LEEM-23 Kev Sim Choj Ntau Yam

Cov kev tsis tseem ceeb
1. Choj caj npab tsis kam R1: Kho ib pawg ntawm cov kev tiv thaiv precision: 10Ω, 100Ω, 1000Ω, 10kΩ, uas tau hloov pauv los ntawm kev sib txuas luv luv, thiab qhov tseeb tsis kam yog ± 0.1%;
2. Choj caj npab tsis kam R2: Kho ib pawg ntawm cov thawv tsis kam: 10 × (1000 + 100 + 10 + 1) Ω, qhov tseeb tsis kam yog: ± 0.1%, ± 0.2%, ± 1%, ± 2%;
3. Choj caj npab tsis kam R3: Teeb tsa ob pawg ntawm cov thawv tsis kam R3a, R3b, uas tau teeb tsa sab hauv ntawm tib lub hloov pauv ob txheej, thiab qhov tsis kam hloov pauv tib lub sijhawm: 10 × (1000 + 100 + 10 + 1 + 0.1) Ω, tsis kam
Qhov tseeb yog: ± 0.1%, ± 0.2%, ± 1%, ± 2%, ± 5%;
4. Tus qauv tsis kam RN: Cov nqi tsis kam yog: 10Ω, 1Ω, 0.1Ω, 0.01Ω, thiab cov ntsiab lus raug tsis kam
Lwm yam tshaj li: ±0.1%, ±0.1%, ±0.2%, ±0.5%, tuaj yeem txuas nrog sab nraud;
5. Kev tiv thaiv ua ke uas yuav tsum ntsuas: Rx ib leeg: 1kΩ, 0.25W, tsis paub meej: 0.1%; Rx ob npaug: 0.2 ohm, 0.25W, tsis paub meej: 0.2%. Ob lub resistors no siv tau los calibrate tus choj lossis sim seb tus choj puas ua haujlwm zoo.
6. Digital galvanometer: siv 4 thiab ib nrab digital zaub voltmeter: ntau yam yog 200mV, 2V. Qhov tseeb ntawm cov zaub ntawm digital galvanometer yog: (0.1% ntau yam ± 2 lo lus). Galvanometer tuaj yeem txuas nrog sab nraud;
7. Muaj ntau lub zog fais fab: 0 ~ 2V kho tau fais fab, 3V, 9V fais fab.
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. Thaum teeb tsa tus choj tsis sib npaug, lub cuab yeej yuav tsum tau nruab nrog lub sensor tiv thaiv lossis lub cuab yeej tswj kub.
12. Txhua yam choj fais fab zoo sib xws tuaj yeem hloov kho tau.
