The Photogate is for motion timing. It can time objects that pass through the gates or as a laser gate outside of the gates. It can also be used to time motion in any of these states: • Pulse • Pendulum • Gate and pulse • Gate state only Setting the Drop Counting Collection Mode Select the Drop Counting collection mode only when using the Vernier Drop Counter optical sensor. Collecting Data After you set up the sensor and select the collection mode, start collecting the data for the experiment. The collection mode determines the steps required for collecting data. If you are in Meter View when you start data collection, the Vernier DataQuest™ application changes to Graph View and begins recording sensor data. The graph updates to show the data as it is collected.

•
Pulse

•
Gate and pulse
•
Gate state only
Setting the Drop Counting Collection Mode
