LEEM-19 IsiXhobo soMfuniselo esiBanzi se-AC/DC yeSekethe kunye neBridge eFakelweyo yoMfanekiso

LEEM-19 IsiXhobo soMfuniselo esiBanzi se-AC/DC seSekethe kunye neBridge

Inkcazelo emfutshane:

Isixhobo sidibanisa iimvavanyo ezahlukeneyo ezifana ne-DC bridge (kubandakanya ibhuloho yengalo enye, ibhuloho yengalo ephindwe kabini, ibhuloho engalinganiyo), ibhuloho ye-AC, i-RLC edlulayo kunye nempendulo ezinzileyo, kwaye iyisixhobo esibanzi esibanzi.

Intshayelelo

1. Ukuxhathisa ingalo yeBridge R1: 1Ω, 10Ω, 100Ω, 1000Ω, 10kΩ, 100kΩ, 1MΩ.
Ukuchaneka ±0.1%;
2. Ukumelana nengalo yebhulorho i-R2: cwangcisa isethi yeebhokisi zokumelana: 10kΩ + 10 × (1000+100+10+1) Ω, ukuchaneka ± 0.1%;
3. Ukuchasana kwengalo yebhulorho i-R3: Lungiselela iiseti ezimbini zeebhokisi zokuxhathisa i-synchronous R3a, i-R3b, ezifakwe ngaphakathi kwi-switch yokudlulisa i-double-layer efanayo, kunye nokutshintsha ukuchasana ngokuhambelanayo: 10 × (1000 + 100 + 10 + 0.1) Ω , Ukuchaneka oku: ±0.1%;
4. Ibhokisi ye-Capacitor: 0.001 ~ 1μF, ubuncinane benyathelo 0.001μF, ukuchaneka 2%;
5. Ibhokisi ye-inductance: 1～110mH, inyathelo elincinci le-1mH, ukuchaneka kwe-2%;
6. Unikezelo lwamandla okusebenza okuninzi: DC 0～2V unikezelo lwamandla oluhlengahlengiswayo, i-sine wave 50Hz～100kHz;isikwere wave 50Hz
～1kHz;i-frequency iboniswa yi-counter frequency counter 5-digit;
7. I-AC kunye ne-DC ye-galvanometer yedijithali ye-double-purpose: sebenzisa i-voltmeter yokubonisa idijithali: uluhlu luyi-200mV, i-2V;igalelo ungakhetha AC, DC, unbalanced iindlela ezintathu, kukho uvakalelo uhlengahlengiso potentiometer.
8. Xa isixhobo sisetyenziswe njengebhuloho yengalo enye, uluhlu lokulinganisa: 10Ω～1111.1KΩ, inqanaba le-0.1;
9. Xa isixhobo sisetyenziswe njengebhuloho yombane yengalo ezimbini, uluhlu lokulinganisa: 0.01～111.11Ω, 0.2 inqanaba;
10. Uluhlu olusebenzayo lwebhuloho engalinganiyo yi-10Ω～11.111KΩ, kwaye impazamo evumelekileyo yi-0.5%;
11. Kukho iintlobo ezimbini zokumelana nokulinganisa ngaphakathi kwesixhobo: i-RX eyodwa, i-RX kabini, iindidi ezimbini ze-capacitors ezinobuchule obuhlukeneyo kunye nokulahlekelwa okuhlukeneyo;iintlobo ezimbini ze-inductances ezine-inductances ezahlukeneyo kunye namaxabiso ahlukeneyo e-Q;
12. Ibhuloho yombane engalinganiyo ihambelana ne-thermistor sensor yeqondo lokushisa, kwaye i-thermometer yedijithali ye-linear yenzelwe ngesisombululo se-0.01℃;i-thermistor ingasetyenziswa ngokudibeneyo ne-sensor yobushushu yesixhobo somfuniselo woluvo oluqhelekileyo.
13. Uvavanyo lophando: funda ubudlelwane phakathi kwe-capacitance, ilahleko kunye ne-bias voltage;
14. Uvavanyo lophando: funda ubudlelwane phakathi kwe-inductance kunye ne-bias yangoku.
