PF-F/PFU Series
Functions and operations for monitor
Measurement mode
Note) Integrating ow is displayed in integers.
In 10 seconds, the light goes from blinking to 
steady and the display automatically returns to 
the instantaneous ow rate display.
Holding down for 2 seconds conrms the setting: the blinking light will 
change to a steady light and the display will constantly show an 
integrated value. As the measurement setting is retained even if the 
power is turned OFF, resetting is not necessary.
To return to the instantaneous ow rate display, hold down for 2 seconds again.

·   Hold down the Shift/Up keys together for 10 
seconds to clear the integrating value.
·  Set the h (hysteresis) value with the Shift/Up keys.
·  Set the H (High) value with the Shift/Up keys.
·  Set the L (LOW) value with the Shift/Up keys.
· Set the parameter with the Up key.
Note)   L, H and h are not displayed if parameter 2 is 
selected. Refer to the instruction manual for 
details.
Note)   In the example below, P (parameter) is set to 0, 
L (Low) to 100, H (High) to 200, and h 
(hysteresis) to 10 L/min (normal).
