Miiska calaamada badan ee mitirka: sharaxaad
Tusmo
Waa maxay multimeter-ka?
Multimeter-ku waa aalad wax lagu cabbiro oo aasaasi ah oo cabbiri karta sifooyinka korantada ee kala duwan sida danab, caabbinta, iyo hadda. Qalabka waxaa sidoo kale loo yaqaan volt-ohm-milimitir (VOM) sababtoo ah waxay u adeegtaa sida voltmeter, ammeter, iyo ohmmeter.
Noocyada mitirka badan
Qalabkan cabbiraadda waxa ay ku kala duwan yihiin cabbirka, sifooyinka iyo qiimayaasha waxaana loogu talagalay in lagu qaado ama lagu isticmaalo miis iyadoo ku xidhan isticmaalkooda loogu talagalay. Noocyada multimeter-yada waxaa ka mid ah:
- Analog multimeter (halkan ka baro sida loo akhriyo)
- Mitiimitir dijitaal ah
- Fluke multimeter
- Isku dheji multimeter
- Multimeter oo toos ah
Multimeter-ka waa mid ka mid ah qalabka wax lagu cabbiro ee inta badan la isticmaalo waayadan. Si kastaba ha ahaatee, bilawga inta badan way ku adag tahay inay aqoonsadaan calaamadaha ku yaala multimeterka. Maqaalkan, waxaan ku tusi doonaa sida loo aqoonsado jilayaasha multimeter-ka.
Inkasta oo noocyada kala duwan ee multimeter-yada laga heli karo suuqa, dhammaantood waxay isticmaalaan nidaam calaamad isku mid ah. Calaamadaha waxaa loo qaybin karaa qaybaha soo socda:
- Daar/dami icon
- icon albaabka
- Astaanta korantada
- Astaanta hadda
- Astaanta iska caabinta
Macnaha calaamadaha ku yaal multimeter-ka
Calaamadaha ku jira multimeterka waxaa ka mid ah:
| Calaamadda | Shaqada nidaamka |
| batoonka Qabo | Waxay caawisaa in la duubo oo la kaydiyo xogta la cabbiray. |
| Badhan dami/dami | Fur, dami |
| Dukumiintiga | Waxay u taagan tahay Common oo had iyo jeer waxay ku xiran tahay dhulka (Ground) ama cathode wareegga. Dekadda COM inta badan midabkeedu waa madow, sidoo kale waxa ay inta badan ku xidhan tahay baadhitaan madow. |
| dekedda 10A | Tani waa deked gaar ah, oo badanaa loogu talagalay in lagu cabbiro qulqulka sare (> 200 mA). |
| mA, μA | Deked cabbir oo hooseeysa. |
| mA ohm dekedda | Kani waa dekedda uu baaritaanka cas inta badan ku xiran yahay. Dekeddani waxay cabbiri kartaa hadda (ilaa 200mA), danab (V), iyo iska caabin (Ω). |
| oCVΩHz dekedda | Tani waa deked ku xidhan sunta rasaasta cas. Waxay kuu ogolaanaysaa inaad cabbirto heerkulka (C), danab (V), iska caabin (), soo noqnoqoshada (Hz). |
| Dekedda dhabta ah ee RMS | Caadi ahaan waxay ku xiran tahay siliga cas. Si loo cabbiro xididka runta ah waxay ka dhigan tahay halbeeg labajibbaaran (RMS run ah). |
| Dooro badhanka | Waxay ka caawisaa in ay kala beddelaan hawlaha. |
| dhalaalaya | Hagaajin dhalaalka bandhigga. |
| danabka dhaxe | Hadda beddelka Alaabooyinka qaarkood waxaa si fudud loogu tilmaamaa sida A. |
| danabka DC | D.C |
| Hz | Cabbir inta jeer ee |
| DHAQAN | Wareegga cabbirka. Cabbir awoodda hadda jirta. Hubi sii socoshada, wareegga gaaban (Check Continuity Check). |
| badhanka calaamada | Tijaabada Diode (Tijaabada Diode) |
| hFE | Tijaabada transistor-transistor |
| NCV | Shaqada soo galitaanka hadda ee aan lala xidhiidhin |
| Badhanka REL (qaraabo) | Deji qiimaha tixraaca Waxay caawisaa isbarbardhigga iyo xaqiijinta qiyamka la cabbiray ee kala duwan. |
| badhanka RANGE | Dooro aagga cabbiraadda ku habboon. |
| MAX/MIN | Ku kaydi ugu badnaan iyo qiimaha gelinta ugu yar; Ogeysiinta dhawaaqa marka qiimaha la cabiray uu dhaafo qiimaha la kaydiyay. Kadibna qiimahan cusub ayaa dib loo qoraa. |
| Astaanta Hz | Waxay tilmaamaysaa inta jeer ee wareeg ama qalab. |
Isticmaalka mitirka badan?
- Waxaa loo isticmaalaa in lagu cabbiro danab, tusaale ahaan: cabbir DC hadda, AC hadda.
- Ku cabbir iska caabbinta danab joogto ah, hadda iyo ohmmeter yar.
- Loo isticmaalo in si degdeg ah loo cabbiro wakhtiga iyo inta jeer. (1)
- Awood u leh inuu baaro dhibaatooyinka wareegga korantada ee baabuurta, hubiyo baytariyada, beddelka baabuurta, iwm. (2)
Maqaalkani waxa uu bixiyaa dhammaan qeexitaannada calaamadaha tixraaca si loo aqoonsado dhammaan calaamadaha lagu muujiyey mitirka badan. Haddii aanu mid seegno ama aanu hayno talo, xor u noqo inaad noo soo dirto iimaylka.
