Resulting cut-off frequency of combined analog and digital high pass (depending on input impedance / selected range)
Digital high pass for complete removal of residual offset: supported for selected amplifier types

Common mode rejection ratio (CMRR)
(in conjunction with amplifier UNI2-8, range 10 mV, with digital high pass activated)
This typical plot refers to extension plug version 3
system software. That will result in activation of a digital high pass, in addition to the usual analog input
high pass (AC coupling of signals with 12 V DC offset). Such firmware driven signal processing will remove
any remaining residual offsets.
