Adjustable parameters
ASP
Analogue start point
Measured value at which 4 mA is provided.
AEP
Analogue end point
Measured value at which 20 mA is provided.
Minimum distance between ASP and AEP = 25% of the span.
Setting range:
mbar
kPa
inH
2
mmWS
HI
Min-Max memory for system pressure
• HI: displays the highest measured pressure.
LO
• LO: displays the lowest measured pressure.
COF
Calibration offset
The internal measured value (operating value of the sensor) is
offset against the real measured value.
• Setting range: -5 ... +5% of the value of the span
(with scaling as factory setting (ASP = 0 mbar and
AEP = 250 mbar),
• in steps of 0.1% of the value of the span.
CAr
Calibration reset
Resets the calibration set by COF.
dAA
Damping for the analog output
Pressure peaks of short duration or high frequency can be filte-
red out.
dAA-value = response time between pressure change and
change of the switching status in milliseconds (ms).
• setting range: 0 (= dAA is not active) / 0.1 s / 0.5 s / 2 s.
Uni
Display unit
The measured values and values for ASP / AEP can be indicated
in the following units: mbar, kPA, inH
Select the display unit before setting the limits for the analog
output signal (ASP, AEP). This avoids rounding errors generated
internally during the conversion of the units and enables exact
setting of the limits for the analog output signal.
