This is the inlet for atmospheric pressure. An R1/4 fitting can be used for connection. When
connecting a fitting, use a sealing material such as sealing tape to prevent leakage.

Caution
• Do not allow any foreign matter such as the end of the sealing material to enter inside the pressure
port. If foreign matter gets inside, measurement errors or failure could result.
• When installing the fitting, do not overtighten it as this could result in failure.
Be sure to tighten it within the tightening torque range.
