● Single-acting - In one direction the output gauge should reach full supply pressure and
hold when the buttons are released. When going in the opposite direction, the output
gauge should go to zero psi. While it is going to zero, air pressure should be blowing out
of the exhaust port.
● Double-acting – The two output gauges will indicate opposite pressures from each other,
when at each end-stop position. While the top gauge is pressurizing the bottom gauge
should be exhausting. The gauge that is pressurizing should reach full supply and hold
when the buttons are released. Device should only exhaust while the unit is moving. At
rest, no air should be blowing out of the exhaust port.
