Note 1) Value without digital filter (at 0 ms)
Note 2) If the applied pressure fluctuates around the set value, the hysteresis must be set to a value more than the amount of fluctuation or chattering will occur.
Note 3) This setting is only available for models with the unit selection function. Only MPa or kPa is available for models without this function.
Note 4) The response time indicates when the set value is 90 % in relation to the step input.
