spurious variation in the electrical output not present in the
input, defined quantitatively in terms of an equivalent
parasitic, transient resistance in ohms, appearing between the
contact and the resistant element when the shaft is rotated.
The equivalent Noise Resistance is defined independently of
the resolution, functional characteristics and the total travel.
The magnitude of the Equivalent Noise Resistance is the
maximum departure from a specific reference line. The wiper
of the potentiometer is required to be excited by a specific
current and moved at a specific speed.

Trimmer “Abilities”
When you are selecting components for a new design, you
typically take into account the environmental conditions that the
components will need to endure during the lifetime of the
instrument or device. Designers in the past have often
overlooked the environmental extremes of their own production
lines, where the conditions may be much more severe than
anything encountered in actual end use.

specified allowable degradation. A cycle is defined as one
complete traversal of the wiper over the resistive element in
both directions.

while remaining within specified allowable degradations.
