6.6 PIN Number and Calibration Switch
Calibration can be protected against accidental or incorrect calibrations, through the
use of a rear calibration switch and a special PIN number.
The calibration button is located on the rear panel, and can be pushed with a pointed
object (pen, pencil, paper clip, etc.). This button can be pushed after the calibration
menu has been selected. At the same time, a request to input the PIN number will
appear in the display.
