FMQJ-5 Multifunctional Teaching Bridge (English Version)
The FMQJ-5 Multifunctional Teaching Bridge is an innovative measurement instrument specifically designed for electronic engineering education and fundamental laboratory applications. Ideal for university and vocational college laboratories, this device combines classical bridge measurement principles with modern electronic technologies to deliver intuitive operation and reliable data acquisition, facilitating comprehensive understanding of circuit parameter measurement methodologies.
Featuring a modular design, the instrument integrates three essential measurement functions: resistance, capacitance, and inductance. It supports both manual and automatic adjustment modes, equipped with a dual-display system comprising an analog meter and digital LCD screen. This hybrid display preserves the operational authenticity of traditional bridges while ensuring measurement accuracy, with ranges covering common educational experiment requirements. The minimum resolution reaches 0.1Ω (resistance), 1nF (capacitance), and 0.1mH (inductance).
Specialized teaching-oriented features include built-in typical circuit models for demonstrating parameter variations, a data hold function for experiment recording, and open-access terminals for component expansion. The ergonomic panel layout with color-coded terminals enhances operational clarity, while the composite construction of engineering plastics and metal components ensures measurement stability. Specially treated contact points minimize connection resistance for improved accuracy.
In laboratory settings, this device supports essential experiments such as circuit characteristic analysis, component parameter measurement, and bridge circuit principle verification. Its progressive experiment system cultivates students capabilities in comparative measurement and error analysis. Compatible with mainstream experiment platforms, the included teaching manual provides over a dozen structured experiment protocols, enabling step-by-step learning from basic concepts to comprehensive applications.
