FMUJ36a直流(低)电位差计
产品概述
FMUJ36a直流(低)电位差计是一款便携式高精度测量仪器，采用补偿法原理设计，适用于实验室、车间及野外环境下的直流电压（或电动势）测量。该设备无需外接附件即可直接测量热电偶热电势，通过换算还可用于直流电阻、电流等参数的测量。仪器内置集成放大器和基准电源，采用干电池供电，有效避免工业干扰，确保测量稳定性。312
技术特点
FMUJ36a具备0.1%的测量精度，提供×0.2档（0~46mV）和×1档（0~230mV）两档量程，最小分度值分别为10μV和50μV。仪器采用锰铜合金双线无感绕制电阻，经人工老化处理确保长期稳定性。工作电流为6mA，由4节1.5V干电池供电，可持续工作约200小时。整机重量约4kg，尺寸为270×230×140mm，配备防震外壳，适合移动使用。3615
功能应用
该电位差计可校验各类毫伏表、电子电位计等工业仪表，配合热电偶能快速检测温度并校准二次温度仪表。通过标准电阻扩展功能，可实现直流电阻、电流的间接测量。仪器特别设计测量-输出切换开关，可输出标准电压信号用于设备调试。内置晶体管放大检流计灵敏度达1μV/格，支持快速零点校准。21223
使用优势
FMUJ36a操作简便，开机预热3分钟后即可通过步进盘和滑线盘完成测量，读数直观。采用独立电池供电方案，不受场地限制，在5℃~35℃环境温度下均能保持性能。仪器配备防短路保护电路，耐500V交流电压冲击，核心部件绝缘电阻大于100MΩ。维护时仅需定期更换干电池，长期存放建议取出电池。111520
Product Overview
The FMUJ36a DC (Low) Potentiometer is a portable precision instrument based on compensation principle, designed for measuring DC voltage (or EMF) in laboratories, workshops, and field environments. With built-in integrated amplifier and reference power supply, it directly measures thermocouple signals without external accessories. Battery-powered design effectively eliminates industrial interference, ensuring stable operation. 326
Key Features
This potentiometer delivers 0.1% accuracy with dual ranges: ×0.2 (0~46mV) and ×1 (0~230mV), featuring minimum resolutions of 10μV and 50μV respectively. Manganin alloy resistors with bifilar winding guarantee long-term stability. Operating at 6mA current, it runs on four 1.5V dry batteries for approximately 200 hours. The compact unit (270×230×140mm, 4kg) features shock-resistant casing for mobile applications. 61723
Functional Applications
The instrument calibrates millivolt meters and industrial potentiometers, while enabling temperature measurement via thermocouples. With standard resistors, it extends functionality to measure DC resistance and current. The built-in transistorized galvanometer offers 1μV/division sensitivity, and the measurement-output switch allows standard voltage signal generation for device debugging. 21225
Operational Benefits
FMUJ36a simplifies measurement through intuitive step and slide dials after 3-minute warm-up. Battery operation ensures mobility, maintaining performance within 5℃~35℃. Protection circuits withstand 500V AC surges, with core component insulation exceeding 100MΩ. Maintenance only requires periodic battery replacement (recommended removal during long storage). 111520
