Maverengero eAnalog Multimeter Kuverenga (Matanho mana-Nhanho)

Unogona kubvunza kuti nei uchifanira kuziva mashandisiro eA/D multimeter muzera rino redhijitari.

Mundima yekuongorora zvemagetsi, analog multimeters chishandiso chakavimbika. Nyanzvi dzichiri kushandisa analog metres kunetsa mune dzimwe nzvimbo nekuda kwekurongeka kwavo uye kutendeuka kwechokwadi kweRMS tsika.

Ndichataura zvakawanda pazasi.

Nzira yekuverenga analog scale

Chiyero cheanalogi chine mitsetse yakawanda uye nhamba. Izvi zvinogona kuvhiringa kune vanotanga, saka pano iwe uchadzidza maitiro ekutanga ekuverenga chiyero nemazvo:

1. Unogona kushandisa ohmic chiyero (mutsetse wepamusoro Ω) kuverenga kuramba kubva kuruboshwe kuenda kurudyi. Iwe unofanirwa kuwanza kuyerwa kwechiyero nechiyero chakasarudzwa zvichibva pane yakatarwa. Kana huwandu hwako huri 1 kΩ uye chinongedzo chakadzikama pa5, kuverenga kwako kuchaita 5 kΩ.
2. Iwe unofanirwa kuita span kugadzirisa nenzira imwechete kune ese chiyero kuyerwa.
3. Iwe unogona kuyera voltage renji uye ikozvino pachiyero pazasi pe ohmic chiyero. DC voltage uye zvazvino zvinoyerwa padivi peiyo ohmic chiyero pamutsetse mutema. Mutsara mutsvuku nguva dzose unomiririra zviyero zve AC. Izvo zvakakosha kuyeuka kuti iwe unofanirwa kuongorora yazvino uye voltage data kubva kurudyi kuenda kuruboshwe.

Kuti uverenge analog mita kuverenga, tevera matanho aya:

1 Step: Batanidza analog multimeter kune inotungamira bvunzo. Shandisa zvinotevera zvigadziriso kuyera huwandu hwakasiyana:

Shandisa makesi:

• Voltage kuyerwaOngorora: Kuyera voltage, unofanirwa kuseta mita kune ACV (alternating current voltage) kana DCV (direct current voltage) renji, zvichienderana nerudzi rwevolti iri kuyerwa.
• Kuyera ikozvinoCherechedza: Kuyera ikozvino, unofanira kuseta mita kune ACA (AC) kana DCA (Direct Current) renji, zvichienderana nekuyerwa kwazvino.
• Kuramba kuyerwa: Iwe waizoisa mita kune iyo ohm (ohm) renji.
• Kuenderera mberi kwekuedza: Kuti uedze kuenderera mberi, unofanirwa kuseta mita kune yekuenderera bvunzo renji, inowanzo ratidzwa nechiratidzo chakadai se diode kana mutauri.
• Kuongorora transistorsOngorora: Iwe unofanirwa kuseta mita kune iyo hFE (transistor kuwana) renji kuti uedze ma transistors.
• Kuongorora CapacitorsA: Kuti uedze ma capacitors, unofanirwa kuseta mita kune capacitance range (uF).
• Diode testCherechedza: Kuti uedze madhiodhi, unofanira kuisa mamita kune diode test range, inowanzoratidzwa nechiratidzo chakadai se diode kana delta.

2 Step: Batanidza test probes kune chinhu chinoyerwa mune yega yega gadziriso uye tarisa kuyerwa kuverengwa. Tichashandisa DC voltage monitoring semuenzaniso munhaurirano iyi.

3 Step: Isa bvunzo inotungamira mumativi maviri ebhatiri reAA (inenge 9V). Zvichienderana nemhando yakasarudzwa, chinongedzo chinofanira kuchinjika pachiyero. Museve unofanirwa kuva pakati pe8 ne10 pachikero kana bhatiri rako rakazara. 

4 Step: Shandisa nzira imwe chete kuyera huwandu mumagadzirirwo akasiyana.

Sezvambotaurwa, kusarudzwa kwemhando uye kuwanda kwakakosha pakuverenga kwakaringana analog. (1)

Semuenzaniso, kana iwe uchiyera voltage yebhatiri yemotokari neA / D multimeter, huwandu hunofanira kunge hwakakura. Iwe unozofanirwa kuita kudzokorora kuri nyore kuti uverenge yekupedzisira kuburitsa.

