QJ32 DC Single/Double Arm Bridge Product Introduction (English)
The QJ32 DC Single/Double Arm Bridge is a portable precision instrument based on Kelvin circuit design, integrating both single-arm and double-arm bridge functionalities. It performs high-accuracy measurements for DC low-resistance (0.01μΩ~1111.10Ω) with built-in null detector and power supply, suitable for laboratories, industrial sites, and field operations. Key features include: Manganin alloy resistors for stable performance, 7-range selective calibration, 0.00001Ω resolution, and an intelligent sensitivity knob to optimize voltage output. Applications span from material resistivity testing (metal rods/cables) to equipment inspection (transformer windings, contact resistance). The compact design (410×260×150mm) with integrated electronic galvanometer ensures efficient on-site measurements, making it a versatile tool for power maintenance and manufacturing sectors.6720
技術(shù)特性補充說明
儀器采用分體式端鈕設(shè)計,單橋模式時通過端鈕5/6接入被測電阻,雙橋模式則使用7/8端鈕配合標(biāo)準(zhǔn)電阻實現(xiàn)高精度低阻測量。內(nèi)置1.5V干電池與9V疊層電池供電,支持-15℃~45℃環(huán)境工作。面板布局直觀,含粗/細(xì)調(diào)按鈕分級調(diào)節(jié),避免過載風(fēng)險,同時提供外接檢流計接口以滿足特殊場景需求。62127
Additional Technical Notes
The instrument adopts split-terminal design: terminals 5/6 for single-arm mode while 7/8 for double-arm mode with standard resistors. Powered by 1.5V dry cells and 9V laminated batteries, it operates in -15℃~45℃ environments. The panel features coarse/fine adjustment buttons for gradient control and external galvanometer ports for extended applications. The modular structure with silver-copper composite contacts enhances durability.212226
