You should set this value as close as
possible to the expected power value to get
the best possible graphical display. If
measured values exist which are larger than
the upper measurement range, these are not
lost. The scale of the Y-axis can be changed
again in the graph at any time later on.
This brings you back again to the display
shown on the right. In the example, a power
is shown at channel K, and the difference at
channel L
.
If you have made an invalid setting, or you
have connected 2 sensors with different
measurement ranges for the differential, for
example, the relevant calculated channel is
deactivated. In the example, a pressure
transmitter with measurement range of 0-100
bar has been connected to channel C and a
pressure transmitter with a measurement
range of 0-250 bar has been connected to
channel D.
Therefore channel L would be automatically
deactivated.
