Calaamadaha Wareegga Multimeterka iyo Macnahooda

Multimeter-ka waxaa loo isticmaalaa in lagu cabbiro danab, caabbinta, hadda iyo sii socoshada. Waa mid ka mid ah qalabka korontada ee inta badan la isticmaalo. Waxa xigta ee la sameeyo ka dib iibka waa in la barto sida saxda ah ee loo akhriyo.

Ma haysaa multimeter-ka dhijitaalka ah laakiin ma garanaysid meel aad ka bilowdo? Waxaad timid meeshii saxda ahayd. Fadlan sii wad akhrinta si aad u ogaato wax kasta oo aad u baahan tahay inaad ka ogaato calaamadaha wareegyada multimeterka iyo macnahooda.

Calaamadaha Multimeterka waxaad u baahan tahay inaad ogaato 

Calaamadaha mitirka badan waa kuwa aad ka heli doonto jaantuska wareegga.

Waxaa ka mid ah;

1. Calaamadaha korantada ee multimeterka

Sababtoo ah multimeter-yadu waxay cabbiraan korantada tooska ah ee hadda (DC) iyo beddelka hadda (AC), waxay muujiyaan in ka badan hal calaamad. Tilmaamaha korantada AC ee multimeter-yada da'da weyn waa VAC. Wax-soo-saarayaashu waxay ka sarreeyaan V-ga moodooyinka cusub si ay u muujiyaan koronta AC.

Wixii danab DC ah, soo saarayaasha waxay saarayaan xariiq dhibco leh oo leh xariiq adag oo korkiisa ah V. Haddii aad rabto inaad ku cabbirto danabka millivolts, i.. 1/1000 ee volt, garaaca u rog mV.

2. Calaamadaha multimeter-ka iska caabinta

Calaamad kale oo wareeg ah oo badan oo ay tahay inaad ogaato waa iska caabin. Multimeter-ku wuxuu soo diraa qulqul yar oo koronto ah iyada oo loo marayo wareegga si loo cabbiro caabbinta. Xarafka Giriigga ee Omega (Ohm) waa calaamadda iska caabinta multimeter-ka. Ma arki doontid wax xariiqo ka sarreeya calaamadda iska caabinta sababtoo ah mitiriyadu ma kala soocaan iska caabbinta AC iyo DC. (1)

3. Calaamadaha multimeter-ka ee hadda jira 

Hadda waxaad u cabbirtaa si la mid ah sidaad u cabbirto danabka. Waxay noqon kartaa hadda beddelka (AC) ama hadda toos ah (DC). Ogsoonow in ampere ama ampere ay yihiin unugyo hadda jira, taas oo sharraxaysa sababta calaamadda mitirka badan ee hadda ay tahay A.

Markaad eegto multimeter-ka hadda, waxaad arki doontaa xarafka "A" oo leh xariiq mawjad ah oo ka sarreeya. Kani waa bedelka hadda (AC). Xarafka "A" oo leh laba sadar-dhalan oo adag oo korkiisa ah-wuxuu u taagan yahay hadda (DC). Marka lagu cabbirayo wakhtiga xaadirka ah multimeter, doorashooyinka la heli karo waa mA loogu talagalay milliamps iyo µA ee microamps.

Jacks iyo badhamada

DMM kastaa waxay la timaadaa laba hogaan, madow iyo casaan. Ha la yaabin haddii multimeter-kaagu leeyahay saddex ama afar xiriiriye. Wax kasta oo aad tijaabiso ayaa go'aaminaya meesha aad ku xidhayso fiilooyinka.

Halkan waa isticmaalka mid kasta;

• COM - Jack caadi waa hal madow oo kaliya. Taasi waa meesha hogaanka madow uu tago.
• A - Waa halka aad ku xidhayso fiilada cas marka aad cabbirayso ilaa 10 amperes.
• mAmkA - Waxaad isticmaashaa godkan marka aad cabbirayso xasarada xasaasiga ah ee ka yar amp marka uu multimeterku leeyahay afar saldhig.
• mAOm - Socket-ka cabbiraadda waxa ku jira danab, heerkulka iyo dareenka hadda jira haddii multimeter-kaagu uu la yimaado saddex saldhig.
• VOm - Tani waa dhammaan cabbirada kale marka laga reebo hadda.

Baro mitirka-mitirkaaga, gaar ahaan xagga sare ee bandhigga multimeterka. Ma ku aragtaa laba badhan - mid midig iyo mid bidix?

• shift - Si loo badbaadiyo meel bannaan, soosaarayaashu waxay ku meelayn karaan laba hawlood boosaska garaacista qaarkood. Si aad u gasho shaqada ku calaamadsan jaalaha, taabo badhanka Shift. Badhanka Shift-ga jaalaha ah waxa laga yaabaa ama ma yeelan karo calaamad. (2)
• Qabo - taabo batoonka haysashada haddii aad rabto inaad qaboojiso akhrinta hadda si aad mar dambe u isticmaasho.

Si loo soo koobo

Waa inaadan wax dhib ah kala kulmin helitaanka akhrinta saxda ah ee DMM. Waxaan rajaynaynaa in ka dib markaad akhrido macluumaadkan faa'iidada leh, aad dareento inaad si cadaalad ah u taqaanid calaamadaha multimeterka.
