Set Damping For The Analogue Signal; Calibrate Curve Of Measured Values - ProMinent DULCOMETER PH-501 Assembly And Operating Instructions Manual

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.
