ITEM NAME   RESISTOR,VARIABLE,N
DEFINITION  A resistor in which a sliding or rolling contact moves over an exposed
             area of the resistive element to change the ohmic value of the output.
             The functional tolerance (linearity), if given, of the output is
             greater than plus or minus 1 percent on linear outputs. Specified
             outputs such as sine, cosine, tangent, etc., shall be considered to be
             precision. For items having manually positioned taps designed to be
             set and fixed prior to use, see RESISTOR, ADJUSTABLE. For items with
             step by step variation, see RHEOSTAT and RESISTOR, STEP BY STEP. For
             tandem-mounted items designed to function together as an attenuator
             (and rated accordingly), see ATTENUATOR, VARIABLE. Excludes RESISTOR
             (1), VARIABLE, WIRE WOUND, NONPRECISION; RESISTOR (1), VARIABLE,
             NONWIRE WOUND PRECISION; and RESISTOR (1), VARIABLE, WIRE WOUND,
             PRECISION.
