P29 Instruction Manual
20
Output
With this parameter, you can select the output and output range. You can choose from the
following options:
4 … 20 mA
0 … 20 mA
-
5V … +5V
0V … 10V
Filter
The measured pressure values can be smoothened by a filter before they reach the display or
analogue output. This parameter lets you set a time constant for this filter.
Warning signal
With this parameter, the signal that a key has been pressed can be switched on or off.
Resolution
This parameter affects the display resolution. The display is changed according to the adjusted
values. For example, if the setting is 1%, the display changes to showing the measuring range
in 1% jumps. This can be used with severely fluctuating pressures to steady the display.
However, this does not have any affect on the warnings.
Zero-point calibration
This parameter specifies the time interval for the automatic zero-point calibration. The entry is
in min. Setting the parameter to 0 deactivates automatic zero-point calibration.
CS (creep suppression)
This parameter specifies the value for creep suppression as a percentage. If this value falls
short of the measured pressure value, the display is set to zero. Creep suppression only works
with volumetric flow, mass flow and flow rate (root-extracted measurement values).
Lightning
With this parameter, the colour of the backlight of the LC display, in the menu or when the
colour change is switched off, can be selected. There are three options to choose from:
off
backlight is switched off
white backlight is white
blue
backlight is blue
Colour change
This parameter can be used to select whether or not the display background changes colour
when a limit value is exceeded. There are two options to choose from:
off
colour change is switched off
on
colour change is active
When a value set in the warnings is exceeded, the display turns yellow for the time Tv or Tn
and then changes to a red backlight after the warning is active.
Brightness
With this parameter, the brightness of the backlight can be set. Values between 0( dark) and
16( bright) are possible.
