I wish to use a bridge circuit to calibrate a meter with ten major divisions. (I understand how a Wheatstone null meter works) What I'm really interested in doing is calibrating my meter so that I can measure the voltage in an unbalanced condition. i.e., if the meter in the balanced condition shows 25 VDC at division "0", then how can I make the meter read 0.5 VDC at each division above "0" and -0.5 VDC
at each point below "0"?
at each point below "0"?
