Izisetshenziswa zokuhlola

Umfanekiso 1 ubonisa okokusebenza kokuhlola okudingayo ukuze ulinganise idivayisi yakho. I-DMM ethize, i-calibrator, ne-counter connections ichazwa esigabeni se-Calibration Process.

Umfanekiso 1. Ukulinganisa Ukuxhumana
Uma wenza ukulinganisa, i-National Instruments incoma ukuthi usebenzise amathuluzi alandelayo ukulinganisa idivayisi ye-AO:

• I-Calibrator-Fluke 5700A. Uma lelo thuluzi lingatholakali, sebenzisa ivolumu enembayo ephezulutagUmthombo okungenani ongu-50 ppm onembile kumabhodi angu-12- no-13-bit kanye no-10 ppm kumabhodi angu-16-bit.
• I-DMM—NI 4070. Uma lelo thuluzi lingatholakali, sebenzisa i-DMM enamadijithi amaningi angu-5.5 ngokunemba okungu-40 ppm (0.004%).
• Ikhawunta—Hewlett-Packard 53131A. Uma lelo thuluzi lingatholakali, sebenzisa isibali esinembayo esingafika ku-0.01%.
• Izintambo ze-plug-in zethusi ezishisayo ze-EMF—Fluke 5440A-7002. Ungasebenzisi izintambo zikabhanana ezijwayelekile.
• Ikhebula le-DAQ—NI lincoma ukusebenzisa izintambo ezivikelekile, njenge-SH68-68-EP ene-NI 671X/673X noma i-SH68-C68-S nge-NI 672X.
• Enye yezinsiza ezilandelayo ze-DAQ:

– I-SCB-68—I-SCB-68 iyibhulokhi yesixhumi se-I/O esivikelwe esinamatheminali angama-68 ngezikulufu ukuze kuxhunywe isignali kalula kumadivayisi we-DAQ angama-68- noma angu-100.
– I-CB-68LP/CB-68LPR/TBX-68—I-CB-68LP, CB-68LPR, ne-TBX-68 yizinsiza zokunqamula ezibiza kancane ezinamatheminali angama-68 ngezikulufu ukuze kuxhunywe kalula amasiginali wensimu ye-I/O ku-DAQ yamaphini angama-68 amadivaysi.

Ukucatshangelwa kokuhlola

Landela le mihlahlandlela ukuze ulungiselele ukuxhumana nezimo zokuhlola ngesikhathi sokulinganisa:

• Gcina ukuxhumana ku-NI 671X/672X/673X kufushane. Izintambo ezinde nezintambo zisebenza njengezimpondo, eziphakamisa umsindo owengeziwe, ongathinta izilinganiso.
• Sebenzisa intambo yethusi evikelekile kukho konke ukuxhunywa kwekhebula ocingweni.
• Sebenzisa izintambo ezisontekile ukuze uqede umsindo nokushisa.
• Gcina izinga lokushisa eliphakathi kuka-18 no-28 °C. Ukuze usebenzise imojuli kuzinga lokushisa elithile elingaphandle kwalobu bubanzi, linganisa idivayisi kulelo zinga lokushisa.
• Gcina umswakama ohlobene ungaphansi kwama-80%.
• Vumela isikhathi sokufudumala okungenani imizuzu eyi-15 ukuze uqinisekise ukuthi isifunda sokulinganisa sisezingeni lokushisa elizinzile.

Inqubo Yokulinganisa

Lesi sigaba sinikeza imiyalelo yokuqinisekisa nokulinganisa idivayisi yakho.
Inqubo Yokulinganisa Iphelileview
Inqubo yokulinganisa inezinyathelo ezine:

1. Ukusetha Kwasekuqaleni—Lungisa idivayisi yakho ku-NI-DAQmx.
2. Inqubo Yokuqinisekisa ye-AO—Qinisekisa ukusebenza okukhona kocingo. Lesi sinyathelo sikuvumela ukuthi uqinisekise ukuthi idivayisi ibisebenza ngaphakathi kwebanga elishiwo ngaphambi kokulinganisa.
3. I-AO Adjustment Procedure—Yenza ukulinganisa kwangaphandle okulungisa izilinganiso zokulinganisa idivayisi ngokuphathelene nevolthi eyaziwayo.tage umthombo.
4. Yenza okunye ukuqinisekiswa ukuze uqinisekise ukuthi idivayisi isebenza ngaphakathi kwezicaciso zayo ngemva kokulungiswa.Lezi zinyathelo zichazwe ngokuningiliziwe ezigabeni ezilandelayo. Ngenxa yokuthi ukuqinisekiswa okuphelele kwazo zonke izinhla zedivayisi kungathatha isikhathi, ungase ufise ukuqinisekisa ububanzi bezinto ozithakaselayo kuphela.

Ukusethwa Kwasekuqaleni
I-NI-DAQmx ithola ngokuzenzakalelayo wonke amadivayisi we-AO. Nokho, ukuze umshayeli axhumane nedivayisi, kufanele imiswe ku-NI-DAQmx.
Ukuze ulungiselele idivayisi ku-NI-DAQmx, qedela lezi zinyathelo ezilandelayo:

1. Faka isofthiwe yomshayeli we-NI-DAQmx.
2. Vala ikhompuyutha ezobamba idivayisi, bese ufaka idivayisi endaweni etholakalayo.
3. Faka amandla kukhompuyutha, bese uvula i-Measurement & Automation Explorer (MAX).
4. Lungiselela isihlonzi sedivayisi bese ukhetha Ukuzihlola ukuze uqinisekise ukuthi idivayisi isebenza kahle.

