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: → page 33.
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 bar and AEP = final
value of measuring range),
• in steps of 0.1% of the value of the span.
CAr
Calibration reset
Resets the calibration set by COF.
dAA
Damping for the analogue output
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 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:
bAr (= bar / mbar), PSI, PA (= MPa / kPa).
Select the display unit before setting 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 limits for the analogue output signal.
