Model RDC10
This is the deviation to an ideal line shown below
when the voltage applied between terminals 1 and 3 is
assumed to be 100%.
（Unit:percentage）
With rated voltage applied between terminals 1 and 3,
the ideal line is assumed to be the straight line drawn
between the measured output values V

at
specified reference positions B and A.
