Ibhethri - indlela ukuhlola multimeter? car amabhethri

Ibattery kudinga handling ngokucophelela kanye nokusebenza isiyonke mkhosi okuqinile imithetho. Kufanele siqonde ukuthi isakhi esibalulekile le electrochemical isakhiwo imoto, lapho kuncike ukusebenza izingxenye eziningi nemikhulu. Okubaluleke kakhulu ngokuya sevisi isimo ukuhlaziywa ibhethri. Ukuze wenze lokhu, sebenzisa ithuluzi ekhethekile, ikakhulukazi ukuhlola uhlobo lapho ibhethri isebenza. Indlela hlola multimeter, iyunithi - udaba emaphakathi kwalesi sihloko. Naphezu kalula okusobala inqubo, kukhona umehluko wemisindo nemiqondo yamagama amaningi ukuthi kumelwe acabangele umakhenikha futhi imfundamakhwela ngaphezulu umshayeli.

ukuhlolwa kwangaphandle ibhethri

Ngaphambi umcimbi kufanele ahlaziye isimo esihlelekile ibhethri. Ngokuvamile, ukuthi iziphetho ezibaluleke mayelana idivayisi ezisebenza ezingaba kungenziwa kulesigaba Lesiphakeme. Isheke wokuqala ezibukwayo kumelwe ubonise, akusiyo zibe futhi ongakulungele yokutakula iyunithi. Lokhu kungase kubonise sina umzimba wenyama ukusonteka seal ukwehluleka. Kulo mBhalo, ukuhlukanisa ibhethri ngokushesha. "Indlela ukuhlola multimeter?" - lo mbuzo uqhubeke esimweni esobala yokulimala zangaphandle atholakele. Nokho, lokhu akusho ukuthi singakwazi ngokushesha uqale ukusebenza test. Umzimba futhi ikakhulukazi izingxenye afingqe oxhumana kumelwe esimweni ukuhlanzwa. Kufanele siqiniseke ukuthi ezimweni ezithile sebhetri, isimiso, uvunyelwe ukuhlola yasendlini abahloli izimo.

Ihlola iyunithi ezisebenza

Kudivayisi uhumusha imodi asebenzayo, amagugu ke kungenziwa isethwe uhla lapho ibhethri wahlulelwa esidingekile. Indlela hlola ibhethri multimeter nge injini ukugijima? Ixhuma amadivayisi wenziwa ngendlela evamile, kanye polarity lesifanele. Kulokhu-ke izenzo classical ukumisa uxhumano ezikhumulweni. Njengoba for ukufundwa, kubhekwa amazinga evamile yamandla aphindeke kabili ye kusuka 13.5 kuya 14 V. Akukhona ukuthi okungaphezu kwalokho kubonisa ukuwohloka kwezindinganiso supply amandla, kodwa ngeziphambeko ezithile emsebenzini zenzeke.

Uma voltage idlula 14.2 V ke kungaba ibhetri iphansi. Ngakho ekuqaleni ke ngeke engadingekile ukubuza mayelana nendlela ukhokhiswe ngesikhathi sokuhlolwa. Mhlawumbe ukwehla yayo kwakubangelwa ebusuku nesithwathwa lapho electronics kudle ngokuzenzakalela amandla for bafudumale. On umbuzo kanjani ukuhlola icala battery, njengoba izingxenye ezibalulekile ukulungiswa nezinye zendawo Ihluzo Elingafaki Ukuqoka. It is ekuqaleni ukukhubaza bonke abasebenzisi, bese uqale ukulinganisa.

Izici test ibhethri esimweni sokungenzi lutho

Mechanics Ukulinganiswa kokusebenza kulesi simo oluvumelana nesibonelo ngenhla echazwe. Ukuze uthole imiphumela, kuzomele ulinde imizuzu engu-15 - incike version of the imitha. By the way, umbuzo kanjani ukuhlola ibhethri ekusebenzeni, ngokuvamile kuhilela izinqubo abacula format ezinjalo. Ngaphezu kwalokho, ukuba khona nje umsebenzi electrochemical unit namanje akakhulumi mayelana nokwenzeka nokusebenza kwawo okuvamile.

Izinkomba voltage ngaphansana 12 abonisa avame ukuthi iphakethe liphele ngokuphelele futhi asifanele ukusetshenziswa - okungenani okwamanje. I ububanzi bamanani evamile injini isezingeni kokungenzi lutho ephasishi 12,5-13,0 V Lezi izinkomba efanayo uyofunda indlela ngecala lokuvukela auto amabhethri ngesikhathi nesilinganiso. Le nqubo akukuniki swe kahle lesi silinganiso, kodwa ngokuvamile kuyiqiniso enephutha encane. Ngokwesibonelo, voltage ka 12.9 kungase kubonise ukuthi ibhethri is icala by 90% kanye ezingeni kubonisa khona 12.5 isigamu kwenkokhelo.

