Me too, I find it interesting that it can determine the polarity (direction of current flow) in the DC circuit; it has a built in "Left-Hand Rule".

For those here that had Basis Electric Theory taught to them, where they were introduced to the "Left Hand Rule"? If so, is this the way you remember it?

Definition of left-hand rule

:a rule in electricity: if the thumb and first two fingers of the left hand are arranged at right angles to each other on a conductor and the hand oriented so that the first finger points in the direction of the magnetic field and the middle finger in the direction of the electric current then the thumb will point in the direction of the force on the conductor.

So, I wonder if, holding the meter in your left hand or right hand or, the orientation on any axis makes a difference in the readings? (JK)
