Troubleshooting for Common Faults of Digital Universal Tool Microscopes
1. Txoj kev kho qhov muag tseem ceeb ntawm qhov ntsuas tsis tau teeb, feem ntau yog vim:
(1) Lub ntsuas hluav taws xob tsis muaj hluav taws xob tso tawm;
(2) Transformer fuse tshuab;
(3) Lub teeb pom kev zoo lossis kev nyeem cov teeb pom kev zoo ntawm cov kab ke kho qhov muag raug puas;
(4) Cov xov hlau nruab nrab ntawm lub ntsuas ntsuas thiab lub tshuab hloov pauv tsis raug txuas.
Qhov laj thawj tseem ceeb vim li cas lub npov digital tsis tso tawm yog:
(1) Lub hauv paus ntsuas thiab lub thawv digital cov kab hluav taws xob tsis txuas zoo;
(2) Qhov hloov ntawm lub vaj huam sib luag tom qab ntawm lub npov digital tsis qhib;
(3) Cov hlua hluav taws xob ntawm lub npov digital tsis raug ntsaws rau hauv;
(4) Lub x thiab y tswj cov teeb liab cables ntawm lub grating sensor thiab lub npov digital ntawm lub ntsuas ntsuas tsis zoo txuas;
(5) Lub thawv ntawv digital muaj qhov luv luv, qhib Circuit Court, lossis cov khoom puas.
Cov laj thawj tseem ceeb rau kev ntxhov siab lossis tsis ruaj khov ntawm tus lej kawg ntawm lub npov digital yog:
(1) Lub microcomputer tsis tau ua tiav tsis siv neeg lub hwj chim thiab tsis tau nkag mus rau qhov kev pab cuam ib txwm;
(2) Seg lossis me ntsis scanning txhaum, yuav tsum tau hloov cov ntu lossis me ntsis tsav raj;
(3) Muaj qhov chaw seismic nyob ze ntawm qhov ntsuas.
Cov laj thawj tseem ceeb rau lub tswb tam sim ntawd lossis suav tsis tau ntawm lub npov digital yog:
(1) Lub workbench txav ceev heev;
(2) Kev sib cuag tsis zoo ntawm cov teeb liab cables;
(3) Lub sijhawm pib ua haujlwm ntev dhau lawm;
(4) Qhov kev hloov pauv ntawm qhov sib txawv ntawm qhov tseem ceeb thiab pab gratings ntawm lub grating sensor ua rau lub teeb liab ntawm lub grating sensor me dhau. Ua ntej kos lub cable txuas, tom qab ntawd nias lub tswb sib txuas ua ke pib dua khawm. Yog tias lub tswb raug tshem tawm, nws qhia tau tias nws yog tshwm sim los ntawm lub rooj ua haujlwm txav nrawm dhau. Yog tias nws tsis tuaj yeem tshem tau, kho lub teeb liab grating thiab siv lub oscilloscope los xyuas. Lub waveforms ntawm ob lub grating signals yuav tsum yog sine nthwv dej, nrog lub ncov mus rau qhov siab tshaj qhov tseem ceeb tshaj 2V thiab sib npaug, thiab theem sib txawv ntawm 90 degrees. Li Shayu daim duab ntawm lub oscilloscope yog ncig.
Lub ntsiab yog vim li cas rau cov zaub tus nqi ntawm lub thawv zaub digital tshaj qhov kam rau ua yog:
Thaum txhim kho tus pas ntsuas grating, nws yuav tsum tsis txhob sib npaug mus rau lub workbench qhia rail. Tus pas ntsuas grating yuav tsum tau kho kom sib npaug rau cov kev taw qhia rail hauv x thiab y cov lus qhia, thiab qhov yuam kev yuav tsum tsis pub tshaj 10 μ m.
Tsis muaj lus teb thaum nias lub keyboard, feem ntau yog vim:
Cov keyboard scanning decoder puas lawm.
Kev ceev faj rau kev siv cuab yeej
Thaum ntsuas, lub hwj chim yuav tsum tau qhib thiab preheated rau 10 feeb.
2. Tsis txhob txav lub workbench sai heev, thiab pib thiab nres smoothly.
3. Txav mus rau qhov chaw ua haujlwm kom tsis txhob muaj kev quab yuam ntau dhau los cuam tshuam rau qhov sib txawv ntawm qhov sib txawv ntawm grating.
4. Thaum muab cov ntawv xeem, tuav nws maj mam thiab tsis txhob hnyav hnyav lossis cuam tshuam rau lub taub hau grating thiab grating kav.
5.Thaum luam ntawv, ob lub hwj chim yuav tsum tau qhib ib txhij thiab lub chaw ua haujlwm yuav tsum kaw.
6. Tus kav grating yuav tsum tau ntxuav tsis tu ncua nrog cawv thiab ether.
