Display mode
3 settings can be selected:
Mod1 = displayed differential pressure.
Mod2 = displayed differential pressure,
after locking: trend display of the gap (gap between
the differential pressure and switch point 1).
Mod3 = in the Run mode the trend display of the gap is shown,
when the Mode button is pressed: differential pressure
is displayed for 15 s as numerical value in the set display
unit.
Factory setting: Dmod = Mod2
Trend display:
Hysteresis for SP1/SP2
The gap between the switch-on and switch-off points is set
• Setting range : 8 ... 50 mbar.
• Default value: 12 mbar.
Calibration offset
The internal measured value (operating value of the sensor) is
offset against the real measured value.
• Setting range: -5 ... +5% of the span,
• in steps of 0.1% of the span.
Calibration reset
Resets the calibration set by COF to the value set at the factory.
- Press the "Mode/Enter" button until CAr is displayed.
- Press the "Set" button and keep it pressed until "- - -" is
displayed.
- Then press the "Mode/Enter" button briefly.
Output polarity
2 options can be selected:
- PnP = positive switching
- nPn = negative switching
This setting applies to both switching outputs.
Damping for the switching outputs
Pressure peaks of short duration or high frequency can be filtered
out. dAP-value = response time between pressure change and
change of the switching status in seconds (s).
• Setting range: 0 ... 4 s (0 = dAP is not active),
• in steps of 0.01 s.
