Data transmitted from the MultiLogPRO while the graph is frozen, is
stored onto the PC but is not displayed.
3. Click on the end of the curve and move the mouse according to your
predictions. Click to draw a straight-line segment. Move the mouse
again and click where you want the second segment to end, and so
on.

The Timing Wizard

1. Overview

The Timing Wizard enables you to easily measure and calculate many types of time
events, including velocity and acceleration with one or two photogates.
Connect one photogate to input 1 or connect two photogates to input 1 and input 2 in
MultiLogPRO and perform the experiment. The Timing Wizard will then guide you
through the analysis.
With the Timing wizard you can measure sequences of time events at gate one
and/or at gate two, or time events between the two gates. MultiLab can then
calculate the velocity and acceleration. Special options make it easy to measure
velocities in collisions and the time period of a pendulum or any other oscillating
body.
The Timing Wizard can handle multiple events. For example, when a body is
crossing a photogate several times, applying the Timing Wizard will result in a series
of measurements that match the number of crossings.
Note: If you wish to measure fast timing events with photogates only use
MultiLogPRO's accurate timer module (see page 35).
