Yadda za a daidaita oscilloscope: jagorar mataki zuwa mataki

Oscilloscope wani muhimmin kayan lantarki ne da ake amfani da shi a fagage daban-daban don dalilai daban-daban.

Yayin da manufar oscilloscope ya iyakance ga auna siginar lantarki da kuma nazarin yadda sigina ke canzawa a kan lokaci, kayan aikin kuma yana da amfani lokacin magance matsalolin lantarki. 

Koyaya, sakamakon da kuke samu tare da oscilloscope ya dogara da yadda aka daidaita shi. Kyakkyawan oscilloscope mai ƙima yana ba da ingantaccen sakamako da za ku iya dogara da shi, yayin da kayan aiki mara kyau zai gurbata sakamakon ku.

Don haka, kuna son daidaita oscilloscope. Koyaya, babbar matsalar ita ce yadda ake daidaita oscilloscope. 

Wannan labarin yana ba da jagorar mataki-mataki don daidaita oscilloscope.

Menene calibration?

Calibration yawanci kwatanta na'urorin aunawa guda biyu ne. A cikin daidaitawa, na'ura ɗaya tana ba da ma'auni, kuma ɗayan na'urar dole ne ta dace da ƙa'idar da aka bayar. 

Daidaitawa yana bincika bambanci a sakamakon auna na'urorin auna guda biyu kuma yana tabbatar da cewa ƙarancin daidaitattun na'urorin biyu ya dace da ma'aunin tunani wanda madaidaicin ya bayar. Wannan tsari yana nufin inganta daidaito na kayan aikin, wanda ke ba da sakamako mai kyau yayin jarrabawa.

Ana yin gyare-gyaren kasuwanci na yau da kullun ta amfani da ƙa'idodin tunani da hanyoyin masana'anta. Ma'auni yawanci aƙalla sau huɗu ya fi daidai fiye da na'urar ƙira.

Don haka, yin amfani da sabon kayan aiki yana ba da sakamako iri ɗaya kamar sauran kayan aikin daidai, muddin ana amfani da su ƙarƙashin yanayi iri ɗaya.

Don oscilloscopes, oscilloscope calibration shine tsarin daidaita oscilloscopes don samun sakamako a cikin kewayon yarda. 

Yadda ake daidaita oscilloscope

Yayin da oscilloscopes ya zo a cikin nau'o'i daban-daban da nau'o'i daban-daban, kuma mafi kyawun tsarin daidaitawa na oscilloscopes daban-daban ya bambanta, wannan jagorar gabaɗaya zai gaya muku yadda ake kammala aikin.

Ta hanyar karanta littafin koyarwar oscilloscope ɗin ku, zaku kuma ƙarin koyo game da daidaita kayan aikin ku na musamman.

Anan ga matakan gabaɗayan don daidaita oscilloscope:

1. Saita duk sarrafawa zuwa al'ada

Duba duk sarrafawa kuma saita su zuwa matsayi na al'ada. Kodayake wannan saitin ya bambanta ta nau'in oscilloscopes, yawancin oscilloscopes suna buƙatar ka tsakiya duk bugun bugun kira kuma ƙara duk maɓallai. 

2. Kunna oscilloscope

Idan kuna da tsohon kera CRT, ba shi ƴan mintuna don dumama.

3. Saita ikon VOLTS/DIV zuwa saitunan da kuke so.

Kodayake zaka iya zaɓar ƙimar da ake so don ma'aunin VOLTS/DIV, yawanci yana da kyau a saita shi zuwa 1 don dalilai na daidaitawa. Sanya shi zuwa 1 yana ba da damar oscilloscope don nuna volt ɗaya a kowane rabo a tsaye. 

4. Saita TIME/DIV zuwa mafi ƙarancin ƙima

Wannan saitin, yawanci 1 ms, yana ba wa oscilloscope rarrabuwa a kwance don wakiltar tazarar lokaci. Bi wannan ta hanyar jujjuya bugun bugun kira ɗaya a lokaci ɗaya, a hankali canza digon zuwa madaidaiciyar layi.

5. Juya maɓallin kunnawa zuwa matsayi "Auto".

Wannan yana sauƙaƙa don lura da yanayin motsi akan allon. Trigger Auto yana taimakawa kafa wuri gama gari akan siginar igiyar ruwa don daidaita alamar. Idan ba tare da wannan ba, siginar yana motsawa kuma yana da wuyar gani. 

