6.10.6.2 Channel Cross-Talk
Conditions: sinusoidal form infeed on a channel without overload, AC
measurement on neighboring channel, integration time 1 s.
Table 6-34:
Cross talk dampening
Cross talk dampening on channels of the same potential groups in dB at
f = 50 Hz
Table 6-35:
Cross talk dampening
Cross talk dampening on channels of the same potential groups in dB at
f = 500 Hz
The cross-talk dampening on a neighboring channel of another potential
group is greater than 120 dB in all measurement ranges (f = 50 Hz or
500 Hz).

a)
b) 3Sigma
max
represents the maximum of the 3Sigma values of all 10 input channels.
The 3Sigma
max
value of an analog input are determined from 50 measurement values.
