      Connect the three 1.5 V dry cell batteries' positive (+) lead to terminal 3, and the negative (-) lead to terminal 1.

    4. Connect the voltmeter's positive (+) lead to terminal 2, and the negative (-) lead to terminal 1.

    5. Measure the voltage according to the value(s) in the table below.

      Standard Voltage
      Tester Connection Condition Specified Condition
      2 - 1

      Refrigerant pressure:

      0.39 to 3.187 MPa (57 to 463 psi)

      		 1.0 to 4.8 V

      If result is not as specified, replace the pressure switch.
