Izimpawu Zesekethe ye-Multimeter Nezincazelo Zazo
Okuqukethwe
I-multimeter isetshenziselwa ukukala i-voltage, ukumelana, yamanje kanye nokuqhubeka. Ingelinye lamathuluzi kagesi asetshenziswa kakhulu. Into elandelayo okufanele uyenze ngemuva kokuthenga ukufunda ukuthi ungathatha kanjani ukufundwa ngendlela efanele.
Ingabe unayo i-multimeter yedijithali kodwa awazi ukuthi ungaqala kuphi? Ufike endaweni efanele. Sicela uqhubeke ufunda ukuze uthole konke odinga ukukwazi mayelana nezimpawu zesekhethi ye-multimeter nezincazelo zazo.
Izimpawu zama-Multimeter odinga ukuzazi
Izimpawu ze-multimeter yizo ozothola kumdwebo wesifunda.
Zihlanganisa;
1. Izimpawu ze-voltage multimeter
Ngenxa yokuthi ama-multimeters akala amandla kagesi aqondile (DC) kanye ne-alternating current (AC), abonisa uphawu lwe-voltage olungaphezu kolulodwa. Isikhundla se-voltage ye-AC yama-multimeter amadala yi-VAC. Abakhiqizi babeka umugqa we-wavy ngaphezu kwe-V ukuze uthole amamodeli amasha ukuze abonise i-voltage ye-AC.
Ku-voltage ye-DC, abakhiqizi babeka ulayini onamachashazi onomugqa oqinile phezu kwawo ngaphezu kwe-V. Uma ufuna ukukala i-voltage ngama-millivolts, okungukuthi u-1/1000 wevolthi, vula ukudayela ku-mV.
2. Izimpawu ze-multimeter zokumelana
Olunye uphawu lwesekethe ye-multimeter okufanele wazi ukuthi ukumelana. I-multimeter ithumela umsinga kagesi omncane ngokusebenzisa isekethe ukukala ukumelana. Uhlamvu lwesiGreki u-Omega (Ohm) luwuphawu lokumelana ne-multimeter. Ngeke ubone noma yimiphi imigqa ngenhla kophawu lokumelana ngoba amamitha awahlukanisi phakathi kokumelana kwe-AC ne-DC. (1)
3. Uphawu lwamanje lwe-multimeter
Ukala okwamanje ngendlela efanayo okala ngayo i-voltage. Kungaba i-alternating current (AC) noma i-direct current (DC). Qaphela ukuthi i-ampere noma i-ampere amayunithi wamanje, okuchaza ukuthi kungani uphawu lwe-multimeter lwamanje lungu-A.
Uma ubheka i-multimeter njengamanje, uzobona incwadi ethi "A" enomugqa we-wavy ngaphezu kwayo. Lena i-alternating current (AC). Uhlamvu “A” olunemigqa emibili—elidayishiwe futhi eliqinile ngaphezu kwalo—limele i-direct current (DC). Lapho ukala isimanje nge-multimeter, ukukhetha okutholakalayo i-mA yama-milliamp kanye ne-µA yama-microamp.
Ojeke nezinkinobho
I-DMM ngayinye iphuma nemikhondo emibili, emnyama nebomvu. Ungamangali uma i-multimeter yakho inezixhumi ezintathu noma ezine. Noma ngabe yini oyihlolayo inquma ukuthi uxhuma kuphi izintambo.
Nakhu ukusetshenziswa ngakunye;
- COM - ujeke ojwayelekile umnyama owodwa kuphela. Yilapho umthofu omnyama uya khona.
- A - Lapha yilapho uxhuma khona ucingo olubomvu lapho ukala amandla amanje afinyelela kuma-ampere ayi-10.
- mAmkA - Usebenzisa le sokhethi lapho ukala ngaphansi kwe-ampere sensitive current lapho i-multimeter inamasokhethi amane.
- mAOm - Isokhethi yokulinganisa ifaka i-voltage, izinga lokushisa kanye nomuzwa wamanje uma i-multimeter yakho iza namasokhethi amathathu.
- VOm - Lokhu kungokwazo zonke ezinye izilinganiso ngaphandle kwamanje.
Yazi i-multimeter yakho, ikakhulukazi phezulu kwesibonisi se-multimeter. Uyazibona izinkinobho ezimbili - eyodwa kwesokudla nenye kwesokunxele?
- Shift - Ukuze wonge isikhala, abakhiqizi bangase banikeze imisebenzi emibili ezindaweni ezithile zokudayela. Ukuze ufinyelele umsebenzi omakwe ngokuphuzi, cindezela inkinobho ethi Shift. Inkinobho ethi Shift ephuzi ingaba nayo noma ingabi nayo ilebula. (2)
- Bamba - cindezela inkinobho yokubamba uma ufuna ukumisa ukufundwa kwamanje ukuze kusetshenziswe kamuva.
Ukufingqa
Akufanele ube nenkinga yokuthola ukufundwa okunembile kwe-DMM. Sithemba ukuthi ngemva kokufunda lolu lwazi oluwusizo, uzizwa ujwayelene nezimpawu ze-multimeter.
