⁵) zero point- and range adjustment are made on the receiving unit
⁶) depending on the mounting of the positioner respectively of the travel range a deviation up to 5% is possible
⁷) passive element, therfore no certificate of conformity is needed,
but the outer inductivity and capacity (La u. Ca)
have to be bigger than Li and Ci of the potentiometer.
