100%-VALUE LINE 2 Prerequisite
The function is only available if one of the following options was selected in the ASSIGN
LINE 2 function (ä 113):
• VOLUME FLOW IN %
• MASS FLOW IN %
• CORRECTED VOLUME FLOW IN %
• HEAT FLOW IN %
• VELOCITY IN %
• BARGRAPH VOLUME FLOW IN %
• BARGRAPH MASS FLOW IN %
• BARGRAPH CORRECTED VOLUME FLOW IN %
• BARGRAPH HEAT FLOW IN %
• BARGRAPH VELOCITY IN %
Description
Use this function to enter the flow value which should be shown on the display as
the 100% value.
If a value was specified for the VALUE 20 mA function (ä 120) when ordering, this
value is also used here as the factory setting.
User input
5-digit floating-point number
Factory setting
10 l/s (for volume flow)
10 kg/h (for mass flow)
10 Nm³/h (for corrected volume flow)
10 kW (for heat flow)
FORMAT Description
For selecting the number of decimal places for the display value in the main line.
• Note that this setting only affects the reading as it appears on the display, it has no
influence whatsoever on the accuracy of the system's calculations.
• The places after the decimal point as computed by the measuring device cannot always
be displayed, depending on this setting and the engineering unit. In these instances an
arrow appears on the display between the measured value and the engineering unit
(e.g. 1.2 kg/h), indicating that the measuring system is computing with more
decimal places than can be shown on the display.
Options
XXXXX. - XXXX.X - XXX.XX - XX.XXX -X.XXXX
Factory setting
X.XXXX
DISPLAY DAMPING Description
For entering a time constant defining how the display reacts to severely fluctuating flow
variables, either very quickly (enter a low time constant) or with damping (enter a high
time constant).
• The setting 0 seconds switches off damping.
• The reaction time of the function depends on the time specified in the FLOW
DAMPING function (ä 170).
• The damping of the display only affects the flows.
• The damping of the temperature display is independent of the setting made here.
User input
0 to 100 seconds
Factory setting
5 seconds
CONTRAST LCD Description
For adjusting the display contrast to suit local operating conditions.
If you press the
P
keys simultaneously at startup, the language defaults to "ENGLISH"
and the contrast is reset to the factory setting.
User input
10 to 100%
Factory setting
50%
