LEEM-11 Ma'auni na Halayen VI na abubuwan da ba sa kan layi
Voltmeters na al'ada na dijital gabaɗaya suna da juriya na ciki na 10MΩ kawai, wanda ke gabatar da babban kuskure yayin auna manyan abubuwan juriya.Mai gwadawa da ƙirƙira yana amfani da matsananci-high na ciki juriya voltmeter wanda ya fi girma fiye da 1000MΩ, yana rage kuskuren tsarin sosai.Don masu adawa na al'ada kasa da 1MΩ, kuskuren tsarin da ke haifar da juriya na ciki na voltmeter za a iya watsi da shi, ba tare da la'akari da voltmeter na ciki da na waje ba;don babban juriya, phototube da sauran abubuwan da suka fi 1MΩ kuma ana iya auna su daidai.Don haka, gwaje-gwaje na asali na gargajiya don faɗaɗa abun ciki na sababbin gwaje-gwaje.
Babban abun ciki na gwaji
1, talakawa resistor voltammetric halaye ma'auni;diode da lantarki mai sarrafa diode voltammetric halaye lankwasa ma'auni.
2, ma'aunin halayen volt-ampere na diodes masu fitar da haske, kwararan fitila na tungsten.
3, sabbin gwaje-gwajen: auna halayen volt-ampere na babban juriya da iya aiki.
4. Exploration gwaji: nazarin tasirin juriya na ciki na mita akan ma'auni na halayen volt-ampere.
Babban sigogi na fasaha
1, ta hanyar samar da wutar lantarki, m resistor, ammeter, high-resistance voltmeter da aka gyara karkashin gwaji, da dai sauransu.
2, DC sarrafa wutar lantarki: 0 ~ 15V, 0.2A, zuwa kashi biyu maki na m da lafiya kunna, za a iya ci gaba da gyara.
3, matsananci-high ciki juriya voltmeter: hudu da rabi lamba nuni, kewayon 2V, 20V, daidai shigar da impedance> 1000MΩ, ƙuduri: 0.1mV, 1mV;4 ƙarin jeri: juriya na ciki 1 MΩ, 10MΩ.
4, ammeter: hudu da rabi lambobi nuni mita shugaban, hudu jeri 0 ~ 200μA, 0 ~ 2mA, 0 ~ 20mA, 0 ~ 200mA, ciki juriya, bi da bi.
0 ~ 200mA, juriya na ciki na: 1kΩ, 100Ω, 10Ω, 1Ω, bi da bi.
5, Akwatin juriya mai canzawa: 0 ~ 11200Ω, tare da cikakkiyar da'irar kariyar iyaka na yanzu, ba zai ƙone abubuwan da aka gyara ba.
6, abubuwan da aka auna: resistors, diodes, voltage regulators, diodes-emitting diodes, kananan kwararan fitila, da dai sauransu.
