產(chǎn)品技術(shù)特點
FM-QC1具備三項核心功能：一是按E6序列標稱值設(shè)計，符合常規(guī)電路測試需求；二是支持損耗角正切值（tgδ）調(diào)節(jié)功能，可模擬不同介質(zhì)特性的電容；三是設(shè)有盲測檔位，適用于教學考核或隱蔽測試場景。其結(jié)構(gòu)設(shè)計注重實用性，所有電氣部件均安裝在屏蔽機箱內(nèi)，面板配備標準端鈕接口（1/2端鈕和屏蔽接地端鈕0），支持二端或三端接入方式。產(chǎn)品工作溫度范圍為+10℃至+35℃，適應常規(guī)實驗室環(huán)境。18
FM-QC1 Capacitance Box Overview
The FM-QC1 adjustable capacitance box is a precision instrument designed for laboratory measurements and industrial testing applications. With a capacitance range spanning from 68pF to 2200pF across 6 selectable steps, this unit features a rotary switch mechanism for smooth range selection. The device incorporates high-stability polypropylene film capacitors and silver-copper contact switches to ensure measurement consistency. Its shielded metal enclosure effectively minimizes electromagnetic interference during sensitive circuit evaluations. 47
Key Functional Features
This capacitance box offers three distinctive functions: E6 series nominal values for common circuit testing requirements, adjustable loss tangent (tgδ) simulation for different dielectric characteristics, and a blind-test mode for examination purposes. The front panel includes standard terminals (1/2 for measurement and 0 for ground connection) supporting both two-terminal and three-terminal connection methods. The compact 320×110×115mm chassis contains all electrical components within an EMI-shielded enclosure, suitable for benchtop use in environments with temperatures between +10℃ to +35℃. 820
應用場景說明
該產(chǎn)品廣泛應用于電子工程教學實驗，可配合交流電橋完成電容參數(shù)測量實驗，也可作為濾波電路、移相網(wǎng)絡(luò)中的可調(diào)容抗元件。在科研領(lǐng)域，適用于需要精確控制電容值的電路原型開發(fā)。產(chǎn)品采用耐用的機械結(jié)構(gòu)和防塵設(shè)計，適合在實驗室、測試車間等場所長期使用。隨機不包含連接線材，用戶需根據(jù)實際需求選用適當長度的測試導線以獲得最佳測量效果。148
Application Scenarios
Ideal for educational laboratories, the FM-QC1 facilitates capacitance measurement experiments when paired with AC bridges, and serves as a variable reactance component in filter circuits or phase-shift networks. Researchers benefit from its precision adjustment capability during circuit prototyping. The robust mechanical construction with dust-resistant design ensures reliable performance in laboratories and testing facilities. Note that test leads are not included, allowing users to select appropriate cable lengths for specific measurement requirements. 413
