The specifications apply to the extension plug as of version 3, delivery date from October 2017.

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
3
and assumes that the plug is recognized by the
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.
