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 chan-
ge of the switching status in seconds (s).
• Setting range: 0 ... 4 s (0 = dAP is not active),
• in steps of 0.01 s.

Correlation between switching frequency and dAP: f =
max
2 × dAP
Damping for the analogue signal
Pressure peaks of short duration or high frequency can be
filtered out.
dAA-value = response time between pressure change and
change of the switching status in seconds (s).
• Setting range: 0 (= dAA is not active) / 0.1 s / 0.5 s / 2 s.
dAA is active only if OU2 = I or U.
Setting of the display
9 options can be selected:
d1 = update of the measured value every 50 ms
d2 = update of the measured value every 200 ms
d3 = update of the measured value every 600 ms
The update interval only refers to the display. It has no effect on
the outputs.
ph = display of the measured peak value remains for a short
time (peak hold).
rd1, rd2, rd3, rph = display as d1, d2, d3, Ph; but rotated 180°.
OFF = In the Run mode the display of the measured value is
deactivated. If one of the buttons is pressed, the current measu-
red value is displayed for 15 s. Another press of the Mode/Enter
button opens the Display mode. The LEDs remain active even if
the display is deactivated.
Display unit
The measured value and the values for SPx / rPx can be display-
ed in the following units:
bAr (= mbar), H2O (inH O), PA (= kPa).
2
Select the display unit before setting the switch points (SPx, rPx)
and the limits for the analogue output signal (ASP, AEP). This
avoids rounding errors generated internally during the conversi-
on of the units and enables exact setting of the values.
Setting at the factory: Uni = bAr.
