Calibration procedure

6.1 Calibration device (not for BTL7-...-S140)
The calibration device is an additional device for calibrating
the transducer.
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.
Automatic deactivation!
If the buttons on the calibration device are not
pressed for approx. 10 min., programming
mode is automatically ended.
