AI 810 reading fluctuation
II have an AC450 connected to AF100 network with redundant CI522A CI820 (2.2/3) and AI 810.
suddenly at one AI810 one signal fluctuate from 5_10 %from its normal reading.so I changed the AI810 ,Transmitter , check the whole wiring and injected 4_20 MA directly to the AI 810 after removing the cable but the problem still exists.
So I connected the transmitter to another spare channel at the same AI810 and now it's OK.
So my question what is the problem of the deflected channel?

has the replaced AI 810 also gave fluctuation on same channel ?
I would say you have to record the instrument reading over a period of time and check the results.. before declaring channel error!!
