1. Connect the continuity tester across the blade terminal and the metal case of the switch. With 0 psi pressure applied to the switch, the tester should indicate no continuity (switch open).
2. Gradually increase the pressure to the switch. As pressure increases through the range of 2.0/5.0 psi, the tester should indicate a change to continuity (switch closed). The switch should remain closed as the pressure is increased to 90 psi maximum.
3. Gradually decrease the pressure through the range of 2.0/5.0 psi. The tester should indicate a change to no continuity (switch open) down to 0 psi.
