Operating functions
Note
Zero point calibration
For absolute pressure transmitters, the start of scale value is at vacuum.
A zero-point calibration with pressure transmitters which do not measure absolute pressure
leads to faulty settings.
Note
Locking of buttons and functions
Local operation is possible if you are in measuring mode and neither "L", "LA" nor "LL" is
output in the mode display.
If operations are disabled, parameters can still be read. An error message is output if you try
to change parameters.
