Re: speedometer error
Bend the arm for an accurate reading, and the stops will be off.
I think all analog meters function the same was. Magnet and a coil that electricity flows through; the spring returns the needle back to the beginning stop. The only difference is how much energy is needed for full scale deflection; lower amounts equate to more accurate.
If I remember correctly, its the current thru the coil that creates the magnetic field, moving the needle.
