Window comparator mode
● In this mode, the ON / OFF state of the comparative output is controlled with a flow rate in the set range.

Note: Hysteresis of the window comparator mode is approx. 1% F.S. (factory setting). The hysteresis can be changed
in the range of approx. 1 to 8% F.S. For details, refer to "Hysteresis setting" in "

● Take care that if fluid flows in the direc-
tion opposite to the set flow direction,
the integrated pulse is outputted as well.

RUN MODE
● I n this mode, flow rate display mode, confirmation of the set value, peak / bottom
hold function and key lock function are available.
In the flow rate display mode, color of the digital display changes in green or red
in conjunction with the comparative output. The color of the main display can be
changed in conjunction with the comparative output 1, while the color of the sub
display can be changed in conjunction with the comparative output 2.
For setting color of the digital display, refer to "Display color setting" in "
Flow rate display mode
● Either instantaneous flow rate or integrated flow rate can be indicated on the digital display.
● The integrated value can be reset by key operation or external input while the in-
tegrated flow rate is indicated. (Note 1)
● At the instantaneous flow rate display, 4-digit instantaneous flow rate value is indi-
cated on the main display, while the flow direction is indicated on the sub display.
● When setting flow direction to bi-direction or one-side forward direction, if fluid flows in
the direction opposite to the forward direction display on the main body, the flow rate val-
ue is indicated negatively. In case of one-side reverse direction, if the fluid flows in the
same direction to the forward direction display, the flow rate value is indicated negatively.
● At the integrated flow rate display, 7-digit integrated flow rate value is indicated on
the main display and the sub display.
● When setting flow direction to bi-direction, if fluid flows in the direction to the forward di-
rection display on the main body, the integrated value will be counted up. While if fluid
flows in the opposite direction, the integrated value will be counted down. Further, in case
of one-side forward direction and one-side reverse direction, if fluid flows in the direction
opposite to the set flow direction by mistake, the integrated value will be counted down.

Notes: 1) When resetting the integrated value, first set to the integrated value reset input function, then conduct key operation or
input an external signal. For setting the integrated value reset input function, refer to "CH2 setting" in "
2) The integrated value will be reset when the power is supplied again at the integrated flow rate display.
Confirmation of the set value
● The threshold value of the comparative output 1 and the output mode can be checked
while holding down UP key when the flow rate is indicated. Meanwhile, the threshold
value of the comparative output 2, the output mode and the integrated value reset input
function can be checked while holding down DOWN key when the flow rate is indicated.
