Details
The percent math function displays measurements as percent deviation from a specified reference
constant. The percent calculation is:
Where:
•
Percent
is the result
•
Input
is the measurement (if relative offset is being used, this is the relative offset value)
•
Reference
is the user-specified constant
Example
dmm.digitize.func = dmm.FUNC_DIGITIZE_CURRENT
dmm.digitize.math.format = dmm.MATH_PERCENT
dmm.digitize.math.percent = 42
dmm.digitize.math.enable = dmm.ON
Set the measurement function to current.
Set the math operations to percent.
Set the percentage value to 42 for voltage
measurements.
Enable math operations.
