An Amplifier for converting very small currents into larger current that can be read on a student meter. 

This amplifier has an extremely low input impedance and the gain is about 1000:1. It will amplify at very low input voltages and is designed specially for the IEC ELECTROMAGNETIC INDUCTION APPARATUS (EM1740-001).    Effectively it will convert uA of current into mA for reading on a normal student meter.

It has a "zero offset" control for best accuracy and a gain control to change the amplification from low up to 1000:1.

The unit has an internal 9V #216 dry cell and can be used for any signal amplification application.
