FM-QC1被测电容箱/FMQC1
FM-QC1被测电容箱产品概述
FM-QC1被测电容箱是一款专为实验室和工业测试设计的精密可调电容设备，采用模块化结构设计，适用于电子电路调试、教学实验及科研测量等场景。该产品提供68pF至2200pF共6档可调电容范围，通过旋钮切换档位，操作简便直观。内部采用高稳定性聚丙烯薄膜电容元件，配合银铜触点开关，确保接触可靠性和长期稳定性。产品外壳采用金属屏蔽设计，有效减少外部电磁干扰，提升测量精度。14
产品技术特点
FM-QC1具备三项核心功能：一是按E6序列标称值设计，符合常规电路测试需求；二是支持损耗角正切值（tgδ）调节功能，可模拟不同介质特性的电容；三是设有盲测档位，适用于教学考核或隐蔽测试场景。其结构设计注重实用性，所有电气部件均安装在屏蔽机箱内，面板配备标准端钮接口（1/2端钮和屏蔽接地端钮0），支持二端或三端接入方式。产品工作温度范围为+10℃至+35℃，适应常规实验室环境。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
应用场景说明
该产品广泛应用于电子工程教学实验，可配合交流电桥完成电容参数测量实验，也可作为滤波电路、移相网络中的可调容抗元件。在科研领域，适用于需要精确控制电容值的电路原型开发。产品采用耐用的机械结构和防尘设计，适合在实验室、测试车间等场所长期使用。随机不包含连接线材，用户需根据实际需求选用适当长度的测试导线以获得最佳测量效果。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
