On/Off
Set the channels that you want to use to On.
Computation is performed every scan interval, starting with the smallest channel number.
Example: If you specify A002=A001+A003, the value of the previous scan interval is used for
A003.
Calculation expression
Set the expression.
In computations, measured values are handled as values without units. For example, if the
measured data from channel 0001 is 20 mV and the measured data from channel 0002 is
20 V, the computed result of 0001 + 0002 is 40.
