LEEM-19 Yakakwana Yekuedza Instrument ye AC/DC Circuit neBridge

Tsanangudzo Pfupi:

Chiridzwa ichi chinobatanidza zviedzo zvakasiyana-siyana seDC bhiriji (kusanganisira bhiriji reruoko rumwe, bhiriji remaoko maviri, bhiriji risina kuenzana), AC bhiriji, RLC yenguva pfupi uye yakatsiga-inopindura, uye inonyatso dhizaini inoshanda yakawanda.

Nhanganyaya

1. Bridge kupikisa ruoko R1: 1Ω, 10Ω, 100Ω, 1000Ω, 10kΩ, 100kΩ, 1MΩ.
Kururama ± 0.1%;
2. Bhiriji rekudzivirira ruoko R2: gadzira seti yemabhokisi ekupikisa: 10kΩ + 10 × (1000+100+10+1) Ω, yakarurama ± 0.1%;
3. Bridge arm resistance R3: Gadzirisa seti mbiri dze synchronous resistance mabhokisi R3a, R3b, ayo akaiswa mukati pane imwechete kaviri-layer transfer switch, uye kupikisa kunochinja synchronously: 10 × (1000 + 100 + 10 + 0.1) Ω , Kururama ndiko: ± 0.1%;
4. Capacitor bhokisi: 0.001 ~ 1μF, zvishoma danho 0.001μF, kururama 2%;
5. Inductance bhokisi: 1～110mH, nhanho shoma 1mH, yakarurama 2%;
6. Multi-function power supply: DC 0～2V inogadziriswa magetsi, sine wave 50Hz～100kHz;square wave 50Hz
～1kHz;iyo frequency inoratidzwa ne5-digit frequency counter;
7. AC uye DC mbiri-chinangwa digital galvanometer: shandisa digital display voltmeter: range is 200mV, 2V;kupinza kunogona kusarudza AC, DC, isina kuenzana matatu modhi, pane senitivity kugadzirisa potentiometer.
8. Apo chiridzwa chacho chinoshandiswa sebhiriji-ruoko rumwe chete, chiyero chekuyera: 10Ω～1111.1KΩ, 0.1 level;
9. Apo chiridzwa chacho chinoshandiswa sebhiriji remagetsi maviri-ruoko, chiyero chekuyera: 0.01～111.11Ω, 0.2 level;
10. Kubudirira kwebhiriji risina kuenzana 10Ω～11.111KΩ, uye kukanganisa kunobvumirwa ndeye 0.5%;
11. Kune marudzi maviri ekuyera kupikisa mukati memudziyo: RX imwe chete, RX kaviri, maviri maviri e-capacitors ane maitiro akasiyana uye kurasikirwa kwakasiyana;marudzi maviri e inductances ane akasiyana inductances uye akasiyana Q maitiro;
12. Bhiriji remagetsi risina kuenzana rinofananidzwa ne sensor tembiricha ye thermistor, uye mutsara we digital thermometer yakagadzirwa nechisarudzo che 0.01 ℃;iyo thermistor inogona kushandiswa pamwe chete neiyo tembiricha sensor yeyakajairika sensor yekuedza chiridzwa.
13. Tsvakurudzo yekuedza: dzidza hukama pakati pe capacitance, kurasikirwa uye bias voltage;
14. Tsvakurudzo yekuedza: dzidza hukama pakati pe inductance uye bias ikozvino.
