters: Qhov no feem ntau cuam tshuam nrog kev tiv thaiv tsis zoo; sim ntxiv daim ntawv tiv thaiv los yog hloov lub ntsiab tswj lub rooj tsavxwm.
Cov nyees khawm teb tab sis tsis muaj zaub: Xyuas cov zaub cable, hloov dua siab tshiab cable, thiab lub ntsiab tswj kev sib txuas.
3. Kev ua haujlwm tsis zoo (Qhib Circuit Court, luv Circuit Court, tsis kam tshaj qhov txwv)
Kev nthuav qhia "Output Open Circuit" lossis "Resistance Exceeds Lower Limit": Qhov no feem ntau tshwm sim los ntawm qhov txawv txav PE yeeb nkab fittings lossis kev sib txuas tsis zoo; xyuas thiab hloov cov fittings.
"Short Circuit" Tswb: Qhov no tej zaum yuav yog vim lub luv luv Circuit Court nyob rau hauv lub cua sov caij nyob rau hauv lub electrofusion haum, los yog cov tooj liab xov hlau ua tangled thaum vuam, ua rau ib tug txo nyob rau hauv tsis kam.
Cov zis qhib Circuit Court: Siv lub tshuab ntsuas ntau los kuaj xyuas qhov sib tsoo, kom ntseeg tau tias muaj hluav taws xob zoo nrog kev tiv thaiv tsis tshaj 0.01Ω.
4. Cov txheej txheem vuam tsis zoo
Vuam nres ua ntej ua tiav: Feem ntau tshwm sim los ntawm qhov tsis ruaj khov input voltage, ntev ntev cables, lossis lub tshuab hluav taws xob tsis txaus.
Tam sim no tsis nce: Qhov no tej zaum yuav yog vim tsis txaus sab nraud fais fab mov voltage los yog ntev lub hwj chim kab ua rau overvoltage poob.
Overcurrent/Overvoltage Alarms: Tshawb xyuas cov teeb meem hluav taws xob sab nraud thiab xa rov qab.
Cov pa luam yeeb, cov khoom siv tshuaj tsuag, lossis hluav taws kub thaum lub sij hawm vuam: Qhov no tej zaum yuav tshwm sim los ntawm kev sib txuas tsis zoo, tooj liab xaim misalignment, lossis tsis ruaj khov vuam tshuab tso zis hluav taws xob.
5. Scanner nyeem tsis tau
Ua rau muaj xws li xoob kho qhov muag cwj mem kev sib txuas lus cable, cov khoom lim puas, kev sib cuag tsis zoo ntawm lub qhov muag cwj mem txuas, lossis kev ua haujlwm tsis zoo hauv tus cwj mem optical nws tus kheej.
6. Kev kub siab tshaj Terminals lossis Cables
Kev laus lossis kev sib cuag tsis zoo ntawm cov zis hlau tooj liab cap yog qhov ua rau lub ntsiab; kho lossis hloov cov khoom yuav tsum tau ua kom sai.
7. Qhov txawv txav tsis zoo ntawm vuam Parameter
Tsis tuaj yeem ua haujlwm raws li kev teeb tsa: Qhov no yuav yog vim qhov ntsuas tam sim no uas qis dhau. Nws raug nquahu kom kho qhov tsis muaj thiab sim dua.
