Letšoao la ho hanyetsa li-multimeter (Manual le linepe)

Multimeter ke ntho e hlokahalang bakeng sa ho hlahloba lisebelisoa tsa motlakase. Ho bohlokoa ho tseba letšoao la Om e le hore u le sebelise ka nepo. Batho ba motlakase ba tseba ho bala li-multimeter le matšoao a tsona, empa Joe/Jane ea tloaelehileng a ka hloka thuso, ke ka lebaka leo re leng teng.

Ho na le malebela le lintlha tse 'maloa tsa ho bala liparamente tse kang ohms, capacitance, volts le milliamp, mme mang kapa mang a ka tseba ho bala mithara.

Ho bala letšoao la khanyetso la multimeter, o hloka ho ba le kutloisiso ea mantlha ea motlakase, ho hanyetsa le ho tsoela pele ho bala; mohopolo mabapi le tlhahlobo ea diode le capacitance, lethathamo la matsoho le likoloi, le lihokelo le likonopo.

Matšoao a Multimeter ao u hlokang ho a tseba

Mona re tla tšohla voltage, resistance and continuity.

• Voltage e thusa ho lekanya motlakase o tobileng hona joale (DC) le motlakase oa alternating current (AC). Mohala oa wavy o ka holimo ho V o bontša motlakase oa AC. Mohala oa V o matheba le o tiileng o bolela motlakase oa DC. mV e nang le matheba a le mong le mohala o le mong oa wavy e bolela millivolts AC kapa DC.
• Hajoale e ka ba AC kapa DC mme e lekantsoe ka li-ampere. Mohala oa wavy o emetse AC. A e nang le mola o matheba a le mong le mola o le mong o tiileng o supa DC.(1)
• Multimeter e boetse e sebelisoa ho lekola potoloho e bulehileng potolohong ea motlakase. Ho na le liphetho tse peli tsa tekanyo ea khanyetso. Ho e 'ngoe, potoloho e lula e bulehile' me meter e bontša khanyetso e sa feleng. E 'ngoe e bala e koetsoe, moo potoloho e balang zero ebe e koala. Maemong a mang, mitha e tla lla ka mor'a ho lemoha ho tsoela pele.(2)

Liteko tsa diode le capacitance

Mosebetsi oa tlhahlobo ea diode o re bolella hore na diode ea sebetsa kapa che. Diode ke karolo ea motlakase e thusang ho fetolela AC ho DC. Teko ea capacitance e kenyelletsa li-capacitor, e leng lisebelisoa tsa polokelo ea litefiso, le mitha e lekanyang tefiso. Multimeter e 'ngoe le e' ngoe e na le lithapo tse peli le mefuta e mene ea li-connectors tseo u ka li kopanyang. Lihokelo tse 'ne li kenyelletsa sehokelo sa COM, sehokelo, mAOm Jack, le mAmkA sehokedi.

Sebaka sa matsoho le sa likoloi

Mefuta e 'meli ea li-multimeter e ka sebelisoa. E 'ngoe ke multimeter ea analog ha e' ngoe ke multimeter ea digital. Multimeter ea analog e kenyelletsa litlhophiso tse ngata tsa mefuta e mengata 'me e na le pointer ka hare. E ke ke ea sebelisoa ho lekanya litekanyo tse hlokolosi kaha pointer e ke ke ea kheloha ho feta mefuta e mengata. Pointer e tla kheloha ho fihlela boholo ba eona bo hole bo khuts'oane mme tekanyo e ke ke ea feta moeli.

DMM e na le litlhophiso tse 'maloa tse ka khethoang ka ho daela. Metara e ikhethela sebaka ka bo eona kaha ha e na li-setting tsa marang-rang. Li-multimeter tsa othomathike li sebetsa betere ho feta li-multimeter tse fapaneng.
