Hello... tomorrow i've to give this vi to my teacher.... my pursuit
is creating a driver for agilent 34401A. I've to do a casual number of
measurements of a signal, then i've to show the result of measurement
considering "type A and B uncertainly"!
Could you control if this driver is ok?
In the pics there are the multimeter's specifications...
remember that:
for type b uncertainly we consider only "one year range"
you should read that documentation more carefully!
Accuracy is (typically for DMMs) defined as % of reading + % of range. So when you measure a value of 1V in a 2V range you have an accuracy of let say 0.05% of 1V + 0.02% of 2V = 0.05+0.04V = 90mV. You can't just add all those numbers!
You always have to use the measurement value and range for uncertainty calculation!
