Opens the screen for entering the values table (the table rows are
interpolated linearly, values outside of the defined table are extrapolated
linearly.)

Time basis Specifies the desired time unit (value/sec., value/min., ...) for the result
Offset Offset that is added following multiplication with the "Factor" parameter.
The result is converted in to the desired time unit before the
multiplication with the "Factor" parameter.
Factor Factor with which the result is multiplied once it has been converted into
the desired time unit. The "Offset" parameter is then added.
Note:
Additional explanation: Delta mode
Assumption: The source channel contains the meter reading of an infinite counter in m

. The calculated channel 1
should contain the flow rate in m
3
/s and calculated channel 2 should contain the flow rate in l/h.