Kana DC yako voltage renji iri 250V uye tsono iri pakati pe50 ne100, voltage inenge iine 75 volts zvichienderana nenzvimbo chaiyo.

Nhanganyaya kune panel

Kunzwisisa pani yemuchina kwakakoshawo pakuverenga analog multimeter. Izvi ndizvo zvaunofanira kuziva:

• Volt (B): chikamu chemagetsi chinogona kusiyana kana electromotive simba. Inoyera voltage, mutsauko wekugona kwemagetsi pakati pemapoinzi maviri mudunhu.
• Amplifiers (A): Chikamu chemagetsi emagetsi. Inoshandiswa kuyera kuyerera kwechaji yemagetsi mudunhu.
• Ohm (Ohm): Chikamu chekupikisa magetsi. Inoshandiswa kuyera kushorwa kwechinhu kana chikamu chedunhu.
• madiki emvura (µA): Chikamu chemagetsi chazvino chakaenzana nemirioni imwe yeampere. Inoyera madiki madiki, senge mune transistor kana chimwe chidiki chemagetsi chikamu.
• kilo (kΩ): ​​Chikamu chemagetsi kuramba chakaenzana ne1,000 Ω. Iyo inoyera yakakwira mwero wekupokana, semuenzaniso mune resistor kana imwe passive circuit element.
• megomms (mΩ): Chikamu chekupikisa magetsi chakaenzana nemiriyoni ohms. Iyo inoyera yakakwira zvakanyanya mazinga ekupikisa, senge muyedzo yekudzivirira kana imwe chiyero chakasarudzika.
• sitiroko inomirira AC voltage uye DCV inomirira DC voltage.
• Kupindirana (AC) imagetsi anopota achichinja nzira. Iyi ndiyo mhando yemazuva ano inowanzoshandiswa mudzimba uye mumaindasitiri emagetsi masisitimu uye ine frequency ye50 kana 60 Hz (hertz) munzvimbo zhinji dzepasi.
• Direct current (DC) igetsi rinoyerera richienda kune rimwe divi. Inowanzoshandiswa mumaseketi emagetsi nemidziyo yakadai semabhatiri uye solar panels.
• sitiroko и CVD zviyero zvinoyera mutsauko unokwanisa pakati pemapoinzi maviri mudunhu. AC voltage zviyero zvinoshandiswa kuyera AC voltage uye DC zviyero zvemagetsi zvinoshandiswa kuyera DC voltage.

Analog multimeter inogona zvakare kuve nezvimwe zviverengero kana zvikero pane dial kana sikero, zvinoenderana nemamita chaiwo maitiro uye kugona. Izvo zvakakosha kutarisa kune bhuku rekushandisa kana mirairo yeiyo chaiyo multimeter iri kushandiswa kunzwisisa zvinoreva izvi zvakakosha.

Mukona yezasi yekuruboshwe ye multimeter, iwe unofanirwa kuona kwekuisa ma probes.

Iwe unogona ipapo kuwana dzimwe sarudzo kuburikidza nemachiteshi ari pazasi kurudyi kona. Paunenge uchida kutenderedza polarity yechiyero, sarudzo ye polarity switch inouya inobatsira. Iwe unogona kushandisa yepakati switch kuti usarudze iyo yakayerwa kukosha uye yaunoda renji.

Semuenzaniso, itendeutse kuruboshwe kana iwe uchida kuyera voltage renji (AC) ine analog multimeter.

Mazano uye mazano akakosha

• Paunenge uchishandisa analog multimeters, sarudza rakakodzera renji kune yakavimbika mhedzisiro. Iwe unofanirwa kuita izvi zvese zvisati zvaitika uye panguva yekuyerwa kwehuwandu. (2)
• Gara uchienzanisa yako analog multimeter usati waita chero yakakomba yekuyedza kana kugadzirisa dambudziko. Ini ndinokurudzira zvikuru svondo rekuenzanisa kana iwe ukashandisa mudziyo wako zuva nezuva.
• Kana iwe ukawana shanduko huru muzviyero, inguva yekutsiva mabhatiri.
• Kana iwe uine chokwadi cheiyo chaiyo kukosha kweiyo yakayerwa kukosha mu volts, nguva dzose sarudza iyo yepamusoro siyana.
