Min.-values to the lower display. After 5 seconds, the analog signal is
indicated again.
RESET: The Max.- and Min.-values are set to
actual.
ZERO SET: The zero is set to the applied
pressure.
ZERO RES: Restores the instrument back to factory
settings.
UNITS: The pressure values can be displayed in different
units.
