왎 Display colour
The display colour can be selected for each
output condition. The selection of the dis-
play colour provides visual identification of
abnormal values. (The display colour de-
pends on OUT1 setting.)
왎 Setting of response time
The response time can be selected depending
on the application. (1 second for default setting)
The flickering of the display can be reduced
by setting the response time slower. If you
need faster detection of the problem such
as leakage of tip cooling water for welding
gun, switch output or analogue output can
be faster by setting the response time fast-
er. In this case, widen the hysteresis to
prevent chattering of the switch output.
왎 Output operation
The output operation can be selected from the following:
Output (hysteresis mode and window comparator mode) correspond-
ing to instantaneous flow rate, output corresponding to accumulated
flow, or accumulated pulse output
Note) At the time of shipment from the factory, it is set to hysteresis mode
and normal output.
왎 Forced output function
Output is turned ON/OFF compulsorily when starting the system or
during maintenance. This enables confirmation of the wiring and
prevents system errors due to unexpected output.
For the analogue output type, the output will be 5 V or 20 mA for ON
and 1 V or 4 mA for OFF.
∗ 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.
왎 Accumulated value hold function
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 element is 1 million access cycles. Take this
into consideration before using this function.
왎 Switching of flow direction
Flow direction can be changed after installation.
왎 Selection of display on sub screen
The display on the sub screen in measuring mode can be set.
