LEEM-18 AC Bridge Kuedza
Miedzo
1. Dzidza uye kugona mamiriro ekuenzanisa uye kuyerwa kwemisimboti ye AC zambuko;chengetedza mamiriro ekuenzanisa e AC bhiriji;
2. Kuyera capacitance uye dielectric kurasikirwa;self-inductance uye yayo coil mhando chinhu uye mutual inductance uye mamwe magetsi paramita.
3. Gadzira akasiyana ma AC mabhiriji ekuyera chaiko.
Iyo huru yehunyanzvi parameters
1. Yakavakirwa-mukati simba chiratidzo sosi: frequency 1kHz ± 10Hz, goho voltage amplitude: 1.5Vrms;
2. Yakavakirwa-mukati dhijitari inoratidza AC voltmeter: AC voltage kuyerwa kwemhando: 0~2V, matatu nehafu dhijitari kuratidza;
3. Yakavakwa-in-man-mana mana LED digital frequency mita, kuyera chiyero: 20Hz~10kHz, kuyera kukanganisa: 0.2%;
4. Yakavakwa-mu AC zero-pointer: ine kuchengetedzwa kwepamusoro, isina musoro wemamita;kunzwa ≤1 × 10-8A / div, inoramba ichigadziriswa;
5. Yakavakirwa-mukati bhiriji kuramba ruoko:
Ra: ine zvinomwe zvinopikisa AC zve1, 10, 100, 1k, 10k, 100k, 1MΩ, ine chokwadi che 0.2%
Rb: Yakagadzirwa ne10 × (1000+100+10+1+0.1)Ω AC kuramba bhokisi, ine chokwadi che0.2%
Rn: Yakagadzirwa ne10K+10×(1000+100+10+1)Ω AC kuramba bhokisi, ine chokwadi che0.2%
6. Yakavakwa-mukati capacitor Cn, standard inductance Ln;
Standard capacitance: 0.001μF, 0.01μF, 0.1μF, yakarurama 1%;
Standard inductance: 1mH, 10mH, 100mH, yakarurama 1.5%;
7. Iyo yakayerwa kuramba Rx, capacitance CX uye inductance LX ine maitiro akasiyana uye maitiro anosanganisirwa.
