Averaging Readings of the 44702A
For the 40 mV range:
accuracy = +/- (0.05% + 35 uV + 34 / N^0.5 uV)
where "N" is the number of readings averaged.
For 10 readings averaged this gives +/-(0.05% + 46 uV)
For 100 readings averaged this gives +/-(0.05% + 39 uV)
Similar formulas can be derived for the other ranges using this form and the data book numbers.
