【中文版】
FMT500普通型十進(jìn)電感箱是一款專為電子電路實(shí)驗(yàn)、教學(xué)演示及工業(yè)測(cè)量設(shè)計(jì)的精密調(diào)節(jié)設(shè)備。該產(chǎn)品采用模塊化十進(jìn)制步進(jìn)結(jié)構(gòu)，通過多檔位組合實(shí)現(xiàn)電感值的靈活調(diào)節(jié)，可滿足0.1mH至100H范圍內(nèi)的電感參數(shù)模擬需求，適用于濾波器調(diào)試、諧振電路搭建及電子元件特性分析等多種應(yīng)用場(chǎng)景。
設(shè)備采用優(yōu)質(zhì)合金材料繞制電感線圈，配合特殊工藝處理，有效降低分布電容對(duì)測(cè)量精度的影響。獨(dú)特的機(jī)械式旋鈕切換系統(tǒng)提供清晰的檔位觸感，每個(gè)十進(jìn)檔位均設(shè)有獨(dú)立調(diào)節(jié)單元，避免信號(hào)串?dāng)_。整體箱體采用金屬屏蔽結(jié)構(gòu)設(shè)計(jì)，可大幅減少外部電磁干擾，確保實(shí)驗(yàn)數(shù)據(jù)的穩(wěn)定性。
在功能設(shè)計(jì)上，F(xiàn)MT500支持雙向電感值調(diào)節(jié)功能，正向/反向旋轉(zhuǎn)旋鈕均可實(shí)現(xiàn)參數(shù)微調(diào)。全量程范圍內(nèi)電感值的線性偏差控制在±1%以內(nèi)，溫度漂移系數(shù)小于0.05%/℃。特別設(shè)計(jì)的彈性觸點(diǎn)結(jié)構(gòu)經(jīng)10萬次切換測(cè)試仍保持良好接觸性能，有效延長(zhǎng)設(shè)備使用壽命。
產(chǎn)品配備標(biāo)準(zhǔn)化接線端子，兼容香蕉插頭和鱷魚夾等多種連接方式。底部防滑腳墊與側(cè)面握持凹槽的人性化設(shè)計(jì)，既保證操作穩(wěn)定性又便于實(shí)驗(yàn)室移動(dòng)使用。適用于高校電子實(shí)驗(yàn)室、電子元件生產(chǎn)企業(yè)以及無線電愛好者工作間等場(chǎng)景，是電路調(diào)試和教學(xué)演示的理想輔助工具。
【English Version】
The FMT500 Standard Decimal Inductance Box is a precision adjustment instrument designed for electronic circuit experiments, educational demonstrations, and industrial measurement applications. Featuring a modular decimal stepping structure, this device enables flexible inductance value adjustment through multi-range combinations, covering a wide range from 0.1mH to 100H. It is ideally suited for various applications including filter debugging, resonant circuit construction, and electronic component characteristic analysis.
Constructed with high-quality alloy winding coils and specialized processing techniques, the device effectively minimizes the impact of distributed capacitance on measurement accuracy. The unique mechanical rotary switching system provides clear tactile feedback for each range selection, with independent adjustment units for every decimal range to prevent signal crosstalk. The metal-shielded enclosure significantly reduces external electromagnetic interference, ensuring stable experimental data.
The FMT500 offers bidirectional inductance adjustment through both clockwise and counterclockwise rotation of the control knob. Linear deviation across the full range is maintained within ±1%, with temperature drift coefficient below 0.05%/℃. The specially designed elastic contact structure has undergone 100,000 switching cycle tests while maintaining reliable connection performance, ensuring extended service life.
Equipped with standard binding posts compatible with banana plugs and alligator clips, the device combines operational stability with laboratory mobility through its non-slip base pads and ergonomic side grips. Suitable for university electronics labs, electronic component manufacturers, and radio enthusiasts workshops, it serves as an excellent auxiliary tool for circuit debugging and educational demonstrations. The intuitive interface design allows quick mastery of operation methods, supporting efficient completion of diverse experimental tasks.
