Note
•
The setup and display resolutions described above can be improved by reducing
the flow rate range using flow rate range setup
C-24
or
C-25
.
A still higher resolution can be set using the analog setup (
C-03
= 1). For more
information, 5 - 4 Flow Rate Range Change Function and Settings and
Display Resolutions After Change of Range (P.5-17).
