Any spurious variation in the electrical output not present in the input. Noise is defined in terms of an equivalent parasitic, transient resistance in ohms, appearing between the contact and the resistance element when the shaft is rotated.

The Equivalent Noise Resistance is defined independently of the resolution, the functional characteristics, and the total travel.

The magnitude of the Equivalent Noise Resistance is the maximum departure from a specified reference line. Noise is measured with the wiper excited by a specified current and moved at a specified speed.

Output Smoothness is a measurement of any spurious variation in the electrical output not present in the input.

It is expressed as a percentage of the Total Applied Voltage and measured for specified travel increments over the Theoretical Electrical Travel.

Output Smoothness includes effects of contact resistance variations, resolution, and other micrononlinearities in the output.

A measure of the sensitivity to which the Output Ratio of the potentiometer may be set.

Ability to withstand under prescribed conditions, a specified potential between the terminals and the exposed conducting surfaces of the potentiometer, without exceeding a specified leakage current value.

The resistance to a DC voltage between the terminals cup and the exposed conducting surfaces of the potentiometer, under prescribed conditions.

The maximum power that a potentiometer can dissipate under specified conditions while meeting specified performance requirements.

The decrease of the nominal power rating, usually for temperature changes.

The number of shaft revolutions obtainable under specific operating conditions.
