Details
This attribute is not available for "nofunction". If you write this attribute for "nofunction", an
error message is generated.
When this command is set to on, the math operation specified by the math format command is
performed before completing a measurement.
Example
dmm.func = "dcvolts"
dmm.reset("active")
dmm.measurecount = 5
MathBuffer = dmm.makebuffer(100)
MathBuffer.appendmode = 1
dmm.measure(MathBuffer)
dmm.math.format = dmm.MATH_MXB
dmm.math.mxb.mfactor = 1e6
dmm.math.mxb.bfactor = 0
dmm.math.mxb.units = "["
dmm.math.enable = dmm.ON
Configure the DMM for DC volts.
Reset DC volts to the default settings.
Set the measure count to 5.
Create a reading buffer named MathBuffer that can
store 100 readings.
Set the buffer to append readings.
Take 5 readings and store them in MathBuffer with
no math operation.
Enable math operations for mx+b operation, with m
set to 1e6 and b set to 0, with units set to micro.
