Usage
:CALCulate[1]:<function>:MATH:MMFactor <value>
:CALCulate[1]:<function>:MATH:MMFactor <DEF|MIN|MAX>
:CALCulate[1]:<function>:MATH:MMFactor?

<function>
The measure function:
 Current: CURRent[:DC]
 Resistance: RESistance
 Voltage:
VOLTage[:DC]
<value>
The scale factor; the valid range is −1e12 to +1e12
<MIN|MAX|DEF>
The DEFault, MINimum, or MAXimum value
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
r
elative 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.
