LEEM-11 kuyerwa kweVI Hunhu hweZvisina Mutsara Zvikamu
Mavoltmeter echinyakare edhijitari anowanzo kuve nekupikiswa kwemukati kwe10MΩ chete, izvo zvinounza mhosho huru pakuyera yakakwirira yekupikisa zvikamu.Muongorori anoshandisa ultra-yakakwirira mukati mekudzivirira voltmeter iyo yakakura kudarika 1000MΩ, ichideredza zvakanyanya kukanganisa kwehurongwa.Kune vanojairika vanopikisa pasi pe1MΩ, kukanganisa kwehurongwa kunokonzerwa nekupikiswa kwemukati kwevoltmeter kunogona kuregererwa, pasinei nevoltmeter mukati nekunze;nokuda kwekupikisa kwakanyanya, phototube uye zvimwe zvikamu zvakakura kudarika 1MΩ zvinogonawo kuyerwa nemazvo.Nekudaro, izvo zvechinyakare zviedzo zvekutanga kuwedzera zvirimo zvezviedzo zvitsva.
Main experimental content
1, yakajairika resistor voltammetric maitiro kuyerwa;diode uye voltage regulator diode voltammetric maitiro curve kuyerwa.
2, volt-ampere maitiro kuyerwa kwechiedza-emitting diode, tungsten bulbs.
3, mitsva yekuedza: kuyerwa kwevolt-ampere maitiro ekupikisa kwakanyanya uye capacitance.
4, Kuongorora kuyedza: kudzidza kwesimba rekupikiswa kwemukati memita pachiyero chevolt-ampere maitiro.
Main technical parameters
1, neyakagadziriswa magetsi emagetsi, inosiyana resistor, ammeter, yakakwirira-resistance voltmeter uye zvikamu zviri pasi pekuyedzwa, nezvimwe.
2, DC yakadzora magetsi ekupa: 0 ~ 15V, 0.2A, yakakamurwa kuita maviri mamakisi eyakaomarara uye yakanaka tuning, inogona kuramba ichigadziriswa.
3, Ultra-yakakwirira mukati mekudzivirira voltmeter : mana nehafu digit kuratidza, range 2V, 20V, yakaenzana input impedance> 1000MΩ, chisarudzo: 0.1mV, 1mV;4 mamwe mazinga: kupikisa kwemukati 1 MΩ, 10MΩ.
4, ammeter: mana nehafu digit kuratidza mita musoro, mana siyana 0 ~ 200μA, 0 ~ 2mA, 0 ~ 20mA, 0 ~ 200mA, mukati kuramba, zvichiteerana.
0 ~ 200mA, kupikisa kwemukati kwe: 1kΩ, 100Ω, 10Ω, 1Ω, maererano.
5, bhokisi rekupokana rakasiyana: 0 ~ 11200Ω, ine yakakwana ikozvino-yekudzivirira yekudzivirira yedunhu, haizopise zvikamu.
6, izvo zvakayerwa zvikamu: resistors, diode, voltage regulators, mwenje-emitting diode, magirobhu madiki, nezvimwe.
