Special Functions
CMRR
(Common Mode Rejection Ratio)
DC voltage shares can occur at the
COM as well as at the voltage input
socket with reference to ground.
The Multimeter series Hexagon is
equipped with a CMRR mode.
Hereby undesirable DC voltage sha-
res are suppressed which could
cause digital jumps or offsets during
voltage measurements.
The CMRR mode for the Hexagon
series is specified to >60 dB at 0...60
Hz in AC voltage ranges and >120 dB
at 0 Hz, 50 Hz and 60 Hz in DC volta-
ge ranges.