6. Haɗa oscilloscope zuwa siginar shigarwa

Lokacin daidaita oscilloscope, yana da mahimmanci a haɗa shi zuwa siginar shigarwa. Fara da haɗa bincike zuwa kayan aiki. Idan kuna da jacken shigarwa da yawa, haɗa firikwensin zuwa jack mai lakabin A. 

Oscilloscopes yawanci suna da binciken shigar da bayanai da waya ta ƙasa. Binciken shigarwa yawanci ana haɗa shi da siginar shigarwa, kuma ana haɗa wayar ƙasa zuwa kowane wuri na ƙasa a cikin kewaye. 

7. Haɗa binciken zuwa mai haɗin daidaitawa na oscilloscope.

Wannan zai samar da samfurin raƙuman raƙuman ruwa da ake buƙata don daidaita kayan aikin ku. Wasu oscilloscopes suna da tashoshi biyu, yawanci 0.2V da 2V. Idan kayan aikin ku yana da tashoshi biyu, yi amfani da 2V don wannan dalili. 

Sanya binciken a kan tashar daidaitawa na iya zama da wahala, musamman idan yana da ƙarshen nuni. Kodayake binciken gwajin faifan alligator yana da sauƙin sanyawa akan tashar daidaitawa, ƙila ba za ku fahimci yadda ake amfani da binciken da aka nuna ba.

Sanya binciken da aka nuna akan tashar ta hanyar tura tip ta cikin ƙaramin rami a ƙarshen tashar daidaitawa.

Kuna so ku tambayi idan ya zama dole don haɗa waya ta ƙasa. Lokacin amfani da oscilloscope a cikin da'irar lantarki, yana da mahimmanci a haɗa ƙasan oscilloscope zuwa tushen ƙasa da aka haɗa da ƙasa. Wannan shine don hana haɗarin girgiza wutar lantarki da lalacewa ga kewaye.

Koyaya, ba a buƙatar haɗin wayar ƙasa don dalilai na daidaitawa. 

8. Saita igiyar ruwa

Idan kalaman murabba'in da aka nuna bai dace akan allon ba, koyaushe zaka iya daidaita shi ta amfani da sarrafa TIME/DIV da VOLTS/DIV. 

Sauran sarrafawa masu amfani sun haɗa da sarrafa Y-POS da X-POS. Yayin da ikon Y-POS yana taimakawa tsakiyar lanƙwasa a kwance, X-POS yana ɗaukar lanƙwasa a tsaye.

Yanzu zaku iya amfani da oscilloscope don auna siginar lantarki da samun ingantaccen sakamako. 

Me yasa zan daidaita oscilloscope na?

Ee, dole ne ku daidaita oscilloscope. Kamar yadda yake tare da sauran kayan aikin lantarki, daidaita oscilloscope yana taimakawa tabbatar da cewa ya cika ka'idojin da aka yarda da su kuma sakamakon da yake samarwa shine na sauran injiniyoyi da masana kimiyya. 

Don haka, tabbatar da oscilloscope ɗin ku an daidaita shi ta hanyar duba shi akai-akai. Wannan zai sa sakamakon gwajin ku ya zama abin dogaro kuma ya ba ku kwarin gwiwa yayin ɗaukar awo da kayan aiki. Musamman lokacin amfani da oscilloscope don sauti, duk saituna dole ne su kasance daidai.

Sau nawa ya kamata a daidaita oscilloscopes?

Yawan oscilloscope calibration ya dogara da nau'in oscilloscope da kuke da shi. Koyaya, matsakaicin shawarar tazarar daidaitawa shine watanni 12.

Ko da yake wannan na iya bambanta dangane da nau'i da samfurin oscilloscope, yanayin gwajin kuma yana taka muhimmiyar rawa a sau nawa ana daidaita oscilloscope. 

Don haka, kuna son kimanta yanayin gwajin ku don ganin yadda yake shafar daidaiton oscilloscope ɗin ku.

Abubuwa da yawa suna da alhakin sakamako mara kyau tare da oscilloscope. Misali, abubuwa kamar zafi mai yawa, girgiza, canjin zafin jiki, da ƙura na iya shafar daidaiton oscilloscope, yana rage tazarar daidaitawa. Hakanan

Ana faɗin haka, kuna son ci gaba da bin diddigin sakamakonku kuma ku bincika idan daidai ne. Sakamakon gwajin ku wanda ya saba wa daidaitattun sakamakon ya isa nuni da cewa kayan aikin ku na buƙatar daidaitawa, ba tare da la'akari da lokacin da kuka ƙirƙira shi ba.
