Kev Taw Qhia

1. Choj caj npab tsis kam R1: 1Ω, 10Ω, 100Ω, 1000Ω, 10kΩ, 100kΩ, 1MΩ.
Qhov tseeb ± 0.1%;
2. Choj caj npab tsis kam R2: teeb tsa ib pawg ntawm cov thawv tsis kam: 10kΩ + 10 × (1000 + 100 + 10 + 1) Ω, qhov tseeb ± 0.1%;
3. Choj caj npab tsis kam R3: Kho ob pawg ntawm cov thawv tsis kam sib xws R3a, R3b, uas tau teeb tsa sab hauv ntawm tib lub hloov pauv ob txheej, thiab qhov tsis kam hloov pauv sib xws: 10 × (1000 + 100 + 10 + 1 + 0.1) Ω, Qhov tseeb yog: ± 0.1%;
4. Lub thawv capacitor: 0.001 ~ 1μF, kauj ruam tsawg kawg nkaus 0.001μF, qhov tseeb 2%;
5. Lub thawv inductance: 1 ~ 110mH, kauj ruam tsawg kawg nkaus 1mH, qhov tseeb 2%;
6. Muaj ntau lub zog fais fab: DC 0 ~ 2V kho tau lub zog fais fab, sine wave 50Hz ~ 100kHz; square wave 50Hz
～1kHz; qhov zaus yog tso tawm los ntawm 5-tus lej zaus suav;
7. AC thiab DC ob lub hom phiaj digital galvanometer: siv cov zaub digital voltmeter: ntau yog 200mV, 2V; cov tswv yim tuaj yeem xaiv AC, DC, tsis sib npaug peb hom, muaj lub potentiometer hloov kho qhov rhiab heev.
8. Thaum siv lub cuab yeej ua ib lub choj ib sab caj npab, qhov ntsuas ntau yam: 10Ω ~ 1111.1KΩ, 0.1 theem;
9. Thaum siv lub cuab yeej ua tus choj hluav taws xob ob sab caj npab, qhov ntsuas ntau yam: 0.01 ~ 111.11Ω, 0.2 theem;
10. Qhov ntau yam zoo ntawm tus choj tsis sib npaug yog 10Ω ~ 11.111KΩ, thiab qhov yuam kev tso cai yog 0.5%;
11. Muaj ob hom kev ntsuas tsis kam hauv lub cuab yeej: RX ib leeg, RX ob npaug, ob hom capacitors nrog ntau lub peev xwm thiab ntau qhov poob; ob hom inductances nrog ntau yam inductances thiab ntau yam Q tus nqi;
12. Lub choj hluav taws xob tsis sib npaug tau phim nrog lub ntsuas kub thermistor, thiab lub ntsuas kub digital linear tau tsim nrog qhov kev daws teeb meem ntawm 0.01 ℃; lub thermistor tuaj yeem siv ua ke nrog lub ntsuas kub ntawm cov cuab yeej sim sensor ib txwm muaj.
13. Kev sim tshawb fawb: kawm txog kev sib raug zoo ntawm capacitance, poob thiab bias voltage;
14. Kev sim tshawb fawb: kawm txog kev sib raug zoo ntawm inductance thiab bias tam sim no.
