功能特點(diǎn)
FM-02采用直觀的面板布局，所有比例臂電阻和接線端子均清晰標(biāo)注，便于快速搭建單橋或雙橋測(cè)量電路。儀器支持寬范圍電阻測(cè)量，用戶可通過調(diào)節(jié)標(biāo)準(zhǔn)電阻箱實(shí)現(xiàn)精密微調(diào)，配合內(nèi)置檢流計(jì)實(shí)時(shí)監(jiān)測(cè)平衡狀態(tài)，確保數(shù)據(jù)準(zhǔn)確性。此外，其穩(wěn)定的電源輸出和模塊化設(shè)計(jì)，可有效降低外部干擾，適合演示惠斯登電橋原理及凱爾文電橋的實(shí)際應(yīng)用。2612
教學(xué)應(yīng)用價(jià)值
該演示儀通過實(shí)物操作幫助學(xué)生理解電橋平衡條件與電阻測(cè)量原理，尤其適用于電磁學(xué)基礎(chǔ)課程和電工實(shí)驗(yàn)。其雙橋模式能直觀展示低阻測(cè)量的關(guān)鍵技術(shù)，如四線法消除接觸電阻影響。儀器結(jié)構(gòu)緊湊，操作簡(jiǎn)單，可重復(fù)性強(qiáng)，是物理與工程學(xué)科實(shí)驗(yàn)教學(xué)的理想工具。727
設(shè)計(jì)優(yōu)勢(shì)
FM02采用耐用材質(zhì)與人性化設(shè)計(jì)，如防滑底座和可拆卸接線柱，兼顧安全性與便捷性。無外接電源依賴的設(shè)計(jì)（部分型號(hào)支持電池供電）使其適用于野外或無市電環(huán)境。整體設(shè)計(jì)注重教學(xué)演示效果，例如通過彩色標(biāo)識(shí)區(qū)分不同功能區(qū)域，降低學(xué)習(xí)門檻。428
English Introduction
Product Overview
The FM02 Single/Dual DC Bridge Demonstrator (FM-02) is an educational instrument designed for electrical measurement experiments in universities, research institutes, and industrial laboratories. It supports both Wheatstone bridge (single bridge) and Kelvin bridge (double bridge) configurations to measure medium and low-range DC resistances with precision. The built-in galvanometer, standard resistors (0.01Ω, 0.1Ω, 1Ω), and adjustable resistance box (0～10×1/10/100/1000Ω) simplify circuit balancing, while integrated stable power sources enhance operational efficiency. 13
Key Features
With a user-friendly interface, the FM-02 allows quick setup of bridge circuits via clearly labeled terminals and ratio arms. Its wide measurement range and fine-tuning capability through the resistance box ensure accurate results, supported by real-time galvanometer feedback. The modular design minimizes external interference, making it suitable for demonstrating fundamental principles of resistance measurement. 612
Educational Benefits
Ideal for physics and engineering courses, this demonstrator visually explains bridge equilibrium conditions and low-resistance measurement techniques (e.g., four-wire method). Hands-on operation reinforces theoretical knowledge, while repeatable experiments cater to diverse learning scenarios. Compact and portable, it adapts to classroom or field environments. 727
Design Highlights
Durable construction with non-slip base and detachable terminals ensures safety and longevity. Optional battery-powered models expand usage flexibility in off-grid settings. Color-coded functional zones and intuitive layout reduce complexity, enabling effortless student engagement. 428
