Autozero circuit that allows the user to automatically adjust the zero-point virtual ground terminal of the scope with the ...

HALL EFFECT SENSOR The current package for the Hall effect sensor is very much like a transistor. It is a three lead in line device in a low-level transistor size black plastic case. Also available ...

But, Hall-effect current sensors have traditionally exhibited significant drift over temperature and lifetime.

Using the SS49E linear Hall effect sensor in pairs on four sides of a square, the setup proves quite straightforward.
