Note 1) With the condition of no flow on the output side. Together with the set pressure, be sure to maintain a minimum differential pressure of 0.05 MPa for
models IR1000 and IR2000, and 0.1 MPa for model IR3000.
Note 2) Applicable only to air operated types IR2120 and IR3120.
Note 3) Indicates the linearity of the output pressure with respect to the input signal pressure.
Note 4) Air is normally being discharged to the atmosphere.
