Method for Regulating the Linearity

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.

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.
