Sida loo cabbiro Voltage DC Multimeter (Hagaha bilowga)

Voltage waxaa laga yaabaa inay tahay cabbirka multimeterka ugu fudud oo inta badan la akhriyo. Halka akhriska korantada DC ay u ekaan karto mid fudud jaleecada hore, helitaanka akhris wanaagsan waxay u baahan tahay aqoon qoto dheer oo ku saabsan shaqadan keliya.

Marka la soo koobo, waxaad ku cabbiri kartaa danabka DC-ga oo leh multimeter adiga oo raacaya tillaabooyinkan. Marka hore, u beddel garaaca danabka DC. Kadibna sunta rasaasta madaw geli jaakadda COM ka casna waxa uu u horseedaa godka V Ω. Ka dibna ka saar dipstick casaanka ah marka hore ka dibna dipstick madow. Kadibna ku xidh tilmaamaha tijaabada wareegga. Hadda waxaad akhrin kartaa cabbirka danabka ee shaashadda. 

Haddii aad tahay bilow oo aad rabto in aad barato sida loo cabbiro danabka DC-ga multimeter-labadaba multimeter-ka dhijitaalka ah iyo analoogga-waxaad timid meeshii saxda ahayd. Waxaan ku bari doonaa habka oo dhan, oo ay ku jiraan falanqaynta natiijooyinka.

Waa maxay danab joogto ah?

Si loo fahmo, danab DC waa qaab gaaban oo ka mid ah ereyga "DC voltage" - danab awood u leh inuu soo saaro hadda si toos ah. Dhanka kale, danab beddelka ayaa awood u leh inuu soo saaro tamarta beddelka ah.

Guud ahaan, DC waxaa loo isticmaalaa in lagu qeexo nidaamyada leh polarity joogto ah. Si kastaba ha ahaatee, macnaha guud, DC waxaa inta badan loo isticmaalaa in lagu tixraaco tiro aan xayndaabkoodu si joogto ah isu bedelin, ama tiro leh inta jeer ee eber. Tirooyinka sida joogtada ah u beddela polarity ee leh soo noqnoqoshada togan waxaa loo yaqaana alternating current.

Farqiga ka iman kara danabka/kharashka unugga ee u dhexeeya labada boos ee beerta korantada waa danab. Dhaqdhaqaaqa iyo joogitaanka walxaha la dallacay (electrons) waxay soo saaraan tamar koronto. (1)

Farqiga iman kara wuxuu yimaadaa marka elektaroonnada ay u kala guuraan laba dhibcood - laga bilaabo barta awoodda hoose ilaa barta awoodda sare. AC iyo DC waa laba nooc oo tamar koronto ah. (2)

Danab ka soo jeeda DC waa waxa aan halkan kaga hadlayno - danabka DC.

Tusaalooyinka ilaha DC waxaa ka mid ah baytariyada, baallayaasha cadceedda, kulaylaha, koronto dhaliyayaasha DC, iyo korantada DC si loo saxo AC.

Sida loo cabbiro danabka DC multimeter (dijital)

1. U beddel garaaca danabka DC. Haddii DMM kaaga uu la yimaado millivolts DC oo aanad garanayn midka aad dooranayso, ku bilaw danabka DC maadaama lagu qiimeeyay danab sare.
2. Kadib geli baaritaanka madow ee isku xiraha COM.

3. Tijaabooyinku waa inay galaan gudaha V Ω jack. Markaad tan sameyso, marka hore ka saar dipstick cas ka dibna dipstick madow.

3. Talaabada afraad waa in lagu xidho shaybaarada tijaabada wareegga (baaritaannada madow ee barta tijaabada polarity-ka taban iyo baarayaasha gaduudan ee barta tijaabada polarity-ga togan).

Ogow. Waa inaad la socotaa in mitirada-mitirka casriga ah intooda badan ay si toos ah u ogaan karaan polarity. Marka la isticmaalayo multimeter-ka dhijitaalka ah, siliga cas waa in aanu taaban terminalka togan, siliga madowna waa in aanu taaban teerminalka taban. Haddii baarayaashu taabtaan terminal ka soo horjeeda, calaamad xun ayaa ka soo muuqan doonta shaashadda.

Markaad isticmaalayso multimeter-ka analoogga ah, waa inaad hubisaa in raadadyadu ay taabayaan marinnada saxda ah si aanay u dhaawicin multimeterka.

5. Hadda waxaad akhrin kartaa cabbirka danabka ee shaashadda.

Talooyin waxtar leh oo ku saabsan Cabbirka Voltage DC ee DMM

1. DMM-yada casriga ah waxay inta badan leeyihiin kala duwanaansho otomaati ah si caadi ah, taas oo ku xidhan shaqada lagu muujiyay garaaca. Waxaad bedeli kartaa kala duwanaanta adiga oo riixaya badhanka "Range" dhowr jeer ilaa aad ka gaarto xadka la rabo. Cabbirka korantada ayaa laga yaabaa inuu ku dhaco xadka dejinta millivolt DC hoose. Ha welwelin. Ka saar shaybaarrada tijaabada, u beddel garaaca si aad u akhrido millivolts DC, dib u geli shaybaarrada tijaabada, ka dibna akhri cabbirka danabka.
2. Si aad u hesho cabbirka ugu xasiloon, taabo badhanka "qabta". Waxaad arki doontaa ka dib marka cabbirka tamarta la dhammeeyo.
3. Riix badhanka "MIN/MAX" si aad u hesho cabbiraadda korantada DC ee ugu hooseeya uguna sarreeya, taabo badhanka "MIN/MAX". Sug dhawaaq mar kasta oo ay DMM diiwaangeliso qiimaha danab cusub.
4. Haddii aad rabto inaad u dejiso DMM qiimo hore loo go'aamiyay, taabo "REL" (Qaraabo) ama "?" (Delta) badhamada. Bandhigu wuxuu muujin doonaa cabbirada danabka ka hooseeya iyo ka sarreeya qiimaha tixraaca.

