9.4.5 Set damping for the analogue signal
►
Select [dAA] and set a value between 0�01 and 30 s�
dAA value = response time between pressure change and change of the
analogue signal in seconds�
9.4.6 Calibrate curve of measured values
If the unit is to adopt the settings for the calibration points, the following conditions must be
adhered to:
-CP1 and CP2 must be within the measuring range (i�e� between ASP and AEP)�
-CP1 and CP2 must not be in the extended display range�
-Minimum distance between the calibration points CP1 and CP2 = 5 % of the final value of
the measuring range�
-Maximum correction value = ± 2 % of the final value of the measuring range�
►
Set a defined reference pressure between ASP and AEP in the system�
►
Select [CAL]�
►
Touch [Set] briefly�
> [CP1] is displayed�
►
Touch [Set] for 5 s�
> The pressure measured by the unit is displayed�
►
Touch [Set] until the set reference pressure is indicated (measured
pressure = reference pressure) or the corresponding analogue signal is
provided to OUT2�
►
Touch [Mode/Enter] briefly�
> [CP1] is displayed�
►
Touch [Mode/Enter] briefly�
> [CP2] is displayed�
Continue with a) or b)�
a) Finish calibration:
►
Touch [Mode/Enter] briefly�
> [CAL] is displayed�
b) Change a 2nd point on the curve of measured values:
►
Set a second defined reference pressure in the system�
►
Touch [Set] for 5 s�
> The pressure measured by the unit is displayed�
►
Touch [Set] until the set reference pressure is indicated (measured
pressure = reference pressure) or the corresponding analogue signal is
provided to OUT2�
►
Touch [Mode/Enter] briefly�
> [CP2] is displayed�
►
Touch [Mode/Enter] briefly�
> [CAL] is displayed, the process is finished�
