LEEM-19 Chida Choyesera Chokwanira cha AC/DC Circuit and Bridge Featured Image

LEEM-19 Comprehensive Experimental Instrument for AC/DC Circuit and Bridge

Kufotokozera Kwachidule:

Chidacho chimagwirizanitsa zoyesera zosiyanasiyana monga mlatho wa DC (kuphatikizapo mlatho wa mkono umodzi, mlatho wa mikono iwiri, mlatho wosagwirizana), mlatho wa AC, RLC wanthawi yochepa komanso wokhazikika, ndipo ndi chipangizo chophatikizana kwambiri.

1. Bridge mkono kukana R1: 1Ω, 10Ω, 100Ω, 1000Ω, 10kΩ, 100kΩ, 1MΩ.
Zolondola ± 0.1%;
2. Kukaniza mkono wa Bridge R2: konzekerani mabokosi otsutsa: 10kΩ + 10 × (1000+100+10+1) Ω, kulondola ± 0.1%;
3. Kukaniza mkono wa Bridge R3: Konzani mabokosi awiri a synchronous resistance boxes R3a, R3b, omwe amaikidwa mkati pawotchi yofanana yamitundu iwiri, ndipo kukana kumasintha synchronously: 10 × (1000 + 100 + 10 + 0.1) Ω , Kulondola ndi: ± 0.1%;
4. Bokosi la capacitor: 0.001 ~ 1μF, sitepe yochepa 0.001μF, yolondola 2%;
5. Bokosi la inductance: 1～110mH, sitepe yochepa 1mH, kulondola 2%;
6. Mphamvu zamagetsi zamagetsi zambiri: DC 0～2V magetsi osinthika, sine wave 50Hz～100kHz;square wave 50Hz
～1 kHz;pafupipafupi amawonetsedwa ndi kauntala ya ma 5-digit frequency;
7. AC ndi DC galvanometer yapawiri-cholinga cha digito: gwiritsani ntchito voltmeter yowonetsera digito: osiyanasiyana ndi 200mV, 2V;kulowetsamo kungasankhe AC, DC, mitundu itatu yopanda malire, pali potentiometer yosintha mphamvu.
8. Pamene chidacho chikugwiritsidwa ntchito ngati mlatho wa mkono umodzi, mlingo woyezera: 10Ω～1111.1KΩ, mlingo wa 0.1;
9. Pamene chidacho chimagwiritsidwa ntchito ngati mlatho wamagetsi wamagetsi awiri, mlingo woyezera: 0.01～111.11Ω, 0.2 mlingo;
10. Njira yabwino ya mlatho wosagwirizana ndi 10Ω～11.111KΩ, ndipo cholakwika chovomerezeka ndi 0.5%;
11. Pali mitundu iwiri ya kukana koyezera mkati mwa chida: RX imodzi, RX iwiri, mitundu iwiri ya capacitor yokhala ndi mphamvu zosiyana ndi zotayika zosiyana;mitundu iwiri ya inductances yokhala ndi ma inductance osiyanasiyana ndi ma Q osiyanasiyana;
12. Mlatho wamagetsi wosalinganika umafanana ndi sensa ya kutentha kwa thermistor, ndipo thermometer yamagetsi yamagetsi imapangidwa ndi chisankho cha 0.01 ℃;Thermistor ingagwiritsidwe ntchito limodzi ndi sensa ya kutentha ya chipangizo choyesera chojambulira.
13. Kafukufuku wofufuza: phunzirani mgwirizano pakati pa capacitance, kutaya ndi kukondera;
14. Kafukufuku wofufuza: phunzirani mgwirizano pakati pa inductance ndi kukondera panopa.
