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 001 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) / 01 s / 05 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 measured 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 displayed in the
following units:
bAr (= mbar), H2O (inH2O), PA (= kPa)
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 conversion of the units and enables
exact setting of the values
Setting at the factory: Uni = bAr
