扭摆共振式微电流计研制

摘要

The weaker tester with photoelectric detection is designed based on the operational principle of the torsional pendulum. The measurement error range of the designed weak current tester is within 5% compared with the commercial one.%基于扭摆转动原理,设计出扭摆共振式光电探测型微电流计,介绍了实验原理和装置.实测结果表明,与商用电流计的标称值相比,该电流计的测量相对误差范围在5％以内.
