Chii digitaalinen multimeters

Another chikoro kosi mukuru mu wefizikisi chikazozikamwa, kuti zvemagetsi wedunhu iri dzinoratidzwa anoverengeka parameters. Pakati pavo, ivo voltage mutengo, hunonziwo dzingangoitika kukosha uye mhando kuitika ruchiyerera napakati kondakita, simba ufungisise mutoro kubva pomumbure, ari kurwisa ukoshi (mu Ohms) nevamwe. Kuyera nomumwe izvi unyanzvi mano zvakasikwa. Nokuti ichi kuitika ammeters, voltage -. Voltmeters, ohmmeters kuti nemishonga, etc. Zvisinei, chii kana pane chikonzero kuyera vanopfuura mumwe parameter, asi akawanda? Pfeka zvose huripo Namano ine? Muchiitiko chino, kwete kutaura kufamba uye nyore. yezvisikwa mhinduro zvakasikwa kugadzirisa dambudziko iri: mano vakuru tichibatanidza akawanda vamwe. Somuenzaniso, ufambe wokutanga nenzvimbo chaiyo chinja, unogona uyere voltage, ari kusashanda womukati pfungwa yechipiri, iyo anobvumira kuziva kurwisa. Yakakodzera! mano zvakadai vanozivikanwa se multimeters. Ndicho "Multi" - yakawanda, zvakanaka, "metres" - chiyero. Wechipiri rokuremekedza, izvo zvisiri chaizvo kwakarurama, - testers. Modern digitaalinen multimeters kubvumira kuti kuyera munhu muzvizhinji kuti parameters kubva nyore kudzivisa redunhu mugove kuna ambient tembiricha.

okunatsiridza

Pasinei siyana mano aya, vari rakakamurwa huru mhando mbiri: analoginen uye digitaalinen multimeters. For vanoshandisa vakawanda Zvisinei yamunenge Chechipiri, kunyange zvazvo pakutanga ane zvakawanda zvakanaka,, zvakananga.

The kudzidza kukuru uye museve

Analog womuenzaniso rinenge kubva okuwana, sezvo kwokudiwa pavo muduku, zvichienzaniswa kune dzimwe (Digital Multimeter DT zvino kusimba nevakawanda). Zvisinei, nepamusika achiri zvinogoneka kusangana itsva, zvinogadzirisa yakafanana, saka kumboongorora pavo. Analog mano zviri nyore chaizvo kusiyanisa vamwe pamusoro muviri ndiwo chinja Ratchet kuti pakanzi kuyera rudzi, uyewo kumbonyanya guru pakapuranga aine chikero hwaakange kupesana chiratidzo (akafanana mutsetse). Apo unobva vachiongorora kuti redunhu kuitika rikaitika yomukati Coils, minda rinobva kunotangira uye kudyidzana kwavo uchivirisa zvichiratidza museve vakatsauka pane imwe akachinjikana. It chete inoramba kuti mutengo kuti weboka uye kudzidza kukosha chakayerwa parameter. Digital multimeters munhau iyi zvinodiwa kubva kukanganisa risingabatanidzwi shanduro grading pamwero pazasi hwakaratidza ratchet muganhu.

Display nhamba

Digital Multimeters tarisa rinenge kufanana analoginen, asi kuti Pointer chinogumbura kuchatsiviwa chitsidzo chidzitiro, izvo zvinoratidza nokuyerwa zvabuda. Kuchinja Internal Chokwadi, zvakawanda zvinokosha. On akadhindwa redunhu bhodhi wakaiswa Chip kuti anoita kubudiswa wakakwana huri kuuya chiratidzo kubva vachiongorora. Kazhinji, vanoverengeka mamwe masangano anoshandiswa - resistors, capacitors uye Coils. Pakati pachena zviri izvi zvisarudzo, zvinokosha kuziva zvishoma kukanganisa yakayerwa - soro zvakarurama kirasi, tinoberekwa kunyange bhajeti yokutevedzera Somuenzaniso, akadai 838 digitaalinen multimeter.

Achiratidza

Nokuti munhu neapo panodikanwa kuti kuyera zvimwe parameters kwemutariri pamusha kana Somuenzaniso, mune motokari zvemagetsi ezvinhu, rweruzhinji digitaalinen tester ndiyo yakanakisisa sarudzo. Zvakatikwanira kunzwisisa mitemo vanoshandisa ratchet uye kunzwisisa nheyo kusarudza nokuyerwa siyana.
