Flow rate measuring unit confirmation
This function allows to confirm the accumulated flow rate
when real-time flow rate is selected and to confirm the
real-time flow rate when accumulated flow rate is selected.

A current of more than
80mA is flowing to OUT1
A current of more than
80mA is flowing to OUT2.
The setting data has
changed for whatever
reasons.
The flow rate is over the
flow rate measurement
range (for air only).
Check the load and wiring
for OUT1.
Check the load and wiring
for OUT2.
Perform the RESET
operation, and reset all
data again.
Reduce the flow rate until it
is within the flow rate
measurement range, using
an adjustment valve.
Key lock
This function prevents incorrect operations such as
changing the set value accidentally.
Accumulation clearance
This is to clear the accumulated value.
Initialization of setting (Only for series PF2A7
H)
This is to restore the setting to the initial state when
dispatched from the factory.
