ZX-32 AC/DC Resistance Box Product Introduction (English)
The ZX-32 AC/DC Resistance Box is a precision adjustable resistance instrument designed for electrical measurement applications in laboratories, industrial facilities, and educational institutions. Featuring resistance coils wound with high-quality manganin wire, this device provides stable and reliable resistance values ranging from 0 to 11111.10Ω with a minimum increment of 0.01Ω and 0.05% accuracy. It functions effectively as a variable standard resistor in both AC circuits (0-10kHz) and DC circuits, or serves as bridge arms in higher-frequency bridge measurements. The rotary decade switch system incorporates six interconnected switches for intuitive six-digit resistance adjustment. With a rated power of 0.25W, each resistance range clearly indicates permissible current values (e.g. 0.015A for 1000Ω range) to ensure operational safety. The metal-shielded enclosure effectively minimizes external interference while maintaining robust insulation (withstanding 2000V AC for 1 minute between circuits and shield). Operating reliably within +5~+45℃ temperature and ≤80% humidity conditions, the device exhibits low zero resistance (30±5mΩ) and minimal zero inductance (<2μH). Its compact dimensions (260×200×180mm) and 4kg weight facilitate portability and installation. The product is particularly suitable for precision experiments, equipment calibration, and electrical parameter verification scenarios requiring adjustable resistance standards. 92023
产品技术特点
该电阻箱采用弹簧微调开关结构，经1万次操作后接触变差仍小于0.2mΩ，确保长期使用的稳定性。时间常数控制在10^-8秒量级（如×1000Ω档为50×10^-8秒），频率特性优异，在20kHz音频范围内因频率引起的变差小于0.1%，扩展至100kHz时变差仍低于0.5%。各档位电阻采用独立绕制工艺，配合瓷管骨架保障温度系数一致性，在15~25℃标准温度范围内可实现标称精度。面板布局符合人体工程学，接地端子设计完善屏蔽系统，旋钮阻尼适中且档位清晰。产品随附完整使用说明书，提供电阻值-电流对应关系表（如0.01Ω档允许0.7A）等实用数据，指导用户合理配置测量参数。51725
Application Scenarios
This resistance box demonstrates versatile applications across multiple fields. In educational settings, it serves as fundamental equipment for physics and electrical engineering experiments involving Ohm s law verification, bridge circuit construction, and sensor characteristic testing. Industrial users employ it for calibrating resistance-based instruments such as multimeters and LCR meters, or simulating load conditions during equipment debugging. Research laboratories utilize its precise resistance adjustment capability for material conductivity studies and electronic component parameter matching. The product s wide frequency response makes it particularly valuable in audio equipment testing and communication circuit analysis scenarios. When used as bridge arms, its low time constant characteristics contribute to improving measurement system response speed and accuracy. 121527
