ZX2N1交直流四端低阻箱
ZX2N1交直流四端低阻箱產(chǎn)品概述
ZX2N1交直流四端低阻箱是一種可調(diào)節(jié)電阻值并顯示阻值的精密測量設(shè)備，適用于交直流電路中的阻抗調(diào)節(jié)與橋臂元件應(yīng)用。該設(shè)備采用四端設(shè)計，有效減少接觸電阻對測量結(jié)果的影響，適合工廠、學(xué)校及實驗室等場景下的電氣實驗與儀器校準(zhǔn)。其阻值調(diào)節(jié)范圍為0～11.0Ω，最小步進(jìn)0.1Ω，額定功率0.5W，能夠滿足中低阻值的精確調(diào)控需求。設(shè)備開關(guān)結(jié)構(gòu)采用微彈簧壓緊技術(shù)，長期使用后接觸電阻穩(wěn)定性良好，絕緣性能優(yōu)異。148
Technical Specifications of ZX2N1 AC/DC Four-Terminal Low-Resistance Box
The ZX2N1 is a compact resistance box supporting both AC and DC circuits, with a resistance range of 0～11.0Ω and 0.1Ω minimum increment. Its four-terminal Kelvin connection design minimizes lead resistance interference, making it suitable for precision measurements in electrical engineering experiments and equipment calibration. The device features durable spring-loaded contacts that maintain stable performance over extended use, while high-insulation polymer materials ensure operational safety. The rated power is 0.5W with accuracy maintained within specified parameters under normal operating conditions.257
產(chǎn)品結(jié)構(gòu)與設(shè)計特點
該設(shè)備采用旋轉(zhuǎn)式十進(jìn)盤調(diào)節(jié)結(jié)構(gòu)，操作簡便直觀，可直接讀取阻值。電阻支座選用高絕緣聚風(fēng)塑料材質(zhì)，兼具機(jī)械強(qiáng)度與電氣安全性。內(nèi)部接觸環(huán)、接觸片及電刷通過微彈簧保持恒定壓力，有效降低長期使用導(dǎo)致的接觸電阻變化。典型應(yīng)用場景包括電橋測量、電流限制以及教學(xué)演示等，其四端設(shè)計特別適合需要消除引線電阻影響的精密測量場合。設(shè)備外形尺寸適中，便于實驗室臺面部署與移動。4618
Application Scenarios and Functional Advantages
Ideal for educational demonstrations and industrial testing, this unit provides reliable resistance simulation in circuit debugging and calibration workflows. The clear numerical display allows quick verification of set values, and the dual AC/DC compatibility extends its utility across diverse electrical testing environments. Compared to sliding rheostats, it offers discrete but precisely quantifiable resistance adjustments, with enhanced stability for fixed-value applications. The robust construction withstands frequent adjustments while maintaining consistent performance within specified temperature and humidity ranges.81012
使用注意事項與維護(hù)建議
使用前建議旋轉(zhuǎn)各組旋鈕使觸點充分接觸，以獲得穩(wěn)定阻值輸出。工作時需確保不超過標(biāo)稱功率，避免過熱損傷。存儲時應(yīng)置于10-30℃干燥環(huán)境中，遠(yuǎn)離腐蝕性氣體。定期清潔觸點可延長使用壽命，若需微小阻值變化，建議將接線端接入"0"與小阻值端子以減少引線誤差。長期停用后重新啟用時，建議先進(jìn)行多次旋鈕操作恢復(fù)接觸性能。81725
