Time of Flight Pad<\/a> (TOF-VPL<\/nobr>)
\nSpecifications and User Guide<\/a><\/p>\n

TROUBLESHOOTING
\nPrimary Tests:
\n– When used with a Vernier Projectile Launcher, make certain that the Time of Flight Pad is connected to the “Accessory” or “Ext. Switch” port on the launcher.
\n– When used with a Go Direct Projectile Launcher, make certain the Time of Flight Pad is connected to the “Accessory” port on the launcher.
\n– Set the data-collection mode to end after six events or set the projectile launcher mode to use the Time of Flight Pad.
\nTest data collection by tapping Collect.
\nPlace a finger across the aluminum barrel of the Launcher, and remove your finger to generate an event pair.
\nPlace and remove your finger a second time to generate a second pair.
\nThen press a finger firmly on the pad and release.
\nThis will generate a third pair of events.
\nDisplay the data table to see the times corresponding to the six events.
\n– Does the Vernier Projectile Launcher or Go Direct Projectile Launcher work as expected when the Time of Flight Pad is not attached?
\n– Do you have power to the launcher?
\nThe Vernier Projectile Launcher requires power from a interface or LabQuest®<\/sup> Power Supply<\/a> (LQ3-PS<\/nobr>).
\nGo Direct Projectile Launcher requires power from a USB power outlet, USB power brick, or active USB port on a device.<\/p>\n

Secondary Test:
\nVerify the projectile strikes the pad approximately in the center to ensure a solid registry of the impact.<\/p>\n

Note that the pad has a timer set so that the unblock event is about 1 s after the block event, regardless of how long the pad is compressed.<\/p>\n
