Programming lock
In order to prevent unauthorised adjustment of the device, a programming lock can be set. If the
menu item "PrG" is set to "Loc" in the extended menu, the programming lock is set. All values can
still be read but can't be edited. When trying to edit a value by means of the arrow keys, "Loc" is
displayed as long as the key is pressed. The functions "reS" and Rs.HL" are locked as well.