Qaphela Uma idivayisi ilungiswa nge-MAX, inikezwa isihlonzi sedivayisi. Ngamunye
ikholi yokusebenza isebenzisa lesi sihlonzi ukuze inqume ukuthi iyiphi idivayisi ye-DAQ ezolinganiswa.

Inqubo Yokuqinisekisa ye-AO

Ukuqinisekisa kunquma ukuthi idivayisi ye-DAQ ihlangabezana kanjani nezicaciso zayo. Ngokwenza le nqubo, ungabona ukuthi idivayisi yakho isebenze kanjani ngokuhamba kwesikhathi. Ungasebenzisa lolu lwazi ukusiza ukunquma isikhawu sokulinganisa esifanele sohlelo lwakho lokusebenza.
Inqubo yokuqinisekisa ihlukaniswe yaba imisebenzi emikhulu yedivayisi. Kuyo yonke inqubo yokuqinisekisa, sebenzisa amathebula esigabeni se-AO Device Test Limits ukuze unqume ukuthi idivayisi yakho idinga ukulungiswa.
Ukuqinisekiswa Kokukhiphayo kwe-Analog
Le nqubo ihlola ukusebenza kokukhiphayo kwe-analog. Hlola izilinganiso usebenzisa le nqubo elandelayo:

Inqubo Yokulungisa ye-AO

Sebenzisa inqubo yokulungisa i-AO ukuze ulungise ukulinganisa okukhiphayo kwe-analog. Ekupheleni kwenqubo ngayinye yokulinganisa, lezi zimo ezintsha zigcinwa endaweni yokulinganisa yangaphandle ye-EEPROM. Lawa manani avikelwe nge-password, okuvimbela ukufinyelela ngephutha noma ukuguqulwa kwanoma yiziphi izingxenye zokulinganisa zokulinganisa ezilungiswe ilabhorethri ye-metrology. Iphasiwedi ezenzakalelayo ithi NI.
Ukuze wenze ukulungisa idivayisi nge-calibrator, qedela lezi zinyathelo ezilandelayo:

1. Xhuma i-calibrator kudivayisi ngokweThebula 3.
   Ithebula 3. Ukuxhuma i-Calibrator kudivayisi

6. Nqamula i-calibrator kudivayisi.

Idivayisi manje isilinganiselwe ngokuphathelene nomthombo wakho wangaphandle.
Ngemva kokulungisa idivayisi, ungase ufune ukuqinisekisa ukusebenza kokuphuma kwe-analogi. Ukuze wenze lokhu, phinda izinyathelo ezisesigabeni Senqubo Yokuqinisekisa I-AO usebenzisa imikhawulo yokuhlola yamahora angu-24 esigabeni se-AO Device Test Limits.

Imikhawulo Yokuhlola Idivayisi ye-AO

Amathebula akulesi sigaba aklelisa imininingwane yokunemba okufanele isetshenziswe lapho uqinisekisa futhi ulungisa i-NI 671X/672X/673X. Amathebula abonisa izicaciso zakho zombili izikhawu zokulinganisa zonyaka ongu-1 kanye nehora le-24. Ububanzi bonyaka ongu-1 bubonisa ukucaciswa okufanele idivayisi ihlangabezane nakho uma sekunonyaka owodwa phakathi kokulinganisa. Uma idivayisi ilinganiselwe ngomthombo wangaphandle, amanani aboniswe kumathebula wamahora angu-24 ayizicaciso ezivumelekile.
Ukusebenzisa Amathebula
Izincazelo ezilandelayo zichaza indlela yokusebenzisa ulwazi oluvela kumathebula akulesi sigaba.
Ibanga
Ububanzi bubhekisela kumthamo omkhulu ovumelekiletaguhla lwesiginali yokuphumayo.
Iphuzu Lokuhlola
Iphuzu Lokuhlola ivolumutage inani elenzelwe izinjongo zokuqinisekisa. Leli nani lihlukaniswe libe amakholomu amabili: Indawo kanye Nenani. Indawo isho lapho inani lokuhlola lingena khona phakathi kwebanga lokuhlola. I-Pos FS imele i-positive full-scale futhi i-Neg FS imele isikali esigcwele esinegethivu. Inani libhekisela ku-voltaginani le-e elizoqinisekiswa futhi liku-volts.
Amahora angu-24
Ikholomu Yobubanzi Bamahora angu-24 iqukethe Imikhawulo Ephezulu Nemikhawulo Ephansi yenani lephoyinti lokuhlola. Okusho ukuthi, uma idivayisi ingaphakathi kwesikhawu sokulinganisa samahora angu-24, inani lephoyinti lokuhlola kufanele lehlele phakathi kwamanani omkhawulo aphezulu naphansi. Imikhawulo ephezulu naphansi iboniswa ngama-volts.
1-Unyaka Range
Ikholomu Yebanga Lonyaka Ongu-1 iqukethe Imikhawulo Ephezulu Nemikhawulo Ephansi yenani lephoyinti lokuhlola. Okusho ukuthi, uma idivayisi ingaphakathi kwesikhawu sokulinganisa sonyaka ongu-1, inani lephoyinti lokuhlola kufanele lehlele phakathi kwamanani omkhawulo aphezulu naphansi. Imikhawulo ephezulu naphansi iboniswa ngama-volts.
Izinto zokubala
Akwenzeki ukulungisa ukulungiswa kwesibali/izikhathi. Ngakho-ke, lawa manani awanaso isikhathi sokulinganisa sonyaka ongu-1 noma amahora angama-24. Kodwa-ke, iphoyinti lokuhlola kanye nemikhawulo ephezulu nephansi inikezwa ngezinjongo zokuqinisekisa.
