Details
This command sets the scale factor (m) for an mx + b operation for the selected measurement
function.
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
If you send this command without the
<function>
parameter, it will set the scale factor for all
measure functions.
