Ukuhlolwa kwebhuloho le-AC le-LEEM-18

Ukuhlolwa
1. Funda futhi ube yingcweti ezimweni zokulinganisela kanye nezimiso zokulinganisa zebhuloho le-AC; qinisekisa izimo zokulinganisela zebhuloho le-AC;
2. Kala amandla kanye nokulahlekelwa yi-dielectric; ukuzilawula kanye nekhwalithi yekhoyili kanye nokuguquguquka okuhlangene kanye nezinye izilinganiso zikagesi.
3. Yakha amabhuloho ahlukahlukene e-AC ukuze ulinganise ngempela.

Amapharamitha obuchwepheshe ayinhloko
1. Umthombo wesignali yamandla owakhelwe ngaphakathi: imvamisa 1kHz±10Hz, i-amplitude ye-voltage yokuphuma: 1.5Vrms;
2. Isibonisi sedijithali esakhelwe ngaphakathi I-voltmeter ye-AC: Ububanzi bokulinganisa i-voltage ye-AC: 0～2V, isibonisi sedijithali ezintathu nengxenye;
3. Imitha yemvamisa yedijithali ye-LED enamadijithi amane eyakhelwe ngaphakathi, ububanzi bokulinganisa: 20Hz ～10kHz, iphutha lokulinganisa: 0.2%;
4. I-AC zero-pointer eyakhelwe ngaphakathi: enokuvikelwa kokulayisha ngokweqile, ayikho ikhanda lemitha; ukuzwela ≤1×10-8A/div, elungisekayo njalo;
5. Ukumelana nengalo yebhuloho eyakhelwe ngaphakathi:
I-Ra: iqukethe ukumelana kwe-AC okuyisikhombisa okungu-1, 10, 100, 1k, 10k, 100k, 1MΩ, ngokunemba okungu-0.2%
I-Rb: Yakhiwe ngebhokisi lokumelana ne-AC elingu-10×(1000+100+10+1+0.1)Ω, ngokunemba okungu-0.2%
I-Rn: Yakhiwe ngebhokisi lokumelana ne-AC elingu-10K+10×(1000+100+10+1)Ω, ngokunemba okungu-0.2%
6. I-capacitor ejwayelekile ye-Cn eyakhelwe ngaphakathi, i-inductance ejwayelekile ye-Ln;
Amandla ajwayelekile: 0.001μF, 0.01μF, 0.1μF, ukunemba okungu-1%;
Ukungena okujwayelekile: 1mH, 10mH, 100mH, ukunemba okungu-1.5%;
7. Ukumelana okulinganisiwe kwe-Rx, i-capacitance CX kanye ne-inductance LX enamanani ahlukene kanye nokusebenza kufakiwe.
