Contact the nearest
Yokogawa office or
service center.
Check the followings:
• Mix of the signal, power
supply, excitation and
other cables
• Stray currents in the
measured fluid
• Incorrect grounding
Contact the nearest
Yokogawa office or
service center.
Change settings.
Fill the flow tube with
fluid or clean the flow
tube inside.
Change settings.
Contact the nearest
Yokogawa office or
service center.
