FLUXUS G60x 13 Advanced Measuring Functions
A calculation channel can not be attenuated. The damping factor has to be set separately
for each of the two measuring channels.
Two cut-off flow values for each calculation channel can be defined. The cut-off flow is
not based on the flow velocity as for measuring channels. Instead, it is defined in the unit
of measurement of the physical quantity selected for the calculation channel. During the
measurement, the calculated values are compared to the cut-off flow values and set to
zero if necessary.
A calculation channel provides valid measured values if at least one measuring channel
provides valid measured values.
13.7.2 Parameterization of a Calculation Channel
13.7.3 Output Options for a Calculation Channel
Select a calculation channel (Y or Z) in the program branch
Parameter. Press ENTER.
The current calculation function is displayed. Press EN-
TER to edit the function.
Three scroll lists are displayed in the upper line:
• selection of the first measuring channel (ch1)
• selection of the calculation function (funct)
• selecton of the second measuring channel (ch2)
Select a scroll list with key or .
The list items are displayed in the lower line.
Scroll with key and through the scroll list. All mea-
suring channels and their absolute values can be used as
input channels for the calculation.
The following calculation functions are available:
• -: Y = ch1 - ch2
• +: Y = ch1 + ch2
• (+)/2: Y = (ch1 + ch2)/2
• |-|: Y = |ch1 - ch2|
Press ENTER.
Select a calculation channel in the program branch Out-
put Options. Press ENTER.