Sida loo cabbiro danab DC ah oo leh multimeterka analoogga ah

Raac tillaabooyinkan fudud:

1. Riix badhanka "ON" ee mitirkaaga si aad u shido.
2. U rog guntimaha multimeterka booska "V"._DC» - danabka DC. Haddii multimeter-kaaga analogga ah uusan lahayn "V_{GOBOLKA COLUMBIA,}Iska hubi haddii uu jiro V oo leh xariiq toosan oo 3 dhibcood ah oo u rog buro dhankiisa.

3. Ku sii wad si aad u dejiso baaxadda, kaas oo ah in uu ka weyn yahay tirada korantada ee tijaabada la filayo.
4. Haddii aad ku shaqaynayso danab aan la garanayn, tirada go'an waa inay ahaataa mid weyn intii suurtogal ah.
5. Ku xidh sunta rasaasta madow ee COM jaakadda iyo sunta cas ee VΩ jaakadda (gaar ahaan kan VDC ku dul yaal).
6. Ku dheji baaritaanka madow barta korantada taban ama hoose, baaritaanka casna dhig barta korontada togan ama sare.
7. Si aad u leexiso ugu badnaan, kaas oo gacan ka geysanaya hagaajinta saxnaanta, hoos u dhig tirada tamarta.
8. Hadda qaado akhrinta VDC oo ka taxaddar inaadan akhriyin VAC.
9. Kadib markaad dhameysato akhrinta, ka saar baaritaanka cas marka hore ka dibna baaraha madow.
10. Demi multimitirka ka dibna deji qiyaasta ugu badan si aad uga hortagto burbur haddii ay dhacdo dib u isticmaal degdeg ah.

Si ka duwan multimeter-ka dhijitaalka ah, multimeter-ka analoogga ah kama digayo polarity rogan, kaas oo dhaawici kara multimeterka. Ka digtoonow, had iyo jeer ixtiraam polarity.

Waa maxay xaaladda culeyska xad dhaafka ah iyo goorma ayay dhacdaa?

Waxaa jirta sabab wanaagsan oo lagugula talinayo inaad doorato kala duwanaansho koronto oo ka sarreeya qiimaha la filayo. Doorashada qiime hoose waxay keeni kartaa culeys xad dhaaf ah. Mitirku ma cabbiri karo danab marka uu ka baxsan yahay cabbirka cabbirka.

Dhanka DMM, waxaad ogaan doontaa inaad la tacaaleyso xaalad culeyska xad dhaafka ah haddii DMM ay ku akhrido "meel ka baxsan", "OL" ama "1" shaashadda. Ha argagixin marka aad hesho tilmaame culays badan. Ma dhaawici karto ama dhaawici karto multimeter-ka. Waxaad ka gudbi kartaa xaaladan adiga oo ku kordhinaya kala duwanaanshiyaha xulashada xulashada ilaa aad ka gaarto qiimaha la filayo. Haddii aad ka shakisan tahay hoos u dhaca danab ee wareeggaaga, waxaad sidoo kale isticmaali kartaa multimeter si aad u cabbirto.

Markaad isticmaalayso multimeter-ka analoogga ah, waxaad ogaan doontaa inaad leedahay xaalad culeys badan haddii aad aragto fallaadha "FSD" Multimeter-yada analoogga ah, xaaladaha culeyska xad-dhaafka ah waa in laga fogaadaa si looga hortago waxyeellada suurtagalka ah. Ka fogow qiyaasaha danab yar ilaa aad taqaanid sida loo cabbiro tamarta.

Golaha AmaankaKa fogow dareemayaasha leh fiilooyinka jaban ama qaawan. Marka lagu daro qaladka lagu daro akhrinta cabbiraadda korantada, baarayaasha dhaawacan waxay halis u yihiin cabbirada tamarta.

Haddii aad isticmaalayso multimeter-ka dhijitaalka ah ama multimeter-ka analoogga ah, hadda waxaad garanaysaa sida multimeter-ku u cabbiro tamarta. Hadda waxaad si kalsooni leh ku cabbiri kartaa hadda.

Haddii aad si buuxda u fiirsato habka, waxaad diyaar u tahay inaad ka cabbirto korantada ilaha DC. Hadda ka cabbir danabka isha aad doorbidayso ee DC oo arag sida ay u shaqeyso.

Waxaan hoos ku taxnay dhowr casharro badan oo mitiromitir ah. Waad hubin kartaa oo aad u calaamadayn kartaa si ay hadhow u akhriyaan. Mahadsanid! Oo aan ku aragno maqaalkeena soo socda!
