LEEM-23 Multifunctional Bridge Experiment

Main technical parameters
1. Choj caj npab tsis kam R1: Configure ib txheej ntawm precision resistances: 10Ω, 100Ω, 1000Ω, 10kΩ, uas yog hloov dua siab tshiab los ntawm luv-circuit plug kev twb kev txuas, thiab cov kuj raug yog ± 0.1%;
2. Choj caj npab tsis kam R2: Teeb tsa cov thawv tiv thaiv: 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 nruab rau hauv tib lub txheej ob txheej hloov mus, thiab cov kev hloov pauv ib txhij: 10 × (1000 + 100 + 10 + 1 + 0.1) Ω , tsis kam
Qhov tseeb yog: ± 0.1%, ± 0.2%, ± 1%, ± 2%, ± 5%;
4. Cov qauv kev ua haujlwm RN: Cov nqi tiv thaiv yog: 10Ω, 1Ω, 0.1Ω, 0.01Ω, thiab cov ntsiab lus tsis kam tiv taus
Lwm yam tshaj li: ± 0.1%, ± 0.1%, ± 0.2%, ± 0.5%, tuaj yeem txuas nrog sab nraud;
5. Built-in kuj yuav 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 tuaj yeem siv los ntsuas tus choj lossis kuaj seb tus choj puas ua haujlwm zoo.
6. Digital galvanometer: siv 4 thiab ib nrab digital zaub voltmeter: ntau yam yog 200mV, 2V.Cov lus pom tseeb ntawm cov galvanometer yog: (0.1% ntau ± 2 lo lus).Galvanometer tuaj yeem txuas nrog sab nraud;
7. Multi-function fais fab mov: 0 ~ 2V adjustable fais fab mov, 3V, 9V fais fab mov.
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. Thaum teeb tsa tus choj tsis sib haum, lub ntsuas yuav tsum tau nruab nrog lub ntsuas hluav taws xob los yog ntsuas kub.
12. Txhua yam ntawm cov txuas hluav taws xob zoo sib xws tuaj yeem hloov kho.
