Span flow velocity setting is 11 m/s or more
Span flow velocity setting is 0.05 m/s or less
Mass units have been selected for Base
Flow Unit but density is set to zero.
Measure Mode is set to Enhanced DF without
selecting an optional code HF1 or HF2.
A value of 3000.1 mm or more is set for Nominal Size.
The condition in Adhesion detection level,
Level:1
IT1 CLOCK_PER set value is smaller than excecution period
IT2 CLOCK_PER set value is smaller than excecution period
RANGE_HI>RANGE_LO is not satisfied
Check XD Scale,Density Unit,Mass Flow Density
Check Measure Mode of TB
Check Nominal Size,Nominal Size Unit
Check Adhesion Level1 to Adhesion Level 4
Check Clock Period,Period of Execution
Check Clock Period,Period of Execution
Check Range Hi and Range Lo of AR
Check XD Scale of AI
Schedule FB, or check LAS communication
Check signal cable and grounding
Fill flow tube with fluid
Clean electrodes
Check the flow rate and setting value
Check the flow rate and setting value
Check the setting value
Check the setting value
Check software download error code
Cut the power and check coil & EX cables
