RTD output values
We have RTDs connected to a generator. However, some of the RTDs tends to give a much higher value and goes down at a very low value. This seems to happen in fixed intervals. What could possibly be the problem?

The result was different temperature values proportional to the distance of each RTD from the PLC. Sent from my BlackBerry® wireless handheld
