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
產(chǎn)品技術(shù)特點(diǎn)
該電阻箱采用彈簧微調(diào)開關(guān)結(jié)構(gòu)，經(jīng)1萬(wàn)次操作后接觸變差仍小于0.2mΩ，確保長(zhǎng)期使用的穩(wěn)定性。時(shí)間常數(shù)控制在10^-8秒量級(jí)（如×1000Ω檔為50×10^-8秒），頻率特性優(yōu)異，在20kHz音頻范圍內(nèi)因頻率引起的變差小于0.1%，擴(kuò)展至100kHz時(shí)變差仍低于0.5%。各檔位電阻采用獨(dú)立繞制工藝，配合瓷管骨架保障溫度系數(shù)一致性，在15~25℃標(biāo)準(zhǔn)溫度范圍內(nèi)可實(shí)現(xiàn)標(biāo)稱精度。面板布局符合人體工程學(xué)，接地端子設(shè)計(jì)完善屏蔽系統(tǒng)，旋鈕阻尼適中且檔位清晰。產(chǎn)品隨附完整使用說(shuō)明書，提供電阻值-電流對(duì)應(yīng)關(guān)系表（如0.01Ω檔允許0.7A）等實(shí)用數(shù)據(jù)，指導(dǎo)用戶合理配置測(cè)量參數(shù)。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
