Hello every body,
i am doing a project for testing reed switches. For measuring Contact Resistance of Reed Switch i am using the circuit which is attached with this post. But with this circuit hardly i can differentiate between 48 milliohms and 36millohms because the measured voltage when Switch is closed is too close to differentiate . So does anyone know any other circuit so this problem can be avoided
