<function>
The measure function:
• Current: CURRent[:DC]
• Resistance: RESistance
• Voltage: VOLTage[:DC]
The digitize function:
• Digitize current: DIGitize:CURRent
• Digitize voltage:
DIGitize:VOLTage
<n>
The scale factor; the valid range is −1e12 to +1e12
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. It will not change the setting for a digitize function.
