OL inorevei pane multimeter?

Kuverenga kweOL multimeter kunorevei? Uyu mubvunzo wakajairika waunowanzo kusangana ne "OL" kuverenga kana uchishandisa yako yakakosha multimeter.

Sezvo isu tichifambira mberi, isu tichanyatso tarisisa izvo OL inomiririra pane multimeter.

OL Kuverenga pane multimeter

Iri chidimbu che "open loop". ichitaura kushaikwa kwemaitiro emhinduro. Iri izwi rinoreva chero mamiriro aunenge uchiedza kuyera chiratidzo chemagetsi usingashandisi mhinduro. Nokudaro, inoshandiswa kune zvakasiyana-siyana zvemidziyo.

OL inogona kuva nechirevo chakasiyana. Zvisinei, iyi ndiyo imwe nzira yekuratidza kushaikwa kwekuenderera mberi. Inogona zvakare kureva kudarika muganho wevoltage uye kuyerwa kwazvino.

Nhamba 1. Kuenderera mberi kwekuedza 

Kana bvunzo isingazivikanwe, chiratidziro chicharatidza imwe kana OL (yakavhurika loop). Izvi zvinoreva kuti hapana kuenderera mberi. Magetsi haakwanise kupfuura kubva pakuferefeta kuenda kuprobe kana pasina nzira yayo.

Nhamba 2. Test voltage 

Kana iyo frequency yakadzikira, skrini icharatidza imwe kana OL, zvichiratidza kuti haisi kuwanikwa kana kuremerwa. Izvi hazvikuvadze kana kukuvadza multimeter yako, asi zvinokurudzira kugadzirisa dial.

Nhamba 3. Resistance test

Kana iyo element kana dunhu rauri kuyera risina kuenderera, iyo skrini inoratidza imwe kana OL. Somugumisiro, ine kuramba kusingagumi.

#4: Kuedza Kuyerera Kwezvino

Pakuyera matunhu azvino, chiratidziro chinoratidza ini kana OL kana yako yakakosha multimeter yakawandisa. Izvi zvinobatsira pakuedza injini.

Saka kuverenga kweOL panguva yekuyedzwa kwemagetsi kungaratidza kuti chimwe chinhu chakashata, zvichienderana nemamiriro ako ezvinhu. Pamwe kuvimbika kwezvinhu zviri kuongororwa, kana kuwanda kwezvino.

Kuramba kusingagumi pane multimeter

Sezvambotaurwa, OL inoitika pamita kana kuramba kusingapere. Izvi zvinoratidza kuti chikamu chiri kuyerwa hachina magetsi anoyerera nepakati pechinhu kana dunhu. Iwe unogona kuyera kuramba mu ohms ne multimeter.  

Ngatitorei pombi semuenzaniso. Iwe unogona kushandisa kushorwa kuverenga huwandu hwemvura inoyerera kuburikidza nepombi. Sezvo pombi yakavharwa ine kukwirira kwepamusoro, mvura shoma inopfuura nayo. Kune rumwe rutivi, pombi yakavharwa iyo isingabvumiri mvura kupfuura ine inopikisa yakakwirira. Inozivikanwa se infinite resistance. (1)

Pakuyera magetsi ikozvino, multimeter bvunzo dzinoita zvakafanana. Kana iyo ohm bvunzo yakawandisa, haizokwanise kuona iripo. Icharatidza "OL" zvinoreva kuvhura loop. Kana izvi zvikaitika, iwe unozofanirwa kuderedza kuramba - kungave nekukwesha matipi ekuongorora kana kushandisa yakakosha probes.

OL uye 0 kana uchitarisa kuramba

"OL" zvinoreva "kuvhura loop". Izvi zvinoreva kuti iyo multimeter haigone kuyera kukosha kwekupikisa iyo yakaderera pane yazvino. Meta inoedza kuratidza kuyerwa uku, asi nekuti haigone kuratidza nhamba huru, inoratidza "OL". Izvi zvinogona kuitika pakuyera kushomeka kwakanyanya kana kana uchishandisa yakaderera voltage mudunhu iri pasi pekuyedzwa.

0 inogona kucherechedzwa munharaunda yakavhurika kana pasina kubatana pakati pematerminals maviri. Hapana zvikamu zvakabatana nepini yekupinza analog pane microprocessor. Inoratidzwa se "L" mune mamwe saizi. Iyo yakavhurika "O" dunhu idunhu umo kuenderera kwakaputswa nekuda kwekuputsika munzira yazvino. Dunhu rakavharwa rakakwana uye rine kuenderera kwakanaka mukati mese. Dunhu rakavharwa rinogadzira nzira yakakwana yekufamba kwesimba rinoshanda kubva pachitubu kuenda kumutoro. (2)

Nekudaro, kana iwe ukaisa yakafanana dunhu pabhodhi rechingwa, mhedzisiro inogona kusiyana. Izvo zvinoenderana nekuti vangani vanopikisa vakabatana kune alligator clip kumagumo ega ega. Dai 0 ohms aivepo, aiita sewaya obatanidza mapini maviri aya pamwechete. Izvi zvichaguma nekusabatana uye kuverenga kwako "0" kana dunhu rakavhurika.

Pazasi pane mamwe multimeter bvunzo yekudzidza tutorials isu takanyora. Unogona kuzvitarisa kana kuisa bookmark kuti uverenge gare gare.
