Hybrid track potentiometers feature a high wiper contact resistance, therefore operational checks
should be carried out only in the voltage divider mode. Hybrid track potentiometers should be
used only as voltage dividers, with a minimum wiper circuit impedance of 100 x track resistance
or 0.5MΩ (whichever is greater). Operation with wiper circuits of lower impedance will degrade
the output smoothness and affect the linearity
