Percent Deviation
NOTE Percent deviation is not a built-in math expression for remote operation. This pro-
gram example creates the following percent deviation (PER_DEV) calculation to
test 10k
Ω resistors. This user-defined math expression is added to the catalog.
Where: RES is the actual measured resistance of the DUT.
10k Ω is the reference value.
