Submenue "Display mode"
In the "Display mode" submenue, you configure the representation of the measured values
and additional information on the display.
With the menue item “Screen layout” you configure the information that is displayed and its
layout. Up to four values can be displayed at the same time. In the additional menue en-
tries "1st value" to "4th value" you define the contents of the placeholders in the layout.
The various layouts as well as the possible content of the values are described in Chapter
6.2.4.
6.4.5
Menue "Measurement/Output"
Configure the measured value as well as the current output in the "Measurement/output"
menue.
Menue entry
Description
Damping
Setting the damping of the output signal
Output function
Setting the output function (linear, inverse)
Lower range val.
Setting the pressure value that shall correspond to 4 mA (start of
range)
Upper range val.
Setting the pressure value that shall correspond to 20 mA (end of
range)
Alarm current
Select the alarm current: High (>21 mA) or low (<3.6 mA)
Minimum current
Limit of the lower output current (3.8…4.0 mA)
Maximum current
Limit of the upper output current (20…21 mA)
Table 13: "Measurement/Output" menue
Independent from the setting of the minimum and maximum current limit, the set measur-
ing range always corresponds to a current range of 4…20 mA.
6.4.5.1
Setting the damping
Using an adjustable damping you can eliminate fast pressure changes or peaks from hav-
ing direct influence to the output signal. The set value in seconds corresponds to the time
constant of an exponential rise. After a sudden pressure change, it takes the damping time
to reach 63.2% of the actual pressure at the output. After the damping time has elapsed
three times, 95% of the pressure is reached.
