1 Connect a 0 to 3000 PSI / 0 to 207 bar
pressure gauge to test port TP1 on the function
manifold.
2 Turn the key switch to Ground control. Pull out
the platform red Emergency Stop button to the
on position and pull out the ground control red
Emergency stop button to the on position.
3 To enter the pressure sensor calibration mode
