Function Details
Delay time setting
The time from when the instantaneous flow reaches the set value to
when the switch output operates can be set. Setting the delay time
can prevent the switch output from chattering.
The total switching time is the switch operation time and the set delay
time.
(Default setting: 0 s)
Output operation
The output operation can be selected from the following:
Output (hysteresis mode and window comparator mode) correspond-
ing to instantaneous flow, output (accumulated output and pulse out-
put) corresponding to accumulated flow, error output, or output OFF
* At the time of shipment from the factory, it is set to hysteresis mode and normal output.
Display color
The display color can be selected for
each output status. The selection of the
display color provides visual iden-
tification of abnormal values. (The
display color depends on OUT1 setting.)
Reference condition
The display unit can be selected from standard condition or normal
condition.
Standard condition: Flow rate converted to a volume at 20°C and 1 atm (atmosphere)
Normal condition: Flow rate converted to a volume at 0°C and 1 atm (atmosphere)
Display mode
The display mode can be selected from
instantaneous flow or accumulated flow.
Display
Display OFF mode
This function will turn the display OFF. In this mode, decimal points
flash on the main screen. If any button is pressed during this mode,
the display reverts to normal for 30 s to allow the flow, etc., to be
quickly checked.
Setting of a security code
The user can select whether a security code must be entered to
release the key lock. At the time of shipment from the factory, it is set
such that a security code is not required.

Response time (Digital filter)
The response time can be selected to suit the application.
(Default setting: 1 s)
Abnormalities can be detected more quickly by setting
the response time to 0.05 s.
The effects of fluctuation and the flickering of the display
can be reduced by setting the response time to 2 s.
External input function
This function can be used only when the optional external input is
present. The accumulated flow, peak value, and bottom value can be
reset remotely.
Accumulated value external reset: The accumulated flow value is reset via external
input signal.
In accumulated increment mode, the accumulated
value will reset to and increase from zero.
In accumulated decrement mode, the accumulated
value will reset to and decrease from the set value.
* When the accumulated value is stored to memory, every time the
accumulated value external reset is activated, the memory (EEPROM) will
be accessed. Take into consideration that the max. number of times the
memory can be accessed is 3.7 million times. The total number of external
inputs and the accumulated value memorizing time interval should not
exceed 3.7 million times.
Peak/Bottom value reset: The peak value and bottom value are reset.
Forced output function
The output is forced ON/OFF when starting the system or during
maintenance. This enables confirmation of the wiring and prevents
system errors due to unexpected output.
For the analog output type: When ON, the output will be 5 V (or 10 V
when 0 to 10 V is selected) or 20 mA, and when OFF, 1 V (or 0 V when
0 to 10 V is selected) or 4 mA.
* Also, the increase or decrease of the flow will not change the ON/OFF
status of the output while the forced output function is activated.
Accumulated value hold
The accumulated value is not cleared even when the power supply
is turned OFF.
The accumulated value is memorized every 2 or 5 minutes during
measurement and continues from the last memorized value when
the power supply is turned ON again.
The life time of the memory device is 3.7 million access times. Take
this into consideration before using this function.
