本產(chǎn)品核心部件采用高穩(wěn)定性合金材料制作，配合精密機(jī)械加工工藝，確保電阻接觸點(diǎn)長期使用后仍能保持穩(wěn)定性能。電阻調(diào)節(jié)范圍覆蓋0.1Ω至10kΩ區(qū)間，支持最小0.1Ω的步進(jìn)精度調(diào)節(jié)。旋轉(zhuǎn)開關(guān)采用雙觸點(diǎn)彈性結(jié)構(gòu)設(shè)計(jì)，有效降低接觸電阻波動，同時(shí)具備清晰的檔位定位手感，方便實(shí)驗(yàn)人員快速準(zhǔn)確設(shè)定參數(shù)。
在電路設(shè)計(jì)方面，采用分層式絕緣基板架構(gòu)，各檔位電阻元件間保持合理的安全間距，避免因環(huán)境濕度變化引發(fā)漏電風(fēng)險(xiǎn)。外殼選用工程級阻燃材料，表面經(jīng)過抗氧化處理，適合在-10℃至+40℃環(huán)境溫度下穩(wěn)定工作。接口配置標(biāo)準(zhǔn)香蕉插孔，兼容多數(shù)實(shí)驗(yàn)室測試線纜。
該裝置特別適用于電子電路基礎(chǔ)實(shí)驗(yàn)教學(xué)、電子元器件特性測試、儀器儀表校準(zhǔn)等場景。操作面板布局符合人體工程學(xué)原理，各檔位標(biāo)識采用激光蝕刻工藝，確保長期使用后仍能保持清晰可辨。維護(hù)時(shí)可單獨(dú)拆卸各檔位組件進(jìn)行清潔保養(yǎng)，有效延長設(shè)備使用壽命。
【English Version】
The ZX21c Rotary Resistance Box is a precision adjustable device developed for laboratory experiments, educational demonstrations, and electronic equipment calibration. Featuring a modular design with multiple independent rotary switches, it provides flexible resistance adjustment capability within DC and low-frequency circuit applications.
Constructed with high-stability alloy components and precision machining techniques, this device maintains consistent performance through extended usage. The resistance adjustment range spans from 0.1Ω to 10kΩ with 0.1Ω minimum incremental steps. The dual-contact elastic structure in rotary switches minimizes contact resistance variation while delivering precise tactile feedback for accurate parameter setting.
The circuit architecture incorporates layered insulation substrates, ensuring safe clearance between resistance elements to prevent leakage current under varying humidity conditions. The flame-retardant engineering plastic enclosure with oxidation-resistant surface treatment guarantees reliable operation within -10℃ to +40℃ temperature range. Standard banana jack interfaces ensure compatibility with most laboratory test leads.
Ideal for fundamental circuit experiments, component characteristic analysis, and instrument calibration, the device features an ergonomic control panel with laser-etched scale markings for lasting legibility. Maintenance-friendly modular components allow individual disassembly for cleaning and servicing, significantly extending product service life. The optimized mechanical structure balances operational sensitivity with durability, making it a practical tool for repeated experimental use.
