Maitiro ekutarisa kubuda kweamplifier ine multimeter
Zviri mukati
Mota amplifiers anobatsira kuvandudza ruzivo rwako rwekuteerera, kunyanya kana zvasvika kumumhanzi kubva kumota yako kana imba stereo system.
Kuburikidza nekushandiswa kwema transistors, ivo vanokwidziridza mutsindo kubva kune ekuisa masosi, saka iwo anonyatso dhindwa pavatauri vakuru.
Ehe, kana paine dambudziko neamplifier, mota yekuteerera system inotambura.
Imwe nzira yekuita ongororo ndeyekutarisa kana amplifier iri kuburitsa zvakakodzera, asi havasi vese vanoziva maitiro ekuita izvi.
Mugwaro iri, iwe uchadzidza maitiro ekuyedza kubuda kweamplifier ine multimeter.
Ngatitangei.
Kutarisa Zvinyorwa Zvekupinda
Nhanho yekutanga yaunoda kutora ndeyekutarisa kuti chiratidzo chakakodzera kana simba riri kuuya kubva kune yekuisa masosi.
Iyo amplifier inofambiswa newaya mbiri dzinobva kune dzimwe nzvimbo dzemotokari.
Izvi zvinosanganisira waya imwe inouya kubva ku12V bhatiri uye imwe waya kubva pasi pechasi yemotokari.
Kana huwandu hwakakodzera hwesimba husiri kupihwa, iwe unotarisira kuti amplifier iri kuita zvisina kunaka.
- Tsvaga yako amplifier uye yekuisa simba sosi
Iyo amplifier inowanzo kuwanikwa pasi pe dashboard, mutrunk yemotokari, kana kuseri kwechimwe chezvigaro zvemotokari.
Iwe zvakare unozoona kuti ndeipi tambo iri kudyisa amplifier. Unogona kunongedzera kubhuku remuridzi remota yako kana amplifier.
- Batidza moto wemoto
Iwe unoda kuti waya ive inopisa kuitira kuti uwane kuverenga kubva mairi. Batidza moto wemoto kuti utange usina kubatidza injini. Zvakwana.
- Tora kuverenga kubva kune waya dzekupinza
Seta iyo multimeter kuDC voltage uye isa bvunzo inotungamira pane dzakaratidzwa waya dzekuisa.
Isa dzvuku (positive) bvunzo lead pawaya yakanaka uye isa multimeter yakasviba (negative) bvunzo lead pawaya yepasi.
Simba rakanaka rinokupa iwe kuverenga pakati pe11V ne14V.
Volume test
Kumwe kuyedza kwaunogona kuita kunogona kukupa rumwe ruzivo nezve PSU yako.
Nepo ma multimeter anotungamira achiri akabatana newaya dzekupinza, simudza vhoriyamu mumotokari.
Kana iwe ukasawana chero kuwedzera mukuverenga voltage, saka pane dambudziko neiyo yekuisa sosi uye uri kuita imwe kubvunza nezvazvo.
Fuse bvunzo
Rimwe dambudziko rine yakashata amplifier simba rekupa rinogona kuve rakakanganisika amplifier fuse.
Kuti uedze izvi, iwe unongowana yako amplifier's power fuse, isa multimeter yako kuti irambe, uye isa bvunzo inotungamira kumativi ese ari maviri efuse.
Kana iyo amplifier ichiratidza kukosha kwakashata, fuse yakaipa uye inoda kutsiviwa.
Iwe unogona zvakare kutarisa gwara redu rekutarisa fuse pasina multimeter.
Mukuwedzera, mamwe amplifiers anewo yakachengeteka mode.
Kana yako yakashongedzerwa nebasa iri uye ichipinda mune yakachengeteka modhi paunoibatidza, ipapo magetsi emagetsi akanganisa.
Imwe nyaya iyo yakachengeteka modhi inogona kuvhurwa ndeye kana iyo amplifier yakaiswa pairi kana kubata inofambisa nzvimbo.
Maitiro ekutarisa kubuda kweamplifier ine multimeter
Isa CD pa50 Hz kana 1 kHz pa0 dB mubhokisi rekubva, isa multimeter kuAC voltage pakati pe10 ne100 VAC, uye isa inotungamira yemultimeter pane inobuda terminals yeamplifier. Iyo yakanaka amplifier inotarisirwa kupa voltage kuverenga inoenderana neyakakurudzirwa kubuda simba zvakakwana.
Tichatsanangura mberi.
- Dzima vatauri
Nhanho yekutanga ndeyekubvisa waya dzemutauri kubva kune amplifier inobuda materminal.
Aya ndiwo materminal aunoda kuyedza paari, saka kubvisa waya dzemutauri kwakakosha.
Pamusoro pezvo, iwe zvakare unoda kudzima kana kudzima chero emagetsi crossovers akabatana kune amplifier's inobuda terminals.
Izvi zvinoitirwa kuti pasave nekuvhiringwa nebvunzo.
- Isa iyo multimeter kune AC voltage
Kunyangwe iyo mota amplifier ichifambiswa neDC voltage, iyo amplifier inoshandura yakaderera ikozvino / yakaderera voltage kuita yakakwira yekubuda chiratidzo kuverenga.
Iri kuchinjana, saka unoseta multimeter yako kuAC voltage kuti uedze zvinobuda. AC voltage inowanzonzi "VAC" pane multimeter.
Iwe unogona zvakare kuiisa muyegumi-10VAC renji kuti uve nechokwadi chekuti multimeter iri kupa mhedzisiro chaiyo.
