產(chǎn)品概述
FMQK交直流四端低阻箱是一種多功能可調(diào)電阻設(shè)備，適用于交直流電路中的精密電阻調(diào)節(jié)和電橋橋臂應(yīng)用。該產(chǎn)品采用旋轉(zhuǎn)式開(kāi)關(guān)設(shè)計(jì)，支持多檔位電阻調(diào)節(jié)，能夠滿足教學(xué)、科研及工業(yè)測(cè)試場(chǎng)景的需求。其核心特點(diǎn)是四端測(cè)量結(jié)構(gòu)，可有效減少接觸電阻對(duì)測(cè)量精度的影響，適合低阻值環(huán)境下的高精度實(shí)驗(yàn)。產(chǎn)品設(shè)計(jì)注重穩(wěn)定性和耐用性，接觸部件采用微彈簧壓緊技術(shù)，長(zhǎng)期使用后仍能保持較低的接觸電阻變化。1321
技術(shù)特點(diǎn)
FMQK交直流四端低阻箱提供寬范圍的電阻調(diào)節(jié)能力，典型型號(hào)的示值范圍為0～1111.110Ω，最小步進(jìn)值可達(dá)0.0001Ω，準(zhǔn)確度等級(jí)為0.5%。產(chǎn)品支持多組聯(lián)動(dòng)調(diào)節(jié)，例如二組獨(dú)立比率設(shè)計(jì)（如2×1/10/100Ω），便于自組單/雙臂電橋或電位差計(jì)實(shí)驗(yàn)。電阻元件采用高穩(wěn)定性材料，絕緣支座選用聚風(fēng)塑料，確保良好的電氣隔離性能。此外，設(shè)備內(nèi)置十字分割架結(jié)構(gòu)技術(shù)，優(yōu)化了線對(duì)間的平衡對(duì)稱性，進(jìn)一步提升測(cè)量一致性。42028
應(yīng)用場(chǎng)景
該設(shè)備廣泛應(yīng)用于高校物理與電工實(shí)驗(yàn)、科研單位電學(xué)參數(shù)驗(yàn)證以及工業(yè)領(lǐng)域的電氣檢測(cè)。例如，在教學(xué)中可用于自組交流電橋、暫態(tài)電路分析等實(shí)驗(yàn)；在工業(yè)場(chǎng)景中，可作為校準(zhǔn)數(shù)字歐姆表或測(cè)試低阻器件的輔助工具。其四端設(shè)計(jì)特別適合需要排除引線電阻干擾的場(chǎng)合，如電池內(nèi)阻測(cè)量或微小電阻元件測(cè)試。產(chǎn)品操作簡(jiǎn)便，通過(guò)旋轉(zhuǎn)開(kāi)關(guān)即可快速設(shè)定目標(biāo)阻值，同時(shí)支持多路輸出，適配不同型號(hào)的測(cè)試儀表。61830
使用與維護(hù)
使用前建議旋轉(zhuǎn)開(kāi)關(guān)數(shù)次以確保接觸穩(wěn)定，連接導(dǎo)線需牢固且不超過(guò)標(biāo)稱功率（如0.25W）。存儲(chǔ)環(huán)境建議為溫度10～30℃、濕度低于75%的無(wú)腐蝕性氣體場(chǎng)所。設(shè)備配備說(shuō)明書(shū)和合格證，用戶需避免錯(cuò)誤接線導(dǎo)致?lián)p壞。長(zhǎng)期不使用時(shí)，應(yīng)定期通電檢測(cè)以保持性能。1711
Product Overview
The FMQK AC/DC Four-Terminal Low Resistance Box is a versatile adjustable resistor device designed for precise resistance regulation in both AC and DC circuits, as well as for bridge arm applications. Featuring a rotary switch mechanism, it supports multi-range resistance adjustment, catering to educational, research, and industrial testing needs. Its four-terminal measurement structure minimizes contact resistance interference, making it ideal for high-precision experiments in low-resistance environments. The product emphasizes stability and durability, with contact components utilizing micro-spring compression technology to maintain consistent performance over time.1321
Technical Features
With a typical resistance range of 0～1111.110Ω and a minimal step increment of 0.0001Ω, the FMQK achieves an accuracy class of 0.5%. It offers flexible configurations such as dual independent ratio settings (e.g., 2×1/10/100Ω), facilitating experiments like self-assembled single/double bridges or potentiometers. High-stability materials are used for resistive elements, while insulated supports made of polypropylene ensure excellent electrical isolation. The cross-segmentation frame technology enhances balance between wire pairs, improving measurement consistency.42028
Applications
This device is widely employed in university physics and electrical engineering labs, research institutes for parameter validation, and industrial electrical testing. For instance, it serves in teaching experiments like AC bridge assembly and transient circuit analysis, or in industrial settings for calibrating digital ohmmeters and testing low-resistance components. The four-terminal design is particularly effective in scenarios requiring elimination of lead resistance interference, such as battery internal resistance measurement. Its user-friendly rotary switches enable quick setup, and multi-channel output compatibility adapts to various test instruments.61830
Operation & Maintenance
Prior to use, rotate switches several times to stabilize contacts, and ensure connections are secure without exceeding rated power (e.g., 0.25W). Store in environments with 10～30℃ temperature and <75% humidity, free from corrosive gases. The package includes an instruction manual and certification, and users should avoid incorrect wiring to prevent damage. Periodic performance checks during prolonged storage are recommended.1711
