*1. The pressure precision is defined based on the values measured in the ordinary temperature environment (approx. 23°C)
      using water at the ordinary temperature (approx. 23°C).
*2. Even instantaneous pressure fluctuation such as water hammer must be within the withstand pressure.
      If instantaneous pressure fluctuation is expected, use the throttle included in the package.
*3. If the pipe temperature exceeds 70°C, do not contact any cables with the pipe.
*4. The maximum actual response time has error of 1 ms when the set response time is 3 to 10 ms, 5 ms when it is
      11 to 100 ms, and +5% when it is 101 ms or more.
*5. The pressure repeatability is the error of the detection point when pressure is applied repeatedly in the ordinary
      temperature environment (approx. 23°C) using water at the ordinary temperature (approx. 23°C) in the rated pressure
*6. The ambient temperature characteristics are prescribed based on the value measured using oil as applying a pressure
      value of 50% of the maximum rated pressure.
*7. The temperature monitoring precision is prescribed based on the value measured using water.
      Temperature measurements are affected by both of the temperatures, the medium and the piping.
      Temperature measuring elements are installed on the back surface of the piezoelectric element (inside the product) and
      used to measure the temperature. It might take long for the measured value to get stable according to the heat
      transmission speed.
*8. Do not connect CH 2 (pin 2) with the IO-Link master unit in analog current output mode. Otherwise, the unit might fail.
