User-Definition Computation Syntax
The measured result is entered in variable M. The computed result can be substituted
into variable M to further carry out computation.
For example, if you wish to display the result of subtracting 0.75 from 1.25 times the
measured value, write the equation as follows:
M = M*1.25 – 0.75
The available binary operators are listed below.

Equations using functions can also be written.
For example, if you wish to compute the absolute value of the measured value, you can
use the absolute value function ABS() as follows:
M = ABS(M)
