FMOR Test Resistance Board Product Introduction (English)

The FMOR test resistance board is a precision instrument component designed for resistance measurement experiments, widely used in educational and research settings such as factories, schools, and laboratories. Featuring 21 adjustable resistance ranges (20Ω to 5.6MΩ) including 5 blind-test positions, it accommodates various measurement accuracy requirements. The product s streamlined structure facilitates easy installation and modular combination, while its built-in protection mechanism safeguards galvanometers from strong current impacts. The dynamic zero-verification function enhances balancing sensitivity significantly. Compatible with multiple operation modes including calibration, measurement, and charge/discharge circuit switching, it demonstrates broad adaptability with various bridge instruments. The sealed switch design ensures minimal contact pressure, extended lifespan, and reduced voltage variation for stable measurements. Covering medium resistance ranges, it is particularly suitable for precision resistance adjustment and known-value applications in DC circuits. 1514
