Details
This attribute specifies the offset (b) for an mx + b operation.
The mx + b math operation lets you manipulate normal display readings (x) mathematically according
to the following calculation:
y = mx + b
Where:
•
y
is the displayed result
•
m
is a user-defined constant for the scale factor
•
x
is the measurement reading (if you are using a relative offset, this is the measurement with relative
offset applied)
•
b
is the user-defined constant for the offset factor
Example
dmm.digitize.func = dmm.FUNC_DIGITIZE_CURRENT
dmm.digitize.math.format = dmm.MATH_MXB
dmm.digitize.math.mxb.mfactor = 0.80
dmm.digitize.math.mxb.bfactor = 42
dmm.digitize.math.enable = dmm.ON
Set the measurement function to voltage.
Set the scale factor for the mx +b operation
to 0.80.
Set the offset factor to 42.
Enable the math function.
