Mokhoa oa ho lekola sensor ea mocheso ka multimeter

Li-gauge tse fosahetseng kapa lisensara tsa mocheso li atisa ho fana ka liphello tse sa utloahaleng ha li sebelisoa, e leng ho bakang maeto a theko e boima ho ea ho mechini le tlhokomelo e sa hlokahaleng, kahoo ho rarolla mathata ke ntho ea bohlokoa. U hloka sensor ea mocheso e felletseng e nang le ho nepahala ha maemo a pele.

Tekanyo ea mocheso kapa gauge e thusa ho boloka mocheso o sa fetoheng bakeng sa ho sebetsa hantle ha enjine.

Ho u tataisa mehatong ea ho lekola boemo ba thermometer ea hau, ke hlalositse mekhoa e mene e qaqileng ea ho netefatsa hore thermometer ea hau e sebetsa hantle.

Ka kakaretso, ho hlahloba le ho rarolla bothata ba li-sensor tsa mocheso ho kenyelletsa:

1. Lithapo tsa ho hlahloba le maemo a tloaelehileng

2. Ho hlahloba letšoao la Ohm ho tloha ho Transmitting Device

3. Ho hlahloba letšoao la ohm ka tekanyo ea khatello le qetellong

Ho hlahloba tekanyo ea khatello ka boeona

Tataisong ena, re tla feta mehato e kaholimo ka botlalo.

U tla hloka lisebelisoa tse latelang:

• Digital multimeter
• Lithapo tse hokelang
• Mohloli oa Matla (1)
• mocheso oa mocheso
• Calculator, pene le pampiri
• Sehlopha sa moromelli
• Koloi

Mokhoa oa ho Rarolla Mathata ho Sensor e hlolehileng kapa e kantle e tloaelehileng ea mocheso

Latela mehato ena ho hlahloba ts'ebetso ea thermometer ea hau:

1. Lithapo tsa ho hlahloba le maemo a tloaelehileng. Haeba lithapo li sa hokeloa hantle, kapa haeba li robehile li bile li khaohile, mochine o lemohang mocheso o ke ke oa sebetsa hantle kapa hona ho khaotsa ho sebetsa. Ho hlahloba sebaka se tloaelehileng sa terata, tšoara teko e le 'ngoe ho terata ea fatše 'me u kopanye ntlha e' ngoe ea teko ho palo ea motlakase ea motlakase (fatše) ho etsa hore multimeter e sebetse e le ammeter. E tla bonts'a boleng bo fapaneng skrineng. Theko e tlameha ho ba zero bakeng sa terata e theohileng, ho seng joalo phoso e etsahala.
2. Ho hlahloba lets'oao la ohm le tsoang ho transmitter. Ka makhetlo a mangata u iphumana u le boemong boo ho hlokahalang hore u nke sebaka sa mochine oa mochine oa tekanyo ea mocheso koloing ea hau. Ho lekola mofuta oa ohm, o hloka ho hokahanya sekala ho multimeter ea hau, ho etsa bonnete ba hore o hokahanya li-terminals tse nepahetseng ka nepo (ke hore, e ntle ho ea ho e ntle le e mpe ho isa ho e mpe). Etsa bonnete ba hore u bala li-sensor sebakeng se se nang letho le se felletseng e le hore u ka khetha kopano e nepahetseng ea sensor bakeng sa koloi ea hau. Kamora ho hokela transmitter ho DMM maemong a ohm (o ka khetha li-ohm tse 2000 - o ka ngopa li-terminals tsa transmitter ho fumana 'malo o nepahetseng haholoanyane), ngola boleng ba khanyetso kapa sebaka. Ho tseba mofuta oa ho hanyetsa ha sensor ea hau ho tla u thusa ho khetha sensor e lumellanang ea koloi ea hau.
3. Mokhoa oa ho hlahloba lets'oao la ohm ka tekanyo ea khatello. Ho lekanya khanyetso, e tsejoang hape e le gauge resistance, etsa bonnete ba hore ha ho na motlakase o phallang ka lebokoseng la motho ea romelang kapa karolo efe kapa efe eo u ka ratang ho e leka, ebe u kenya li-plug / li-plug tse ntšo le tse khubelu ho COM le ho omega VΩ ka ho latellana, fetola multimeter. ka har'a mokhoa oa ho hanyetsa o ngotsoeng Ω ebe o beha sebaka ho ea holimo. Kopanya li-probes ho transmitter kapa sesebelisoa seo u batlang ho se hlahloba (hlokomoloha polarity kaha ho hanyetsa ha ho na tataiso), fetola mefuta e mengata ho lekanya 'me u fumane boleng ba OL, boo hangata e leng 1OL.
4. Qetellong, hlahloba sensor. U ka etsa sena ka ho etsa se latelang:

• Hakolla tekanyo ea mocheso sebakeng se romelloang.
• Fetolela senotlolo (ho khantša) sebakeng sa "ho" on "
• Hokela terata ea sensor ea mocheso ho enjene u sebelisa li-jumpers.
• Etsa bonnete ba hore tekanyo ea tekanyo ea mocheso e pakeng tsa ho bata le ho chesa
• Fetolela senotlolo sebakeng se ngotsoeng "Off."
• Sheba li-fuse tse fofang ka koloing le tse hokahantsoeng le sensor ea mocheso, 'me u li nkele sebaka haeba li foka.
• Theola terata (jumper) e hoketsoeng setsing sa sensor haufi le enjene.
• Ebe o bula senotlolo sa ho hotetsa ntle le ho qala koloi. Ka nako ena, haeba mocheso oa mocheso o bontša "ho chesa", ho bolela hore ho na le terata e robehileng mochine oa ho fetisa 'me u lokela ho lokisa mochine oa mocheso.

Ho akaretsa

Ke tšepa hore thupelo ena e u thusitse hore u se ke ua tlameha ho ea ho mechini makhetlo a mangata ho ea hlahloba kapa ho lokisa sensor. U ka e etsa u le mong 'me ua fokotsa litšenyehelo tsa koloi ea hau. (2)

Sheba tse ling tsa lingoliloeng tsa rona tse ka tlase.

• Mokhoa oa ho lekola ho tsoa ha betri ka multimeter
• Mokhoa oa ho lekola sesebelisoa sa lebone ka multimeter
• Mokhoa oa ho lekola sensor ea terata e meraro ka multimeter
