LEEM-18 AC buundada tijaabada
Tijaabooyin
1. Baro oo baro xaaladaha dheelitirka iyo mabaadi'da cabbiraadda buundada AC;xaqiijiyo xaaladaha dheelitirka ee buundada AC;
2. Cabbir awoodda iyo lumista korontada;is-dhaqdhaqaaqa iyo cunsurkeeda tayada gariiradda iyo isdhaxgalka wadaagga ah iyo xuduudaha kale ee korantada.
3. Nashqadaynta buundooyinka AC kala duwan ee cabbirka dhabta ah.
Qodobbada ugu muhiimsan ee farsamada
1. Ilaha signalka tamarta ee la dhisay: inta jeer ee 1kHz ± 10Hz, baaxadda korantada wax soo saarka: 1.5Vrms;
2. Shaashadda dhijitaalka ah ee ku dhex jirta AC voltmeter: Cabbirka cabbiraadda korantada AC: 0~2V, bandhig dhijitaal ah oo saddex iyo badh ah;
3. Mitir joogto ah oo dhijitaalka ah oo afar-god ah oo LED ah oo ku dhex-dhisan, cabbirka cabbirka: 20Hz~10kHz, khalad cabbirka: 0.2%;
4. Tilmaame eber AC ah oo lagu dhex dhisay: oo leh ilaalin xad dhaaf ah, madax mitir ah malaha;dareenka ≤1 × 10-8A / div, si joogto ah loo hagaajin karo;
5. Iska caabbinta cududda buundada ee ku dhex jirta:
Ra: wuxuu ka kooban yahay todobo iska caabin AC ah oo kala ah 1, 10, 100, 1k, 10k, 100k, 1MΩ, oo sax ah 0.2%
Rb: Ka kooban 10 × (1000+100+10+1+0.1)Ω sanduuqa iska caabinta AC, oo sax ah 0.2%
Rn: Ka kooban 10K+10×(1000+100+10+1)Ω Sanduuqa iska caabinta AC, oo sax ah 0.2%
6. Kapacitor-ka caadiga ah ee lagu dhex dhisay, inductance caadiga ah Ln;
Awoodda caadiga ah: 0.001μF, 0.01μF, 0.1μF, saxnaanta 1%;
Inductance caadiga ah: 1mH, 10mH, 100mH, saxnaanta 1.5%;
7. Rx caabbinta la qiyaasay, capacitance CX iyo inductance LX oo leh qiimayaal iyo waxqabadyo kala duwan ayaa lagu soo daray.
