Imigqa emibili eqondile enomugqa ovundlile ingeyokuhlola ibhethri.

Zonke lezi zimpawu zingatholakala endaweni yesikali ye-multimeter. Ngakho-ke, uma umusha kumamodeli we-Cen Tech, qiniseka ukuthi uyawahlola ngaphambi kokuthi uqalise.

Amachweba nezikhonkwane

I-multimeter ye-Cen Tech iza nemikhondo emibili; omnyama nobomvu. Ezinye izintambo zingaba neziqeshana zengwenya. Futhi abanye bangase bangabi.

Intambo emnyama ixhuma embobeni ye-COM ye-multimeter. Futhi intambo ebomvu ixhuma ngembobo ye-VΩmA noma imbobo engu-10ADC.

Ithiphu Esheshayo: Uma ukala imanje ngaphansi kuka-200 mA, sebenzisa imbobo ye-VΩmA. Kuma-currents angaphezu kuka-200mA, sebenzisa imbobo ye-10ADC.

Ukusebenzisa yonke imisebenzi eyisikhombisa ye-multimeter ye-Cen Tech

Kulesi sigaba, uzofunda ukusebenzisa imisebenzi eyisikhombisa ye-multimeter ye-Cen Tech. Lapha ungafunda ekulinganiseni ukumelana nokuhlola ukushajwa kwebhethri.

Kala ukumelana

Xhuma i-blackjack embobeni ye-COM.
Xhuma isixhumi esibomvu embobeni ye-VΩmA.
Vula i-multimeter.
Guqula ukudayela kube uphawu lwama-200 endaweni ye-Ω (Ohm).
Thinta izintambo ezimbili futhi uhlole ukumelana (kufanele kube zero).
Xhuma izintambo ezibomvu nezimnyama ezintanjeni zesekhethi.
Bhala phansi ukumelana.

Ithiphu Esheshayo: Uma uthola okunye okufundwayo, shintsha izinga lokuzwela. Isibonelo, vula ukudayela ku-2000.

Ungahlola futhi ukuqhubeka usebenzisa izilungiselelo zokumelana. Vula ukudayela ku-2000K futhi uhlole isekethe. Uma ukufundwa kungu-1, isifunda sivuliwe; uma ukufundwa kungu-0, kuyisifunda esivaliwe.

Isilinganiso samandla kagesi

Uma kuziwa kuma-transistors, kunezinhlobo ezimbili; I-NNP kanye ne-PNP. Ngakho-ke, ngaphambi kokuhlolwa, udinga ukunquma uhlobo lwe-transistor.

Ngaphezu kwalokho, amatheminali amathathu e-transistor aziwa ngokuthi yi-emitter, isisekelo, kanye nomqoqi. Iphinikhodi emaphakathi isisekelo. Iphinikhodi engakwesokudla (ngakwesokudla) yi-emitter. Futhi iphinikhodi yesokunxele ingumqoqi.

Hlala njalo uhlonza uhlobo lwe-transistor nezikhonkwane ezintathu ngendlela efanele ngaphambi kokuxhuma i-transistor ku-multimeter ye-Cen Tech. Ukusebenzisa okungalungile kungalimaza i-transistor noma i-multimeter.

Ukuhlola ibhethri (isilinganiso se-voltage yebhethri)

Vula ukudayela endaweni yokuhlola ibhethri (eduze nendawo ye-ACV).
Xhuma i-blackjack embobeni ye-COM.
Xhuma isixhumi esibomvu embobeni ye-VΩmA.
Vula i-multimeter.
Xhuma intambo ebomvu kutheminali yebhethri ephozithivu.
Xhuma intambo emnyama kutheminali enegethivu.
Qhathanisa ukufundwa ne-voltage yebhethri yegama.

Nge-Cen Tech Multimeter, ungakwazi ukuhlola amabhethri angu-9V, C-cell, D-cell, AAA kanye ne-AA. Kodwa-ke, ungawahloli amabhethri emoto i-6V noma i-12V. Sebenzisa i-voltmeter esikhundleni salokho.

kubalulekile: I-athikili engenhla imayelana nomsebenzi oyisikhombisa imodeli ye-Cen Tech 98025. Nokho, imodeli ye-95683 ihluke kancane kumodeli ye-98025. Isibonelo, uzothola imbobo ye-10A esikhundleni sembobo ye-10ADC. Ngaphezu kwalokho, ungathola indawo ye-ACA ye-AC. Ungakhohlwa ukufunda incwadi ye-Centech DMM uma udidekile ngalokhu.
