Check the polarity if it is in the right direction.
Check the Power line.
Check the Power voltage.

.
Check the PV reading.
Check if the applied PV is in the measuring range.
Check if the applied PV is in the nominal sensor range.
Check the displacer placement.
The signal output doesn’t
change at all.
Check if it is the Fixed current mode.
Check the displacer placement.
Erratic reading for
PV(Hunting)
Check the displacer placement.
Check the damping time.
Transmitter is turned off
when the current output
rises.
Check the power supply / Load relation.
The signal output doesn’t
correspond to PV.
Perform a D/A trim.
PV Zero is not correct
Check displacer placement.
Perform PV zero setting.
