Yuav ua li cas los daws qhov kev sib txuas lus yuam kev ntawm zaus hloov pauv cua txias E6 nrog multimeter
Kev sib txuas lus yuam kev yog dab tsi? Lub hwj chim nyob rau hauv 15S, chav tsev sab hauv tsis tuaj yeem tau txais cov ntaub ntawv xa los ntawm chav tsev sab nraud; los yog thaum lub sijhawm ua haujlwm, chav tsev sab hauv tsis tau txais cov ntaub ntawv raug xa los ntawm chav tsev sab nraum zoov rau 3 feeb sib law liag, tom qab ntawd qhov kev sib txuas lus txhaum E6 yog generated.Lub tuam txhab inverter cua txias adopts kev sib txuas lus Circuit Court nyob rau hauv daim ntawv ntawm ib tug tam sim no voj, uas muaj peev xwm ua kom yooj yim thiab ua qauv raws li daim duab hauv qab no kom nkag siab tias, los ntawm kev ua U1 nquag qhib, qhov hloov ntawm U4 tuaj yeem ua ke nrog U3, thiab los ntawm kev ua U3 ib txwm qhib, qhov hloov ntawm U1 tuaj yeem synchronized nrog U1. U2 synchronization. Tswj lub sijhawm hloov pauv ntawm txhua qhov optocoupler, cov kev sib txuas lus digital tuaj yeem ua tiav hauv tsev thiab sab nraum zoov.
Yuav ua li cas mus kuaj nrog ib tug multimeter? Qhia ob peb yam kev paub:
Kauj Ruam 1: Tom qab ua kom lub zog thiab tig lub zog, siv cov ntaub ntawv multimeter AC los kuaj seb lub tsev sab nraud puas siv tau, thiab seb qhov LN voltage puas zoo li qub? --------- Yog tias nws tsis muaj zog, tshawb xyuas lub tshuab txuas sab hauv lossis sab nraud txuas;
Kauj Ruam 2: Voltage ib txwm rau kev sim hauv qab no
Kauj ruam 3: multimeter DC cov ntaub ntawv xeem N-COM voltage, qhov voltage yog 0, kev sib txuas lus fais fab mov Circuit Court yog tsis zoo los yog lub sab nraud maub los lub hwj chim terminals tsis plugged nyob rau hauv, kos lub sab nraud hluav taws xob lub thawv ntawm lub hwj chim mov terminal kev twb kev txuas, paub meej tias qhov hloov pauv;
Kauj ruam 4: multimeter DC cov ntaub ntawv xeem N-COM voltage, qhov voltage yog hais txog 3.7V tas tus nqi, lub ntsiab nti ntawm lub tshuab sab nraud tsis muaj cov zis, kos lub thawv hluav taws xob ntawm lub tshuab hluav taws xob sab nraud hluav taws xob thaiv, thauj khoom txuas txuas, paub meej tias hloov;
Kauj ruam 5: Multimeter DC cov ntaub ntawv xeem N-COM voltage, qhov voltage dhia ntawm 30V-56V, tsis muaj teeb liab tawm tswv yim los ntawm lub tshuab puab, xyuas qhov kev twb kev txuas ntawm lub ntsiab board ntawm lub puab tshuab, paub meej tias qhov kev hloov;
Kauj Ruam 6: Cov xwm txheej saum toj no yog qhov qub, hloov COM cable cais, saib seb lub tshuab sab hauv thiab sab nraud tuaj yeem sib txuas lus li cas, kom txiav txim siab tawm ntawm txoj kab.
Lus Cim 1: Qee qhov yuam kev motherboards tuaj yeem muaj 470K resistor vulcanization lossis nyiaj teeb meem kev tsiv teb tsaws, resistor vulcanization, tus nqi hluav taws xob saum toj no tuaj yeem hloov pauv.
Lus Cim 2: Raws li qhov xwm txheej ib txwm muaj, cov ntaub ntawv multimeter DC los ntsuas qhov hluav taws xob ntawm N-COM, qhov voltage yuav nyob nruab nrab ntawm 5V-30V-56V tsis tu ncua dhia.
