Indlela hlola Amps multimeter? imfundo

Multimeter ngokuthi lolithulusi kulinganiswa voltage, zamanje, ukumelana, wenziwa "embili" izintambo. Okungukuthi, le divayisi funa okwanele. Futhi, njengoba umkhuba zibonisa, uyawuthanda ethandwa okwanele hhayi kuphela umkhakha kodwa futhi ekuphileni kwansuku zonke.

Kodwa ngaphambi kokuba uqale, isilinganiso, kufanele kuphawulwe ukuthi multimeter - kudivayisi ngempela ayinangozi. Uma sisetshenziswa ngendlela engafanele, hhayi kuphela kalula ukukuvimbela, kodwa futhi udale umonakalo omkhulu empilweni yakho. Lokhu kuyiqiniso ikakhulukazi ezimweni lapho kudingeka afeze izilinganiso at voltage okusezingeni eliphezulu noma amperage okusezingeni eliphezulu. Awukwazi nje ngokushesha ashise imitha, kodwa futhi ukuthola sina umuntu abanjwe ugesi.

Yingakho, ngaphambi kokuba uqale ukusebenzisa imitha, kumele wena eziqeqeshelwe segezi nokusebenza ongaphakeme kwamanje, njengezici ibhethri. Kufanele indiva umyalelo kudivayisi.

izinhlobonhlobo multimeters

Ukuze uqale, kufanele wazi ukuthi multimeters kukhona digital futhi analog (umcibisholo, ngisho phakathi Electricians, baziwa ngokuthi "tseshka"). Electricians Okwesibili zaziwa isikhathi eside, kodwa ukuzisebenzisa ngaphandle kolwazi ekhethekile futhi umkhuba kunzima.

• kumele bakwazi ukuqonda isikali zedivayisi, lapho ukushelela multimeter ezimbalwa;
• ithuluzi kufanele ubanjwe usesimweni esinjalo, uma akukho umcibisholo kuso 'ukuhamba' kulesi silinganiso.

Yingakho, uma kukhona kungenzeka esinjalo, kungcono ukusebenzisa multimeter digital. Sizophinde sixoxe ngezibonelo usebenzisa nje idivayisi digital njengoba uzithanda wena ufunde ukusebenza nzima nge multimeters analog.

Izinhlobonhlobo digital multimeters ngokwanele, kodwa isebenza kanjani iyafana komunye nomunye - umehluko kuphela isibalo kudivayisi imisebenzi. Ngenxa yalokho, kusukela ukusebenza multimeter futhi intengo lincike, ngakho ngaphambi kokukuthenga ke, nquma ukuthi iyini okudingayo.

Imitha liqukethe:

• zedivayisi ngokwayo;
• iphenya ezimbili (ezimnyama);
• amandla umthombo (ibhethri "Umqhele" 9B).

Ngakho, iziphi izici ukusetshenziswa ithuluzi wokulinganisa nendlela ukuhlola Amps multimeter?

imfundo

Ukuze ulinganise wamanje yesifunda, kuba ngokulandelana kudingeke ukuba uxhume kudivayisi nalokho. Ngesikhathi esifanayo kwi multimeter kuyadingeka ukuba kuphenywe elibomvu phakathi izisekelo on insimbi ne ma alebuliwe, futhi omnyama - e com. uxhumano yomkhiqizo kusho ukuthi kumele uphule iketango Uphenyo ngamunye kuxhunywe wire ezahlukene, t. E. kudivayisi Kumele uxhumeke phakathi imithombo ezimbili ngamandla. Kodwa njengoba ukukala amandla samanje, futhi amandla ukukwenza awulona imithombo kungenzeka, kumele uvule ku uchungechunge ezinye idivayisi, ezifana ezivamile ukukhanya Isibani, ngikubeka wesifunda ngokushesha ngemva umthombo wamandla.

Uma kulinganiswa amandla AC, idivayisi isethelwe seqiwe we-AC (uphawu A ~ - uqaphele ukuthi okufana kakhulu DC isithonjana (A), ngakho-ke qaphela). Futhi kuphela emva kwalokho ungaqala izilinganiso.

Ngaphambi hlola ampere multimeter, qiniseka ukuthi amandla lamanje elinganisiwe akuyona liphezulu kakhulu, isb. A., izilinganiso okunjalo kungase kungabi okuphephile ngenxa encane Ingxenye evundlile izintambo uphenyo. Lesi sakamuva awukwazi ukumelana imithwalo eliphezulu. Ochwepheshe batusa ukuba ukuqhuba izilinganiso ngesikhathi Inani lamanje 10 A clip-on.

Hlola multimeter ibhethri

Ihlola kufanele sigcwaliswe kuphela ngaphansi komthwalo. Hlola amperes eziningi kanjani ibhethri multimeter kuphela usebenzisa umthamo webhethri yangaphakathi akunakwenzeka ngoba ukubaluleka kwalo ongaphakeme - okuholela izibalo musa ziveza izibalo kweqiniso.

