Incorporated Fixed Resistor
A fixed resistor can be incorporated in the Series 110
at the end of CW or CCW rotation to a minimum of 10%
of the total resistance. The rotation is shortened by an
amount proportional to the ratio of the fixed resistor to
the total resistance. Available at extra cost.

Resistor Adjustment
Standard Cross Slot: Provided in drive plate for screwdriver
adjustment.
Special Molded Knob: Available at extra cost secured to
drive plate cross slot.
