Note 1)
For -M (fixed SI unit)
Does not perform mode
switching even if the
button is pressed during
operation.
Initial setting: Sets the
display mode (real-time
flow rate/accumulated
flow), unit mode, and out-
put mode (non-inverted/
inverted).
Auto preset
Can perform fine adjust-
ment of data which is
automatically set with
the auto preset.
Press the SET button for 1 second or more.
Since the display will change from to
or , release the SET button after
it has changed.