- Isa iyo multimeter inotungamira pane inobuda terminals yeamplifier
Mushure mekunge nhanho mbiri dzapfuura dzapera, iwe unongoisa inotungamira yemultimeter pane inobuda terminals yeamplifier.
Aya ndiwo mabudiro awakabvisa waya dzesipika.
Isa iyo yakanaka bvunzo inotungamira pane yakanaka inobuda terminal yeamplifier uye iyo isina kunaka bvunzo inotungamira pane isina kunaka inobuda terminal.
Kana iyo amplifier ikavharirwa kana kushanda mumono, ingobatanidza iyo yakanaka uye yakaipa inotungamira kune shunt inobuda materminal.
- Isa bvunzo frequency
Nzira iri nyore yekushandisa frequency yekuyedza masaini masaini ndeyekuridza bvunzo tune.
Iwe unoisa CD kana kungoridza tune kubva kune chero ipi zvayo yekuisa yaunayo.
Nekudaro, chinonyanya kukosha ndechekuti rwiyo urwu runofanira kurira panguva chaiyo yevatauri vauri kushandisa.
Kune ma subwoofers, iwe unoda kuridza rwiyo rwe50 Hz pa "0 dB", uye yepakati kana yakakwirira frequency amplifiers, unofanirwa kuridza rwiyo rwe1 kHz pa "0 dB".
Neimwe nzira, iwe unogona zvakare kushandisa chiratidzo jenareta.
Iwe unobvisa waya dzese dzekupinza uye dzekuburitsa kubva kune amplifier, batanidza jenareta rechiratidzo kune materminal ekuisa neRCA tambo, uye isa iyo multimeter inotungamira pane inobuda terminals yeamplifier.
Nejenareta yechiratidzo yakabatidzwa, unomhanyisa frequency kusvika padanho rakakodzera kune vatauri vako.
Zvekare, iwe unoda 50Hz ye subwoofers, kana 1kHz ye midrange uye treble amplifiers.
- Reta zvabuda
Apa ndipo pazvinooma.
Mushure mekushandisa yako bvunzo frequency uye kurekodha yako multimeter kuverenga, iwe uchafanirwa kuita mamwe maverengero.
Amplifiers anotarisirwa kuburitsa anokurudzirwa simba rekubuda mumhando ye50 kusvika 200 watts, uye izvi zvinowanzotaurwa mugwaro kana pane amplifier kesi.
Iwe unoshandura voltage yako kuita watts uye kuenzanisa.
Formula yekuverenga watts
E²/R uko E ari voltage uye R iri kuramba.
Iwe unogona kuwana yakakurudzirwa kuramba pane iyo kesi kana mune yako amplifier's manual.
Semuenzaniso, tarisa mamiriro ezvinhu apo iwe uri kushandisa 8 ohm subwoofers uye iwe unowana kuverenga kwevheji ye 26. Mune subwoofer, 8 ohms inofanana mutoro we 4 ohm resistors pane amplifier.
Watt \u26d (26 × 4) / 169, \uXNUMXd XNUMX watts.
Kana iyo yakayerwa simba isingaenderane neyakakurudzirwa kuburitsa simba reamplifier, ipapo amplifier haina kukwana uye inofanirwa kuongororwa kana kutsiviwa.
mhedziso
Kutarisa kuburitsa kweamplifier ine multimeter iri nyore. Iwe unoyera iyo AC voltage inogadzirwa panzvimbo yayo yekubuda uye woienzanisa neyakakurudzirwa wattage yeamplifier.
Imwe nzira yekugadzirisa kusabuda zvakanaka kweamplifier ndeyekugadzirisa zvayakawana, uye iwe unogona kutarisa chinyorwa chedu nezve tuning uye yekuyedza amplifier inowanikwa ine multimeter.
Inowanzobvunzwa Mibvunzo
Nzira yekutarisa amplifier yekushanda?
Cheki chekukurumidza ndechekuona kuti ruzha rwemhando yakanaka. Zvakare, kana iyo yekupinza simba kana inonzwika masosi yakaipa, iwe uchave nematambudziko kunyangwe iyo amplifier iri kushanda zvakakwana. Edzai zvinyorwa izvi.
Chii chinobuda voltage yeaudio amplifier?
Iyo inotarisirwa kubuda voltage yeaudio amplifier iri pakati pe14V kusvika 28V ye8 ohm amplifier. Nekudaro, izvi zvinoenderana nesimba rekuisa uye mhando yeamplifier inoshandiswa.
Nzira yekuziva sei kuti amplifier yakapiswa kunze?
Zviratidzo zveamplifier yakatsva zvinosanganisira kurira kusinganzwisisike kana manzwi akamonyaniswa kubva kune masipika, uye masipika haabudise ruzha zvachose, kunyange kana gudzanzwi rakabatidzwa.
Unoverenga sei maamps ane clamp mita?
Isa tambo pakati peprobe sleeve yezvino clamp, isa iyo yekupokana uye tarisa kuverenga. Ita shuwa kuti waya inosvika 2.5 cm kure nesleeve ye sensor uye kuyera imwe panguva.
Nzira yekuyedza DC amplifiers ine multimeter?
Isa iyo nhema inotungamira mu "COM" chiteshi uye tsvuku inotungamira mu "Amp" chiteshi, inowanzonzi "10A", zvichienderana nemultimeter. Wobva waisa dial kuti uverenge DC amps.
