TH0200 DC Current Ratio Standard

测量超精密直流电流,校准精密直流电流比较仪、直流电流传感器、直流大电流源、精密直流分流器、直流功率或电能计量标准等设备


工作频率范围为 DC ~ 5 kHz

测量正反向直流电流

正向直流比例精度最高可达 0.5 ppm



Overview

Model TH0200, a series of high-precision DC current ratio standards, can measure DC current in forward and reverse directions. Operating frequency range is from DC to 5 kHz, primary input and secondary output are completely electrically isolated.

Forward DC ratio accuracy is up to ±0.5 ppm. Combine with 8½ digital multimeters (or nanovoltmeters) and 2 the model TH0310 - 1 Ω high-power reference resistors, to obtain self-tracking accuracy of DC current with the optimal uncertainty from 0.5 ppm to 2 ppm.

Applications

 Ultra-precision DC current measurement

● Calibrate precision DC current comparators

 Calibrate DC current sensors

 Calibrate DC high-current standard sources

 Calibrate precision DC shunts

 Calibrate DC power or electrical energy
