Momwe mungayesere zamakono ndi multimeter (phunziro la magawo awiri)

Pogwira ntchito yamagetsi, mungafunike kuyang'ana kuchuluka kwa magetsi kapena magetsi omwe akuyenda mozungulira. Muyeneranso kuyeza amperage kuti muwone ngati pali chilichonse chikukoka mphamvu kuposa momwe ziyenera kukhalira.

Kuyeza pakali pano kungakhale kothandiza poyesa kudziwa ngati gawo lagalimoto yanu likukhetsa batri yanu.

Mwamwayi, kuyeza kwanthawi yayitali sikovuta ngati mukudziwa mayeso oyambira a multimeter ndikusamala pazinthu zamagetsi.

Ndiroleni ndikuthandizeni kuphunzira kuyeza ma amps ndi ma multimeter. 

Kusamala

Muyenera kusamala ngati mukugwiritsa ntchito multimeter yosavuta kapena multimeter ya digito. Mukayesa magetsi, muyeso uliwonse womwe ukugwiritsidwa ntchito pano ukuwonetsa zoopsa zomwe ziyenera kuganiziridwa. Musanagwiritse ntchito zida zilizonse zoyezera magetsi, anthu aziwerenga buku la ogwiritsa ntchito nthawi zonse. Ndikofunikira kuphunzira za njira zoyenera zogwirira ntchito, zodzitetezera komanso zoletsa. (1)

Valani magolovesi olemera, pewani kugwira ntchito pafupi ndi madzi kapena zitsulo, ndipo musagwire mawaya opanda kanthu ndi manja. Ndikwabwinonso kukhala ndi munthu pafupi. Munthu amene angakuthandizeni kapena kuyimba foni kuti akuthandizeni mukagwidwa ndi magetsi.

Kupanga kwa Multimeter

Nambala 1. Dziwani kuti ndi ma amp-volts angati a batri yanu kapena chowotcha chozungulira chomwe chingagwire pa nameplate.

Onetsetsani kuti ma multimeter anu akugwirizana ndi kuchuluka kwa ma amps omwe akuyenda mozungulira musanayambe kulumikiza nawo. Imawonetsa kuchuluka kwamphamvu kwamagetsi ambiri, monga momwe zikuwonekera pa dzina. Kumbuyo kwa chida kapena mu bukhu la ogwiritsa ntchito, mutha kupeza kuchuluka kwa mawaya a multimeter. Mutha kuwonanso momwe sikelo ikukwera. Osayesa kuyeza mafunde opitilira muyeso wa sikelo. 

#2 Gwiritsani ntchito mapulagi-in-clamps ngati ma multimeter anu akuwongolera siwokwanira kuzungulira. 

Ikani mawaya mu multimeter ndikugwirizanitsa ndi dera. Chitani izi mofanana ndi ma clamp multimeter. Mangirirani chingwecho mozungulira waya wamoyo kapena wotentha. Nthawi zambiri imakhala yakuda, yofiira, yabuluu, kapena mtundu wina osati woyera kapena wobiriwira. Mosiyana ndi kugwiritsa ntchito multimeter, ma clamps sadzakhala gawo la dera.

Nambala 3. Lowetsani kuyesa kwakuda kumatsogolera padoko la multimeter's COM.

Ngakhale mukamagwiritsa ntchito jig, multimeter yanu iyenera kukhala ndi zowongolera zofiira ndi zakuda. Chofufuzacho chidzakhalanso ndi nsonga kumbali imodzi yolumikizira chidacho. Wotsogolera wakuda woyesa, womwe ndi waya wopanda pake, uyenera kulumikizidwa nthawi zonse mu jack COM. "COM" imayimira "wamba", ndipo ngati doko silinalembedwe, mutha kupeza chizindikiro choyipa m'malo mwake.

Ngati mawaya anu ali ndi mapini, muyenera kuwasunga m'malo poyezera mphamvu. Mutha kumasula manja anu powalumikiza ku unyolo ngati ali ndi tatifupi. Komabe, mitundu yonse iwiri ya ma probe imalumikizidwa ndi mita mwanjira yomweyo.

No. 4. Lowetsani kafukufuku wofiira mu socket "A".

Mutha kuwona malo awiri okhala ndi zilembo "A", imodzi yolembedwa "A" kapena "10A" ndi ina yolembedwa "mA". mA outlet imayesa mamilimita mpaka pafupifupi 10 mA. Ngati simukudziwa kuti mungagwiritse ntchito chiyani, sankhani "A" kapena "10A" kuti mupewe kulemetsa mita.

