The resistance measured between the wiper terminal and an end terminal with the shaft positioned at the corresponding End Point. Typically express as a maximum ohmic value or a percentage of the total resistance value.

The apparent resistance seen between the wiper and the resistance element when the wiper is energized with a specified current and moved over the adjustment travel in either direction at a constant speed. The output variations are measured over a specified frequency bandwidth. CRV is expressed in ohms or as a Percent of Total Resistance.

The unit change in resistance per degree celsius change from a reference temperature, expressed in parts per million per degree celsius as follows:


Where:
R1 = Resistance at reference temperature in ohms.
R2 = Resistance at test temperature in ohms.
T1 = Reference temperature in degrees celsius.
T2 = Test temperature in degrees celsius.
