Switching mode
Note:
1.Maintain intervals more than 3% F.S. between two setpoints during window operation.
Hysteresis of 1% F.S. is provided on each ON and OFF sides automatically.
2.Maintain intervals more than 1% F.S. between two setpoints when hysteresis operation.
3.If the differential between above 2 setpoints is not satisfied, it may result in not operated
or unstable operation. If a switch is activated in unstable flow rate state such as a fluid
pulsation, etc., unstable operation may be provided. In this case, maintain the difference
between two setpoints satisfactorily, use the product after checking that switching is
stabilized.
4.In operation waveform, left side shows minus side, while, right shows plus side.
5.If waveform pattern is decided, magnitude of ON and OFF setpoints is decided, and the
reverse magnitude is not allowed. However, in this product, operation with specified
operation pattern has precedence over all things. When the two setpoints are inputted, the
magnitude is identified automatically, processing the proper identification as ON and OFF
setpoints. As result, even if ON and OFF setpoints are inputted reversely, re-recognized as
correct ON and OFF setpoints, always operating with the specified operation pattern.

Maximum and minimum values indicated with flow rate value can be read during the specified period. Use this function when checking
instantaneous flow rate change. Also, peak hold operation never affects the basic function of this product such as switching and flow rate