No. 5. Pa mita, mungasankhe AC kapena DC voltage.

Ngati mita yanu ndi yoyesera mabwalo a AC kapena DC okha, muyenera kusankha yomwe mukuyesera kuyesa. Ngati simukutsimikiza, yang'ananinso chizindikiro pamagetsi. Izi ziyenera kutchulidwa pafupi ndi voltage. Direct current (DC) imagwiritsidwa ntchito m'magalimoto ndi zida zamagetsi zamagetsi, pomwe ma alternating current (AC) amagwiritsidwa ntchito kwambiri pazida zam'nyumba ndi ma mota amagetsi.

No. 6. Pakuyezera, ikani sikelo ku mlingo wapamwamba wa ampere-volt.

Mukawerengera mafunde apamwamba kwambiri kuti muyese, pezani lever pa mita yanu. Izungulirani mokwera pang'ono kuposa nambala iyi. Ngati mukufuna kusamala, tembenuzirani kuyimba kwapamwamba. Koma ngati mphamvu yoyezerayo ndiyotsika kwambiri, simungathe kuwerenga. Izi zikachitika, muyenera kuchepetsa sikelo ndikuyambiranso ntchitoyo.

Momwe mungayesere volt-ampere ndi multimeter

Nambala 1. Zimitsani mphamvu yamagetsi.

Ngati dera lanu limayendetsedwa ndi batire, chotsani chingwe choyipa kuchokera ku batri. Ngati mukufuna kuzimitsa magetsi ndi chosinthira, zimitsani chosinthira, kenako kulumikiza mzere wosiyana. Osalumikiza mita ku dera pamene magetsi ali.

No. 2. Lumikizani waya wofiira kuchokera kumagetsi.

Kuti muyeze zomwe zikuyenda mozungulira, lumikizani ma multimeter kuti mumalize maphunzirowo. Kuti muyambe, zimitsani mphamvu yozungulira, kenako kulumikiza waya wabwino (wofiira) kuchokera kugwero lamagetsi. (2)

Mungafunike kudula waya ndi zodula mawaya kuti muthyole unyolo. Onani ngati pali pulagi pamphambano ya waya wamagetsi ndi waya wopita ku chida choyesedwa. Ingochotsani chivundikirocho ndikumasula zingwe mozungulirana.  

Nambala 3. Mangani nsonga za mawaya ngati kuli kofunikira.

Manga mawaya pang'ono mozungulira mapini a multimeter, kapena siyani mawaya okwanira owonekera kuti mapini a alligator atseke bwino. Ngati waya watsekedwa kwathunthu, tengani zodula mawaya pafupifupi inchi imodzi (1 cm) kuchokera kumapeto. Finyanini mokwanira kuti mudutse zotsekera mphira. Kenako kukoka mawaya mwachangu kwa inu kuti muchotse zotsekera.

No. 4. Manga chowongolera choyesa cha multimeter ndi waya wabwino.

Manga malekezero opanda kanthu a waya wofiira ndi tepi yolowera kutali ndi gwero la magetsi. Gwirizanitsani zidutswa za alligator ku waya kapena kukulunga nsonga ya kafukufuku wa multimeter mozungulira. Mulimonsemo, kuti mupeze zotsatira zolondola, onetsetsani kuti waya ndi wotetezeka.

No. 5. Limbikitsani dera pogwirizanitsa kafukufuku wakuda wa multimeter ku waya wotsiriza.

Pezani waya wabwino wochokera ku chipangizo chamagetsi chomwe chikuyesedwa ndikuchilumikiza kunsonga yakuda ya multimeter. Mukadula zingwe kuchokera pa batire yoyendetsedwa ndi batire, ipezanso mphamvu zake. Yatsani magetsi ngati munazimitsa ndi fuse kapena switch.

Nambala 6. Pamene mukuwerenga mita, siyani zipangizozo kwa mphindi imodzi.

Mukayika mita, muyenera kuwona nthawi yomweyo mtengo womwe ukuwonetsedwa. Ichi ndi muyeso wapano kapena wapano padera lanu. Kuti muyezedwe molondola kwambiri, sungani zidazo mozungulira kwa mphindi imodzi kuti muwonetsetse kuti zida zili pompopompo.

Mutha kuyang'ana mayeso ena a multimeter omwe talemba pansipa;

• Momwe mungagwiritsire ntchito multimeter kuti muwone mphamvu ya mawaya amoyo
• Momwe mungakhazikitsire amplifier ndi multimeter
• Momwe mungayang'anire waya ndi multimeter
