Model RDC10/RD7
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.
