– 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.
– When used with a Go Direct Projectile Launcher, make certain the Time of Flight Pad is connected to the “Accessory” port on the launcher.
– Set the data-collection mode to end after six events or set the projectile launcher mode to use the Time of Flight Pad.
Test data collection by tapping Collect.
Place a finger across the aluminum barrel of the Launcher, and remove your finger to generate an event pair.
Place and remove your finger a second time to generate a second pair.
Then press a finger firmly on the pad and release.
This will generate a third pair of events.
Display the data table to see the times corresponding to the six events.
– Does the Vernier Projectile Launcher or Go Direct Projectile Launcher work as expected when the Time of Flight Pad is not attached?
– Do you have power to the launcher?
The Vernier Projectile Launcher requires power from a interface or LabQuest 2 Power Supply.
Go Direct Projectile Launcher requires power from a USB power outlet, USB power brick, or active USB port on a device.
Verify the projectile strikes the pad approximately in the center to ensure a solid registry of the impact.
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.
The top surface of the Time of Flight Pad is 2.7 cm from the bottom surface.
