CAUTION
Do not operate the console keys using a sharp object such as a mechanical pencil or

„  Basic operation
Basic operation is used to change the display to instantaneous flow rate (PV), flow
set value (SP), totalized flow value, or valve amperage.
Normally, when the power is turned ON, the instantaneous flow rate is displayed
in basic operation mode. When this is the case, operating the
DISP key
changes the
contents of the 7-segment display as described below.

L/min lamps
light, and the
instantaneous flow rate is indicated on the display.
Handling Precautions
•
When the operating mode is set to fully closed, and the flow rate is zero,
and when the operating mode is switched to the control mode or fully
open mode, the operating mode (
OFF
/
