Answer Posted / k.sreenivasan
Go to the field and check the local indication in the
transmitter.(normally it is in either engg. units or as
percentage)
If it is zero ,then the problem is in the sensor or
terminal connection, because most of the current generation
transmitters are highly accurate and have longer stability
periods.
Suppose local reading is ok,then check the DCS analog input
card for any fault condition and clear it.Normally this
situation is rare.
