STD MATH
DEFINITION:
2 mathematical functions are included as standard in the recorder.

POSSIBLE CHOICES:
NO OPT MATH: No maths function configured.
SQUARE ROOT: Square root applies to analog input.
CHANNEL DIFF: Difference between the current analog input and the one
configured in "DIFF WITH".
SEE ALSO:
DIFF WITH in this sub-matrix for CHANNEL DIFF.
NOTE:
1) For SQUARE ROOT the formula is:
Smin = min. sensor input value
Smax = max. sensor input value
S = current sensor input value
Available for linear inputs
2) For CHANNEL DIFF, the formula is:
PV = PV
A - PVB
A and B are any analog input.
