Yuav ua li cas kho qhov hnyav qhov yuam kev ntawm lub ntsuas dej noo?
1. Kev hloov kho qhov hnyav ntawm qhov ntsuas dej noo
Qhov sib npaug ntawm qhov ntsuas dej noo yog qhov sib npaug ntawm qhov sib npaug, thiab nws cov qauv yog nyob rau ntawm ob rab riam qauv sib npaug, uas zoo ib yam li cov qauv sib npaug ntawm ib leeg. Nws qhov tshwj xeeb yog tias tus nqi ntawm cov khoom nws hnyav yog ib qho nqi. Lub sijhawm no, qhov nyiaj tshuav tuaj yeem lav tau tias nyob rau hauv xoom-point tshuav nyiaj li cas, uas yog, nyob rau hauv lub xeev "tsis muaj-load". Thaum 10g ua ke tus qauv hnyav yog muab tso rau rau calibration, qhov nyiaj tshuav ntawm qhov nyiaj tshuav tsis yog xoom, tab sis muaj qhov sib txawv. Qhov sib txawv tuaj yeem raug tshem tawm los ntawm kev kho qhov sib npaug. Thaum qhov sib txawv me me, kho qhov me me ntawm qhov sib npaug ntawm sab xub ntiag. , yog tias qhov sib txawv loj, lub nqaj tuaj yeem raug tshem tawm, thiab qhov sib npaug loj thallium nyob rau tom qab ntawm lub nqaj tuaj yeem hloov kho kom txog thaum qhov sib npaug ntawm qhov sib npaug. Nws yuav tsum raug sau tseg tias tom qab kev kho tiav tiav, qhov sib npaug thallium yuav tsum tau nruj. Txhawm rau tiv thaiv qhov sib npaug ntawm thallium los ntawm loosening thiab ua rau qhov sib txawv ntawm qhov hnyav qhov yuam kev kom tsis txhob muaj kev zam.
2. Kev hloov kho tus nqi faib ntawm cov ntsuas dej nrawm nrawm
Txawm hais tias cov dej noo ntawm cov khoom ntsuas los ntawm cov ntsuas dej nrawm nrawm yog qhov tseeb lossis tsis yog nyob ntawm qhov raug thiab qhov yuam kev ntawm kev faib cov nqi ntawm lub ntsuas ntsuas. Raws li ib qho tseem ceeb ntsuas kev ntsuas ntsuas, qhov kev faib tus nqi yuav tsum tau kho tom qab qhov hnyav ntawm qhov sib npaug yog hloov kho. Txheeb xyuas tus nqi kawm tiav ntawm qhov kos npe. Cov txheej txheem yog tshem tawm 1g tus qauv hnyav los ntawm lub qhov hnyav, thiab saib xyuas los ntawm qhov kev tshuaj ntsuam xyuas lub sijhawm no, qhov ntsuas kab ntawm qhov kawg ntawm lub cim yuav tsum coincide nrog lub hauv paus ntawm lub teeb screen, thiab qhov yuam kev yuav tsum tsis txhob ua. ntau dua li ± 1 division tus nqi, yog tias qhov yuam kev ntau tshaj qhov tso cai, lub nqaj ntawm qhov sib npaug yuav tsum tau muab tshem tawm, thiab tus nqi faib yuav tsum raug kho los ntawm kev hloov qhov nruab nrab ntawm lub ntiajteb txawj nqus thallium. Vim hais tias tus taw tes ntawm lub nqaj ntawm qhov sib npaug ntawm qhov ntsuas nrawm nrawm yog nce siab, thiab qhov nruab nrab ntawm lub ntiajteb txawj nqus yog nyob rau hauv qis kawg, uas yog rov qab rau txoj kev teeb tsa ntawm lub nqaj ntawm qhov sib npaug, qhov kev hloov kho ntawm nws qhov chaw nruab nrab. Lub ntiajteb txawj nqus yog opposite rau qhov zoo sib npaug. Tom qab tshem tawm cov nqaj, muab tus taw tes rau hauv qab, thaum tus nqi faib loj, tig qhov nruab nrab ntawm lub ntiajteb txawj nqus counterclockwise, uas yog, nce qhov kev ncua deb ntawm qhov nruab nrab ntawm lub ntiajteb txawj nqus thiab fulcrum hniav; thaum tus nqi faib me me, tig qhov nruab nrab ntawm lub ntiajteb txawj nqus clockwise kom txo qhov kev ncua deb ntawm qhov nruab nrab ntawm lub ntiajteb txawj nqus thiab lub fulcrum hniav, kho tus nqi kawm tiav kom tau raws li qhov yuav tsum tau ua, thiab tom qab ntawd zawm qhov chaw ntawm lub ntiajteb txawj nqus thallium.
Tom qab kho qhov hnyav qhov yuam kev thiab faib tus nqi ntawm cov ntsuas dej noo, qhov kev tshawb nrhiav ib txwm tuaj yeem ua tiav. Nyob rau tib lub sijhawm, txhawm rau txhawm rau txhawm rau txheeb xyuas qhov tseeb, yav tom ntej siv, nws yuav tsum tau ntsuas tsis tu ncua.
