| This discussion of variable-resistor characteristics uses the following definitions: (a) Ratio tolerance=RA/RB vs setting. (b) Resistance tolerance is the tolerance on the resistance between points A and B. (c) End-resistance tolerance defines the range of resistances with the wiper shorted to terminal A. (d) Taper—usually linear or logarithmic—refers to the resistance change vs equal increments in the mechanical setting. |
