Dmm.measure.math.format - Keithley DMM7510 Reference Manual

Section 8: TSP command reference

dmm.measure.math.format

This attribute specifies which math operation is performed on measurements when math operations are enabled.
Type TSP-Link accessible
Attribute (RW) Yes
Usage
operation = dmm.measure.math.format
dmm.measure.math.format = operation
operation
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.measure.func = dmm.FUNC_DC_VOLTAGE
dmm.measure.math.format = dmm.MATH_RECIPROCAL
dmm.measure.math.enable = dmm.ON
