< 4 mA.
The calibration of the current
output is incorrect. Execute the calibration if you have
authorized access or contact
KROHNE Service Centre**.
An error has occurred. This happens in case the range 4-
20 mA / error 22 mA is selected.
Check the status of the device by
selecting the marker window (F8)
or enter the Watch status (4.0)

value drops to a value between 4
and 20 mA, and goes immediately
back to 22 mA, contact your
KROHNE Service Centre**.
The value at the current
output does not correspond
to the value at the display
(PC STAR 2 or HART
®
communicator).
The current output settings
are incorrect. Check the current loop and the
