Make sure that the physical quantity selected for the calculation channel can be calculat-
ed from the physical quantities of the selected measuring channels. Possible combina-
tions are shown in Tab. 13.2.
Two cut-off flow values for each calculation channel can be defined. They are defined in
the unit of measurement of the physical quantity selected for the calculation channel.
Select the physical quantity to be calculated. Press EN-
TER.

example: The difference of the volume flow rates of the channels A and B is to be cal-
culated.
The physical quantity of channel A and B can be the volumetric flow rate or
the mass flow rate, but not the flow velocity. The physical quantities of the
two measuring channels do not need to be identical (channel A = mass flow
rate, channel B = volumetric flow rate).
Select the unit of measurement. Press ENTER.
All positive calculated values that are lower than the limit
will be set to 0.
All negative calculated values that are greater than the lim-
it will be set to 0.
The data logger can be activated/deactivated. Press EN-
TER.
