• When the display resolution lowers and the wobbling of momentary
flow rate increases in the low flow domain of the differential pressure
flow meter, the domain (below the set value) will be forcedly indi-
cated as zero by means of the
low-cut for momentary flow rate.
Moreover, the analog output has a fixed value of 4mA at the zero
point. For setting of low-cut, input the percent value over the maximum
display span. Its range is 0 to 30%F.S. and the decimal point position
can be set up to one digit after decimal point as fixed point.

(2) Analog output
The zero point (4mA) and span point (20mA) of analog output can
be set in the range of 0 to 110%F.S. of the maximum display span
(0 to maximum momentary flow rate). The span between the zero
point and the span point in this analog output is the momentary
flow rate display span.
(3) Integrated volume
• The units of integrated volume include two standards: Time
factor and flow rate volume factor.

• The number of digits of integrated volume display is a
maximum of 6 figures (999999); the display will return to 0 once
the maximum reading has been met.
• The zero reset of an integrated volume is executed by pressing S key
for more than 3 seconds and displaying "cLr" (clear) for 2 seconds.

• As backup in case of POWER OFF , the integrated volume value
is stored in the nonvolatile memory for every hour. After power re-
turns, integration starts from the integrated volume value stored in
the memory.
