如何测准灵敏检流计的内阻

How to Survey Accurately Internal Resistance of Sersitive Currentmeter

本文分析了灵敏检流计内阻的通常测法遇到的困难。采取加设反向开关和减小检流计回路电阻等措施 。

The difficulty of usual measure way in internal resistance of sensitive currentmeter was analysed.If the way equipping extra reversed switch and reducing the resistance of the loop of the currentmeter was adopted,it would get more accurate result of measurement than usual.
