Taw qhia

1. Choj caj npab kuj R1: 1Ω, 10Ω, 100Ω, 1000Ω, 10kΩ, 100kΩ, 1MΩ.
Qhov tseeb ± 0.1%;
2. Choj caj npab tsis kam R2: teeb tsa lub thawv tiv thaiv: 10kΩ + 10 × (1000 + 100 + 10 + 1) Ω, qhov tseeb ± 0.1%;
3. Choj caj npab tsis kam R3: Teeb tsa ob pawg ntawm synchronous resistance thawv R3a, R3b, uas tau nruab nrog rau hauv tib ob txheej hloov hloov mus, thiab cov kev hloov pauv hloov synchronously: 10 × (1000 + 100 + 10 + 1 + 0.1) Ω, qhov tseeb yog: ± 0.1%;
4. Capacitor box: 0.001 ~ 1μF, yam tsawg kawg nkaus kauj ruam 0.001μF, raug 2%;
5. Inductance box: 1～110mH, yam tsawg kawg nkaus kauj ruam 1mH, raug 2%;
6. Multi-function fais fab mov: DC 0 ~ 2V adjustable fais fab mov, sine yoj 50Hz ~ 100kHz;square wave 50Hz
～1kHz;qhov zaus yog tso tawm los ntawm 5-tus lej zaus ntsuas;
7. AC thiab DC dual-purpose digital galvanometer: siv cov duab digital voltmeter: ntau yam yog 200mV, 2V;input tuaj yeem xaiv AC, DC, tsis sib npaug peb hom, muaj qhov hloov pauv hloov pauv potentiometer.
8. Thaum cov cuab yeej siv los ua ib qho kev sib txuas ntawm caj npab, qhov ntsuas ntau: 10Ω～1111.1KΩ, 0.1 qib;
9. Thaum cov cuab yeej siv los ua ob sab caj npab hluav taws xob, qhov ntsuas ntau: 0.01 ~ 111.11Ω, 0.2 qib;
10. Qhov ua tau zoo ntawm tus choj tsis sib npaug yog 10Ω～11.111KΩ, thiab qhov kev tso cai yuam kev yog 0.5%;
11. Muaj ob hom kev ntsuas kev tiv thaiv nyob rau hauv lub ntsuas: RX ib leeg, RX ob npaug, ob hom capacitors uas muaj peev xwm sib txawv thiab sib txawv;ob hom inductance nrog sib txawv inductances thiab txawv Q tus nqi;
12. Tus choj hluav taws xob tsis sib haum yog sib npaug nrog lub ntsuas kub ntawm lub thermistor, thiab cov ntsuas kub ntawm cov kab hluav taws xob yog tsim los nrog kev daws teeb meem ntawm 0.01 ℃;lub thermistor tuaj yeem siv ua ke nrog qhov ntsuas kub ntawm qhov ntsuas ntsuas ntsuas ntsuas ntsuas.
13. Kev tshawb nrhiav kev sim: kawm txog kev sib raug zoo ntawm qhov muaj peev xwm, qhov poob thiab qhov tsis zoo voltage;
14. Kev sim tshawb fawb: kawm txog kev sib raug zoo ntawm inductance thiab bias tam sim no.