Hlola i-plug ukulayisha ibhethri

Ukuhlola ukukhokha futhi Kunconywa ukuba asebenzise ngemfoloko umthwalo, okuyinto ngokuyisisekelo kuyinto voltmeter. Uxhumano senziwa ngendlela efanayo njengoba kwaba njalo endabeni nge multimeter kuya polarity lesifanele. Kodwa kukhona futhi isici esibalulekile saleso isilinganiso esinjalo. Impendulo yombuzo kanjani ukuhlola umhloli ibhethri, voltmeter, kudinga ukuhambisana okusheshayo yesivalo ngesivinini, lapho Siyonikwa ukuba umthwalo. Ngokushesha ngemva uxhumano kufanele uqale ngokubala amasekhondi angu-5, ngemva kwalokho umthwalo imisiwe futhi asuswe ukufundwa yomculo. Uma umhloli kubonisa volts 10 noma ngaphezulu, khona-ke icala likhona futhi ibhethri kungenziwa eziqhutshwa. Kumele kukhunjulwe ukuthi ekuphambukeni umthwalo e ukuxhumana yayo nge ibhethri ukuziqalela iyafana isigaba injini. Nokho, ngokuvamile, ukuze afeze izivivinyo ezifana kuyingozi ibhethri.

Hlola ukuminyana ibhethri

Ngokuvamile abashayeli abanolwazi hlola kwebhetri futhi phezu kwabantu electrolyte. Le nqubo ikuvumela ukuba ufunde nje kuphela mayelana nesimo se-ketshezi esebenzayo, kodwa futhi ukuba ukuhlola ezingeni icala elifanayo. Ukuze wenze lo msebenzi usebenzisa hydrometer-umhloli. Nakuba abanye multimeters onobuhle ukusekela lesi sici. Noma kunjalo, umphumela nesilinganiso uvezwa njengoMahluleli ratio amagremu futhi cubic amasentimitha (g / ^cm.sup.3). Ngokwesibonelo, auto-accumulator ne ekhombisa kwabantu 1.24 g / ^cm3 ezibhekwa ngokufanele icala, operable futhi isilungele ukusetshenziswa. Ngakolunye uhlangothi, encishisiwe electrolyte kwabantu ka 0.08 g / cm ³ ubonisa ukuthi block has a icala ngaphansi kwengxenye.

Ngingaba hlola ibhethri ngaphandle amathuluzi ezikhethekile?

Kukhona futhi ezimweni lapho kulahlwa akuyona yokulinganisa zikagesi, kodwa kubalulekile unombono mayelana nesimo se-ibhethri. Indlela hlola ibhethri imoto kuleli cala? Empeleni, icala kungenziwa kulinganiselwa empirically. Practice test ne yokukhanya imoto. Ekuqaleni eligoqiwe umthwalo Imininingwane edingekayo yokuqhuba izibani, angahlolwa, ibhethri ezonikeza it.

Indlela ukukhetha multimeter ezifanelekile ibhethri?

Ukuze imoto udinga nginazo idivaysi encane kodwa sokusebenza. Desirably, idivayisi esebenza nge izinkomba ezifana capacitance, voltage, imvamisa futhi lokushisa. Lokhu iqoqo kwanele ukuze umsebenzisi kahle avivinye noma yiphi ibhethri. "Indlela ukuhlola block multimeter, okudinga kancane ezahlukene ukujula?" - liphinde Umbuzo ovamile, okuyinto okufanele sizindle ngilungele zokuthenga. I ezibizayo futhi kube nzima nakakhulu imitha, kulapho inani kwamadijithi, okusho isinqumo ezijulile, okusebenza, ngakho ukuze ulondoloze kule inzuzo akufanele.

isiphetho

ukunamathela abazihluphayo nezidingo imiyalelo yokusebenzisa ibattery, kubonakala, kufanele akhulule umsebenzisi kusukela ukuhlolwa amadivayisi njalo yizinkomba ahlukahlukene. Nokho, imibuzo mayelana nendlela ukuhlola umhloli ibhethri, kuyafaneleka ngokuphelele futhi ezimweni ezinjalo. Ulwazi wamanje ugesi Ukucaciswa kuzosiza ukusebenzisa engcono kwemithombo, ukukhetha ukushaja imingcele efanelekayo. Inqubo kakhulu okufanayo kokwenza ukuhlolwa akunzima ikakhulukazi uma ulandela uxhumano efanele oxhumana nabo kanye ilungelo lokufunda amagugu.
