* Noise rejection is the ability to reject unwanted signals, or noise.
• Normal mode voltages are AC signals that can cause inac-
curate DC measurements. NMRR (Normal Mode Rejection
Ratio) is a measure of the ability to filter out these signals.
• Common mode voltages are signals present at the COM
and + input terminals, with respect to ground, that can
cause digit rattle or offset in voltage measurements. CMRR
(Common Mode Rejection Ratio) is a measure of the ability
to filter out these signals.
