Ukuhlolwa Kwebhuloho Elinemisebenzi Eminingi le-LEEM-23 Isithombe Esifakiwe

Ukuhlolwa kwebhuloho lemisebenzi eminingi le-LEEM-23

Incazelo emfushane:

Ithuluzi lihlanganisa imisebenzi ehlukahlukene yebhuloho elingalodwa, ibhuloho elingalodwa, kanye nebhuloho elingalingani, elingalinganisa ukumelana nezintambo ezimbili, izintambo ezintathu, kanye nezintambo ezine, okwenza umsebenzisi abe "uchwepheshe" ekusebenziseni amabhuloho.

Sithumelele i-imeyili

Imininingwane Yomkhiqizo

Amathegi Omkhiqizo

Amapharamitha obuchwepheshe ayinhloko
1. Ukumelana nengalo yebhuloho R1: Lungiselela isethi yokumelana okunembile: 10Ω, 100Ω, 1000Ω, 10kΩ, okuguqulwa uxhumano lwepulaki ye-short-circuit, futhi ukunemba kokumelana kungu-±0.1%;
2. Ukumelana nengalo yebhuloho R2: Lungiselela isethi yamabhokisi okumelana: 10×(1000+100+10+1)Ω, ukunemba kokumelana kungu: ±0.1%, ±0.2%, ±1%, ±2%;
3. Ukumelana nengalo yebhuloho R3: Lungiselela amasethi amabili amabhokisi okumelana R3a, R3b, afakwe ngaphakathi kuswishi yokudlulisa efanayo enezingqimba ezimbili, futhi ukumelana kuyashintsha ngasikhathi sinye: 10×(1000+100+10+1+0.1)Ω, ukumelana
Ukunemba kungukuthi: ±0.1%, ±0.2%, ±1%, ±2%, ±5%;
4. I-RN ejwayelekile yokumelana: Amanani okumelana yilawa: 10Ω, 1Ω, 0.1Ω, 0.01Ω, kanye namaphuzu okunemba kokumelana
Ngaphandle: ±0.1%, ±0.1%, ±0.2%, ±0.5%, ingaxhunywa ngaphandle;
5. Ukumelana okwakhelwe ngaphakathi okumele kulinganiswe: I-Rx eyodwa: 1kΩ, 0.25W, ukungaqiniseki: 0.1%; I-Rx kabili: 0.2 ohm, 0.25W, ukungaqiniseki: 0.2%. Lawa ma-resistor amabili angasetshenziswa ukulinganisa ibhuloho noma ukuhlola ukuthi ibhuloho lisebenza kahle yini.
6. I-galvanometer yedijithali: sebenzisa i-voltmeter yokubonisa yedijithali engu-4 nengxenye: ububanzi bungu-200mV, 2V. Ukunemba kokubonisa kwe-galvanometer yedijithali kungu: (ububanzi obungu-0.1% ± amagama angu-2). I-Galvanometer ingaxhunywa ngaphandle;
7. Ukunikezwa kwamandla amaningi: Ukunikezwa kwamandla okushintshashintshayo okungu-0～2V, ukunikezwa kwamandla okungu-3V, 9V.
8. Uma ithuluzi lisetshenziswa njengebhuloho elingalodwa, ububanzi bokulinganisa: 10Ω～1111.1KΩ, izinga elingu-0.1;
9. Uma ithuluzi lisetshenziswa njengebhuloho likagesi elinezandla ezimbili, ububanzi bokulinganisa: 0.01 ～111.11Ω, izinga elingu-0.2;
10. Ububanzi obusebenzayo bebhuloho elingalingani ngu-10Ω～11.111KΩ, kanti iphutha elivumelekile lingu-0.5%;
11. Uma usetha ibhuloho elingalingani, ithuluzi lidinga ukuhlonyiswa ngenzwa yokumelana noma idivayisi yokulawula izinga lokushisa.
12. Zonke izinhlobo zamabhuloho kagesi afanayo zingenziwa ngezifiso.
