Vernier Projectile Launcher (VPL)
Specifications and User Guide

TROUBLESHOOTING
– Primary Test: Verify that the Projectile Launcher is powered from either an interface via the photogate cable or from AC power via a LabQuest Power Supply.

– Secondary Test: Check that the hand pump is securely attached to the valve on the launcher. Watch the pressure gauge on the hand pump as you pressurize the system, and verify that the system is holding the pressure and that there are no pressure leaks.

– Additional Test: Double-check that you continue to hold the “arm” button while you press the “launch” button. The two buttons must be engaged simultaneously to launch the projectile.
