<Calculation formula>
The calculation formula is as follows.
Calculated data = {(a * CH-X) [+|–|*|/] (b * CH-Y) + c} * <Scaling>
By adjusting a, b and c, it is possible to support various Calculation formulas.
Example of settings
Calculation formula
CH1+CH2
3.0 * CH5+100
(2.5 * CH2)/(2.0 * CH3) – 20
<Scaling>
Scaling adjusts the unit of the calculation result.
For example, if the calculation result is "V" and you want the unit to be "mV", set the scaling to "*1000".
