With rated voltage applied between terminals 1 and 3, the straight line which
connects the measured output values VB and VA at specified reference positions
B and A is assumed to be an ideal straight line, so that deviation against the ideal
straight line when the voltage applied between terminals 1 and 3 is assumed to be
100％ can be expressed as a percentage.

Resistive Position Sensors / Measurement and Test Methods
Resistive Position Sensor
〔Total
Resistance〕
The total resistance, with the shaft（lever）placed at the end of terminal 1 or 3, shall be determined by
measuring the resistance between the resistor terminals 1 and 3 unless otherwise specified.
〔Rating Voltage〕
The rating voltage corresponding to the rated power shall be determined by the following equation. When the
resulting rated voltage exceeds the maximum operating voltage of a specific resistor, the maximum operating
voltage shall be taken as the rated voltage.
E=√ P・R