Tester kungaba ukukala hhayi kuphela yokusebenza yamanje, kodwa futhi ukuvuza samanje ibhethri. Ngaphambi hlola multimeter wakho njengoba amperes ka ukuvuza wamanje, kumele ukhumbule ukuthi kungase kufike ku amperes eziningana. Ngakho-ke wagqoka uhla yokukala ithuluzi kufanele kube ngendlela efanele, kungcono 10 A.

Ngo umkhuba ngaphambi kokubhala isivivinyo ebhethrini Amps multimeter iziphakamisile nge terminals battery ibhethri ikhebula omuhle futhi ukumfaka kudivayisi nomphumela igebe wokulinganisa. Khona-ke udinga:

• ukhethe imodi phezu multimeter ukukala zamanje;
• silungise "ingwenya" wire futhi yanjalo ukudonsa fuses, okuyinto banesibopho module e-elekthronikhi emotweni.

Nge umkhuba othile, uzoba hhayi kuphela ukwazi ukuthi ukuhlola Amps multimeter, kodwa futhi kalula ukuthola imbangela ukuvuza, ngaphandle asebenzise esikhungweni sesevisi.

Ihlola ishaja

Ngaphambi kokuba siphendule lo mbuzo: "Indlela ukuhlola Amps multimeter ku ishaja," kumelwe wazi ukuthi ungakwazi ukukala, isimiso, iyiphi ukushaja. Kungaba kusukela kufoni yakho noma ithebulethi, ishaja semoto ibhethri, nokunye. D.

Ucingo Ishaja

izilinganiso anjalo ngokuvamile iyadingeka uma kubalulekile ukukhomba imbangela imemori iphutha. Kufanele kuqashelwe ukuthi amandla samanje amashaja yocingo, amaphilisi kanye nokunye. E. kancane ezahlukene futhi ngokuvamile wabonisa kwilebula ishaja noma wokugubha. Kodwa uma kungekho ilebula enjalo, kungakhathaliseki ukuthi ibangelwa yini, khona-ke ungakwazi ukuhlola lesi multimeter sibalo.

Isimiso sokukala zamanje ishaja angahluka kuphela yokuthi kunzima ukuxhuma kubo iphenya multimeter ngenxa yobukhulu encane oxhumana nabo ku-isixhumi. Kuze kube yimanje, kumele oxhumana ifakwe ngokucophelela abavamile steel inaliti yokuthunga baye kubo ukuxhuma iphenya multimeter. Uma bobabili ungaphenduki, ke Sokuzivikela kuphela emcimbini wokuvulwa ukushaja izindlu ukuxhuma iphenya ngqo terminals inkumbulo endaweni lapho imikhawulo kuthiwa soldered intambo kagesi.

Ishaja ye-emotweni ibhethri

Ngaphambi sikhuluma kanjani ukuhlola Amps ku ishaja multimeter semoto ibhethri, odinga ukukwazi, kwenzani na.

Inani kahle lamanje ukukhokhiswa imemori 10% amandla ibhethri imoto. Inani elikhulu ivumela ngokushesha ashona ibhethri, kodwa ngeke esilimaza ibhethri uqobo, futhi kakhulu ukunciphisa isikhathi yokusetshenziswa kwawo.

Lapho uthenga inkumbulo ezifana ukugcina zonke nemingcele zibhaliwe ishaja. Kodwa icala elinjalo elibekwe ingane, ngolwazi sakugcina kungenziwa ngokuzimela. Kulokhu ungase beze multimeter Ukugunda. Futhi, lokhu imitha kuyasiza uma imemori ehluleka.

Kufanele ukuthi uma yokulinganisa amperage kwanoma iyiphi amashaja yesifunda kufanele kubandakanye noma yiziphi umthwalo (isib ezejwayelekile light isibani). Futhi, ungakhohlwa ukuthi inkumbulo ngokuvamile inikeza zamanje njalo, ngakho esibayeni imitha kumele obala isikhundla lesifanele (A).

Hlola amandla supply

Indlela hlola Amps multimeter phezu kwamandla? Lokhu kwenziwa ngokuthi umthwalo eqine edingekayo ukuze ukwazi ukusebenzisa. Isimiso ayikanye ihluke kakhulu kwethi kokuhlola kweminye imithombo. Kuyinto kudingekile kuphela ukwazi ukuthi PSU sinesikhundla kunalokho enkulu, ngakho izilinganiso kufanele kwenziwe ngokushesha, ngaphandle Ukushisa izintambo multimeter iphenya.

Njengoba singabona, imitha kungaba wusizo kakhulu ekuphileni kwansuku zonke futhi ziphoqa ezindaweni ezahlukene ngokuphelele, ngakho ukuthola ulwazi sakugcina kakhulu ukusetshenziswa kwayo ngeke engadingekile.
