Calculation expression
(A ∗ CHa  B ∗ CHb  C ∗ CHc  D ∗ CHd)
A, B, C, D, E: User-specified constants
CHa, CHb, CHc, CHd: User-specified measurement channels (up to 4 channels)

or a blank character
If entering a blank character, you cannot enter a constant.
Example: To write an expression (A∗CH1)
You can select a calculation channel as a target channel; however, you cannot select a calculation
channel with a number that is larger than the number of the configured calculation channel.
Example: You can set

This setting allows you to enter channels, coefficients, and constants.
(You can also set exponents as constants.)
If division by zero is found, the calculation will result in 1.797693e+308.
