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 4mm.
The last set values are always saved, regardless 
of whether the setting was ended using the 
buttons, the programming inputs or 
automatically after 10min. have expired.
Value table for teach-in and adjustment
The following examples refer to transducers 
with 0 to 10 V or 4 to 20 mA output.
