Effective noise is reduced by a factor of 10 for every 20dB of noise rejection (140dB reduces
effective noise by 10,000,000:1).
CMRR is rejection of undesirable AC or DC signal between LO and earth. NMRR is rejection of
undesirable power line related AC signal between HI and LO.

Factory calibration uncertainty represents traceability to
NIST. This uncertainty is added to relative accuracy
specifications to obtain absolute accuracies. The 200mV and
2V range uncertainties are equal to the uncertainty of the 2V
calibration source. The 20V, 200V, and 1000V range
uncertainties are equal to the uncertainty of the 20V
calibration source.
