設(shè)備核心由優(yōu)質(zhì)合金電阻絲與絕緣基板構(gòu)成，通過精密加工工藝確保阻值穩(wěn)定性，有效降低環(huán)境溫度對(duì)測量結(jié)果的影響。面板布局采用人性化設(shè)計(jì)，每個(gè)檔位均配備獨(dú)立開關(guān)和清晰標(biāo)識(shí)，支持0.1Ω至11111.1Ω的寬范圍調(diào)節(jié)，最小步進(jìn)值為0.1Ω。內(nèi)部采用多層隔離技術(shù)，有效減少相鄰電阻間的電磁干擾，保障測量數(shù)據(jù)的可靠性。

ZX25a適用于電子元器件性能測試、電路板調(diào)試、傳感器校準(zhǔn)等場景，也可作為高校電工學(xué)、電子技術(shù)課程的實(shí)驗(yàn)教具。設(shè)備外殼采用工程塑料與金屬復(fù)合材質(zhì)，具備良好的機(jī)械強(qiáng)度與散熱性能，旋鈕部分配置防滑紋路提升操作手感。使用過程中建議搭配數(shù)字萬用表進(jìn)行實(shí)時(shí)監(jiān)測，以獲得更精準(zhǔn)的調(diào)節(jié)效果。

‌English Introduction‌
The ZX25a Switch-Type DC Resistance Box is a precision-engineered device for circuit parameter adjustment, designed for laboratory testing, educational demonstrations, and industrial measurement applications. Featuring a modular structure with rotary switches, it enables rapid resistance value selection from 0.1Ω to 11111.1Ω, providing flexible configuration for diverse operational requirements.

Constructed with premium alloy resistance wires and insulated substrates, the device maintains stable resistance values through advanced manufacturing processes, significantly reducing temperature-induced measurement deviations. The intuitive front panel design incorporates individually labeled switches for each decade, while multilayer shielding technology minimizes electromagnetic interference between adjacent resistors.

Ideal for electronic component testing, PCB debugging, and sensor calibration, this unit also serves as an effective teaching tool for electrical engineering courses. The hybrid casing combines engineering plastics with metal reinforcements, delivering enhanced durability and thermal management. Ergonomically designed knobs with anti-slip grooves ensure precise control during operation. For optimal performance, real-time monitoring with digital multimeters is recommended when performing critical measurements.
