Yuav siv tus cwj mem digital li cas?
Teb: Txhawm rau siv cov ntawv ntsuas digital kom raug, koj yuav tsum paub cov ntsiab lus hauv qab no:
(1) Khawm piav qhia:
(Ib tus yuam sij) DIRECT, ncaj qha ntsuas khawm (nyob deb ntawm lub vijtsam LCD), uas yog, thaum kov cov kab ncaj qha nrog tus cwj mem, thov nias lub pob no.
(B yuam sij) QIB, induction ntsuas khawm (ze rau ntawm lub vijtsam LCD), uas yog, thaum kov cov kab nrog tus cwj mem, thov nias lub pob no.
Lus Cim: Txawm hais tias tus cwj mem luam tawm li cas, thov nco ntsoov tias tus yuam sij deb ntawm lub vijtsam LCD yog qhov ntsuas ncaj qha; tus yuam sij ze rau lub LCD yog tus yuam sij sensor.
(2) Lub ntsuas hluav taws xob digital ntsuas ntsuas yog tsim nyog rau kev kuaj ncaj qha AC thiab DC tam sim no ntawm 12 txog 250 V thiab tsis ncaj qha txhawm rau txheeb xyuas cov kab nruab nrab, kab theem thiab qhov tawg ntawm AC lub zog. Nws tseem tuaj yeem ntsuas qhov txuas ntxiv ntawm cov khoom siv hluav taws xob uas tsis muaj hluav taws xob.
(3) Direct detection:
① Tus lej kawg yog qhov ntsuas tus nqi hluav taws xob.
② Thaum tus nqi siab tso tawm tsis tau txog 70%, tus nqi qis qis yuav tshwm sim.
③ Thaum ntsuas qhov hluav taws xob ncaj qha, kov lwm tus ncej nrog koj txhais tes.
(4) Indirect detection: Nias thiab tuav lub khawm B thiab coj tus cwj mem los ze rau ntawm lub hwj chim qaum. Yog hais tias lub hwj chim qaum raug them, lub cim hluav taws xob siab yuav tshwm rau ntawm cov zaub ntawm tus cwj mem.
(5) Kev kuaj pom qhov tawg: Nias thiab tuav tus yuam sij B thiab txav mus ntev raws cov hlau. Lub ntsiab lus uas tsis muaj zaub nyob rau hauv lub qhov rais zaub yog lub breakpoint.
Kev faib cov cwj mem hluav taws xob
Cov qhab nia raws li qib ntsuas voltage:
1. High-voltage test cwj mem: siv rau kev ua haujlwm ntawm 10kv thiab siab dua. Nws yog ib qho cuab yeej ntsuas txhua hnub rau cov neeg siv hluav taws xob.
2. Tsawg-voltage xeem cwj mem: siv rau kev kuaj xyuas cov khoom siv hauv cov haujlwm nrog cov kab hluav taws xob ntawm 500V thiab hauv qab no.
3. Tsis muaj zog tam sim no tus cwj mem: siv los kuaj cov khoom siv hluav taws xob. Qhov ntsuas hluav taws xob dav dav yog 6v--24v. Rau kev yooj yim ntawm kev siv, qhov kawg ntawm tus cwj mem hluav taws xob feem ntau muaj cov hlau lead nrog cov clip.
Raws li kev tiv tauj:
1. Tiv tauj xeem tus cwj mem: ib lub cuab yeej tshawb nrhiav uas tau txais cov cim hluav taws xob los ntawm kev tiv tauj cov khoom raug them. Nws yog feem ntau zoo li tus ntsia thawv ntsia hlau thiab tuaj yeem siv rau ob qho tib si ntsuas cwj mem thiab cov ntsia hlau. Nws tseem yog hom cwj mem thiab qhia cov ntaub ntawv ntsuas ncaj qha rau ntawm lub qhov rais LCD.
2. Inductive test cwj mem: Siv kev ntsuas inductive, tsis tas yuav tsum muaj kev sib cuag ntawm lub cev. Nws tuaj yeem kuaj xyuas qhov hluav taws xob ntawm cov kab tswj, tus neeg xyuas pib thiab lub qhov (socket) lossis tshawb xyuas qhov chaw tawg ntawm cov hlau. Kev nyab xeeb ntawm tus kheej ntawm cov neeg ua haujlwm soj ntsuam tuaj yeem lav tau qhov loj tshaj plaws.
