Uvavanyo lweBridge ye-AC ye-LEEM-18

Iimvavanyo
1. Funda kwaye ube nobuchule kwiimeko zokulinganisela kunye nemigaqo yokulinganisa yebhulorho ye-AC; qinisekisa iimeko zokulinganisela zebhulorho ye-AC;
2. Linganisa i-capacitance kunye ne-dielectric loss; i-self-inductance kunye ne-coil quality factor yayo kunye ne-mutual inductance kunye nezinye iiparameter zombane.
3. Yila iibhulorho ezahlukeneyo ze-AC ukuze zilinganiswe ngokwenene.

Iiparameters eziphambili zobugcisa
1. Umthombo wesignali yamandla eyakhelwe ngaphakathi: i-frequency 1kHz±10Hz, i-amplitude ye-voltage yokuphuma: 1.5Vrms;
2. Isibonisi sedijithali esakhelwe ngaphakathi I-voltmeter ye-AC: Uluhlu lokulinganisa i-voltage ye-AC: 0～2V, isibonisi sedijithali ezintathu ezinesiqingatha;
3. Imitha yefrikhwensi yedijithali ye-LED enamanani amane eyakhelwe ngaphakathi, uluhlu lokulinganisa: 20Hz ～10kHz, impazamo yokulinganisa: 0.2%;
4. I-AC zero-pointer eyakhelwe ngaphakathi: inokhuseleko lokugqithisa, akukho ntloko yemitha; uvakalelo ≤1×10-8A/div, ehlengahlengiswa rhoqo;
5. Ukumelana nengalo yebhulorho eyakhelwe ngaphakathi:
I-Ra: inee-AC resistances ezisixhenxe ze-1, 10, 100, 1k, 10k, 100k, 1MΩ, kunye nokuchaneka kwe-0.2%
I-Rb: Yenziwe ngebhokisi yokumelana ne-AC eyi-10×(1000+100+10+1+0.1)Ω, echanekileyo yi-0.2%
I-Rn: Yenziwe ngebhokisi yokumelana ne-AC ye-10K+10×(1000+100+10+1)Ω, echanekileyo yi-0.2%
6. I-capacitor esemgangathweni eyakhelwe ngaphakathi i-Cn, i-inductance Ln esemgangathweni;
Umthamo oqhelekileyo: 0.001μF, 0.01μF, 0.1μF, ukuchaneka yi-1%;
Ukungena okuqhelekileyo: 1mH, 10mH, 100mH, ukuchaneka yi-1.5%;
7. I-Rx yokumelana elinganisiweyo, i-capacitance CX kunye ne-inductance LX enexabiso kunye nokusebenza okwahlukeneyo ifakiwe.
