Details

This specifies which math operation is performed on measurements for the selected measurement

function.

You can choose one of the following math operations:

• y = mx+b: Manipulate normal display readings by adjusting the m and b factors.

• Percent: Displays measurements as the percentage of deviation from a specified reference constant.

• Reciprocal: The reciprocal math operation displays measurement values as reciprocals. The displayed

value is 1/X, where X is the measurement value (if relative offset is being used, this is the measured

value with relative offset applied).

Math calculations are applied to the input signal after relative offset and before limit tests.

Example

dmm.digitize.func = dmm.FUNC_DC_VOLTAGE

dmm.digitize.math.format = dmm.MATH_RECIPROCAL

dmm.digitize.math.enable = dmm.ON

Enables the reciprocal math operation on

digitize voltage measurements.
