英文介紹
The FMQ-10000 Universal Resistance Box is a precision laboratory instrument featuring dual-channel resistance output with independent/parallel operation modes. Its innovative design incorporates 7-decade rotary switches (2×100Ω fixed + 5×0.01-100Ω adjustable) allowing resistance simulation from 0.01Ω to 11.11kΩ. The nickel-chromium alloy resistors with ceramic substrates ensure ±0.05% accuracy under 25±5℃ ambient temperature.
Ideal for physics education, this unit enables hands-on experiments including Wheatstone bridge construction, thermistor characterization, and circuit impedance matching. The dust-proof aluminum alloy case (260×180×120mm) provides mechanical protection while the gold-plated contacts minimize contact resistance. Standard 4mm safety terminals support both DC measurements and low-frequency AC applications up to 1kHz.
Industrial users benefit from its rapid response in PLC I/O testing and transducer calibration. The front-panel LED indicators clearly display active ranges, while the ergonomic knobs allow precise adjustment even with protective gloves. Compatible with most bench-top multimeters and data acquisition systems through standard BNC or banana jack interfaces. 31519
