Function of the display
The digital display has two types of display:
•
Display in measurement mode: This is shown as standard
•
Display in calibration mode: This is shown after pressing the Zero or Span
key once. It returns automatically to measurement mode after 2 seconds

Function
Switch position "off": Damping 0 s
Switch position "on": Damping 2 s.
This switch position also enables any damping to be entered between
0 s ... 40 s by remote communication e.g. with the handheld terminal.
press once: The acting pressure for the zero point is shown
press twice: The acting pressure for the zero point is adopted
press once: The acting pressure for the measuring span is shown
press twice: The acting pressure for the measuring span is adopted
press once simultaneously: The acting pressure is shown as the
bias pressure
