4-3. Setting items

[F1] Indication/output
In the indication/output, "forward flow (d.F.)" measurement or "forward/reverse flow (d.r.F)"
measurement is selected.
When the "forward flow" measurement is selected, the "forward accumulated flow volume (Total)"
or the "accumulated flow volume (Trip)" can be indicated on the main display by button operation.
When the instantaneous flow-rate is set with the analog output (4-20 mA), 4 mA becomes zero
flow-rate.
When the "forward/reverse flow" is selected, the "forward accumulated flow volume (Total)" or
"reverse accumulated flow volume (Total)" can be indicated on the main display by button
operation. The trip function cannot be used. When the instantaneous flow-rate is set with the
analog output (4-20 mA), 12 mA becomes the zero flow-rate.
See "4. Description of operation of display section" about the button operation.
[F2] Analog output FS (Full Scale) flow-rate
This function sets a full scale flow-rate value when the instantaneous flow-rate is set with the
analog output. On delivery from factory, the flow-rate value shown in the Table 3-1 or Table 3-2 is
set. When in use with the NORMAL conversion set to "With (ON)" set a NORMAL conversion
value.
[F3] State of contact output
Select "Normal open (n. OP)" or "Normal close (n. CL)."
Set this to "Normal open" in case of using a battery-powered signal receiving device.
[F4] Contact output
Select the output signal of open drain output 2 from "pulse output (reverse flow) (PULS),"
"main unit aberration output (Err)," "upper/lower limit flow-rate alarm output (AL)," and
"electronic statement output (COdE)."
"Main unit aberration output (Err)" outputs signals when one of the following occurs: ultrasonic
measurement aberration, pressure measurement aberration, temperature measurement
aberration, battery voltage reduction (for the built-in battery version only), and elapse of 11
years.
[F5] Lower limit alarm flow-rate
Use this to set the lower limit alarm flow-rate (5 digits) as the lower limit flow-rate value for the
upper/lower limit flow-rate alarm.
* This is the judgment value for flow-rate lower limit alarm output of open drain output 2.
[F6] Upper limit alarm flow-rate
Use this to set the upper limit alarm flow-rate (5 digits) as the upper limit flow-rate value for the
upper/lower limit flow-rate alarm.
* This is the judgment value for flow-rate upper limit alarm output of open drain output 2.
[F7] Alarm judgment value hysteresis width
With regard to the flow-rate value defined for the upper/lower limits of the upper/lower limit
flow-rate alarms, a hysteresis width range (4 digits) is defined for the alarm judgment value as
the range of flow-rates for terminating the alarm.
*This is the judgment value for flow-rate upper/lower limit alarm output of open drain output 2.
