Example
:CALC:VOLT:MATH:FORM MXB
:CALC:VOLT:MATH:MMF 0.80
:CALC:VOLT:MATH:MBF 50
:CALC:VOLT:MATH:STAT ON
Set the math function for voltage measurements to mx+b.
Set the scale factor for voltage measurements to 0.80.
Set the offset factor to 50.
Enable the math function.

<function>
The measure function:

Current:
CURRent[:DC]

Resistance:
RESistance

Voltage:
VOLTage[:DC]
<value> The reference used when the math operation is set to percent; the range is -1e12 to
+1e12
<DEF|MIN|MAX> The
DEFault
,
MINimum
, or
MAXimum
value
Details
This is the constant that is used when the math operation is set to percent.
The percent math function displays measurements as percent deviation from a specified reference
constant. The percent calculation is:
Where:
•
Percent is the result
•
Input is the measurement (if relative offset is being used, this is the relative offset value)
•
Reference is the user-specified constant
