LEEM-19 Sesebelisoa sa Boiteko se Felletseng sa Potoloho ea AC/DC le Borokho bo Hlahetsoeng

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

Tlhaloso e Khutšoanyane:

Sesebelisoa se kopanya liteko tse fapa-fapaneng tse kang borokho ba DC (ho kenyeletsoa borokho bo nang le letsoho le le leng, borokho bo nang le matsoho a mabeli, borokho bo sa leka-lekaneng), borokho ba AC, RLC ea nakoana le karabo e tsitsitseng, 'me ke sesebelisoa se nang le mekhoa e mengata e mengata.

1. Ho hanyetsa letsoho la borokho R1: 1Ω, 10Ω, 100Ω, 1000Ω, 10kΩ, 100kΩ, 1MΩ.
Ho nepahala ± 0.1%;
2. Ho hanyetsa letsoho la borokho R2: lokisa sete sa mabokose a ho hanyetsa: 10kΩ + 10 × (1000+100+10+1) Ω, ho nepahala ± 0.1%;
3. Borokho bo hanyetsanang le letsoho la borokho R3: Lokisa lihlopha tse peli tsa li-synchronous resistance boxes tsa R3a, R3b, tse kentsoeng ka hare ho sesebelisoa se le seng sa ho fetisa ka makhetlo a mabeli, 'me ho hanyetsa ho fetoha ka mokhoa o lumellanang: 10 × (1000 + 100 + 10 + 0.1) Ω , Ho nepahala ke: ± 0.1%;
4. Lebokose la capacitor: 0.001 ~ 1μF, bonyane mohato 0.001μF, ho nepahala 2%;
5. Lebokose la inductance: 1～110mH, bonyane mohato 1mH, ho nepahala 2%;
6. Motlakase oa lisebelisoa tse ngata: DC 0～2V phepelo ea matla a feto-fetohang, sine wave 50Hz～100kHz;lisekoere wave 50Hz
ho feta 1kHz;maqhubu a bonts'oa ke 5-digit frequency counter;
7. AC le DC galvanometer ea merero e 'meli ea digital: sebelisa voltmeter ea pontšo ea digital: sebaka ke 200mV, 2V;ho kenya letsoho ho ka khetha AC, DC, mekhoa e meraro e sa leka-lekaneng, ho na le potentiometer ea phetoho ea kutlo.
8. Ha sesebelisoa se sebelisoa e le borokho bo nang le letsoho le le leng, tekanyo ea ho lekanya: 10Ω～1111.1KΩ, boemo ba 0.1;
9. Ha sesebelisoa se sebelisoa e le borokho ba motlakase oa matsoho a mabeli, tekanyo ea ho lekanya: 0.01～111.11Ω, 0.2 level;
10. Sebaka se sebetsang hantle sa borokho bo sa leka-lekaneng ke 10Ω～11.111KΩ, 'me phoso e amohelehang ke 0.5%;
11. Ho na le mefuta e 'meli ea khanyetso e lekantsoeng ka hare ho sesebelisoa: RX e le' ngoe, RX habeli, mefuta e 'meli ea li-capacitor tse nang le bokhoni bo fapaneng le tahlehelo e fapaneng;mefuta e 'meli ea li-inductance tse nang le li-inductance tse fapaneng le litekanyetso tse fapaneng tsa Q;
12. Borokho ba motlakase bo sa leka-lekaneng bo tsamaisana le mochine oa mocheso oa mocheso oa mocheso, 'me mochine oa thermometer oa digital o entsoe ka qeto ea 0.01 ℃;thermistor e ka sebelisoa hammoho le sensor ea mocheso ea sesebelisoa se tloaelehileng sa teko ea sensor.
13. Teko ea lipatlisiso: ithuta kamano pakeng tsa capacitance, tahlehelo le bias voltage;
14. Teko ea lipatlisiso: ithuta kamano pakeng tsa inductance le bias current.
