I have a Fluke 8846A and I want to make a frequency measurement with an error less than 1 mHz. I'm having trouble interpreting the manual as to calculate the error of a 120V 60Hz measurement.
On page 1-12, the 100V, 10Hz-20kHz, 1 year (its calibrated every year) is states the error is 0.06% of the measurement + 0.03% of the range.
Say I measure 60Hz exactly, does that mean my error is (60 Hz * 0.0006 + 0.0003 * (20 kHz - 10 Hz)) = 6.033Hz? That seems too high of an error though.
