Adjust with the calibration device

7.1

Calibration device

The calibration device is an additional device for calibrating
the transducer if configuration with a PC and software is
not possible.
Prerequisite
Button function has not been locked by the PC
software (button lock).
Calibration device is in place
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).
If the button function is locked, this lock must
be removed using the PC software.
Settings
The transducer has the following factory settings that can
be adjusted with the calibration device:
One magnet,
"position" function at both outputs, output 1 with a
rising curve and output 2 with a falling curve,
identical measuring range for both outputs.
During adjustment, the same start points and end points
are set for both outputs. No other function can be selected
and no further transducer may be used.
If the button function is locked, the lock can only be
removed if these conditions have been fulfilled.

Calibration procedure notes

► Before calibrating: Place the calibration device on the
connection side of the transducer.
► When finished with calibration: Remove the calibration
device to prevent changes.
► Keep the calibration device for later use.

Values for null and end point
Any desired position of the magnet can be used as the
null or end point. However, the null and end points may
not be reversed.
The absolute null and end points must lie within the
minimum or maximum range of what can be output.
The distance between the null point and end point
must be at least 4 mm.

If the buttons on the calibration device are not
pressed for approx. 10 min, programming mode
is automatically ended.
The last set values are always saved, regardless
of whether the setting was ended using the
buttons or automatically after 10 min have
expired.
