PART-7 TROUBLESHOOTING AND FAQ 

 

 

Troubleshooting 

The  ULTRA-E-F  ultrasonic  flow  meter  has  advanced  self-diagnostics  functions  and  displays 

any  errors  in  the  upper  right  corner  of  the  LCD  via  definite  codes  in  a  date/time  order. 

Hardware  error  diagnostics  are  usually  performed  upon  each  power  on.  Some  errors  can  be 

detected  during  normal  operation.  Undetectable  errors  caused  by  incorrect  settings  and 

unsuitable measurement conditions can be displayed accordingly. This function helps to detect 

the  errors  and  determine  causes  quickly;  thus,  problems  can  be  solved  in  a  timely  manner 

according to  the solutions listed in the following tables. 

Errors  displayed  in  the  ULTRA-E-F  are  divided  into  two  categories:  Table  1  is  for  errors 

displayed  during  self-diagnostics  upon  power  on.  “*  F”  may  be  displayed  on  the  upper  left 

corner  of  the  screen  after  entering  the  measuring  mode.  When  this  occurs,  it  is  necessary  to 

power  on  for  self-diagnostics  once  again  to  detect  and  solve  possible  errors  using  the  table 

below. If  a problem still exists,  please contact  the factory or the factory’s local  representative 

for assistance. 

Table  2  applies  when  errors  caused  by  incorrect  settings  and  signals  are  detected  and  are 

announced by error codes displayed in Window M07.
