6.5 Calibration procedure notes
Prerequisites
– The calibration device is in place or the programming
inputs are connected.
– The transducer is connected to the system controller.
– Voltage or current values from the transducer can be
read (using a multimeter or the system controller).
Values for zero and end point
– Any desired position of the magnet can be used as the
zero or end point. However, the zero and end points
may not be reversed.
– The absolute zero and end points must lie within the
minimum or maximum limits of what can be output
(see value table).
– The distance between the null point and end point
must be at least 4mm.
The last set values are always saved, regardless
of whether the setting was ended using the
buttons, the programming inputs or
automatically after 10min. have expired.
Value table for teach-in and adjustment
