Chapter 5. ADVANCED OPERATION
The flow rate range can be reduced to a level of 99 % down to 10 % of the standard range using the flow rate range
setup (
C-24
or
C-25
). However, the minimum control flow rate is the same as for the standard range. As the range
is reduced, the setup and display resolution levels are improved as described in the table below.

Handling Precautions
•
Even after flow rate range is changed, the accuracy specifications are the
same as for the standard range. (The full scale designated by % FS shows the
numeric value of the standard range.)
•
Even though the flow rate range is changed, the minimum control flow rate is
the same as for the standard range.
•
The scaling of the analog input/output is automatically changed to ensure
that the modified flow rate range is FS.
