6. Click an option to select the measuring method
7. If required enter the body’s width in mm (an integer between 0 to
59), or the distance between the gates in cm (an integer between 0
to 99) in the appropriate edit box (in velocity and acceleration
measurements only)
8. Click Start to enter to a timing standby mode
Timing begins each time a body blocks the photogate in input 1 and ends when
unblocking the photogate in input 1 or input 2 (according to the event method).
MultiLab displays the results in a bar graph and in the table.
You can repeat as many measurements as you want. After each event MultiLab adds
the results as a new bar in the graph and as a new raw in the table.
To exit the timing mode click Stop on the main toolbar.
2. Measuring Methods
The Timing Wizard offers you various methods of analyzing the different
measurements. In some measurements you will be asked to enter the dimension of
the moving body, or the distance between the two photogates to allow for the
calculation of velocity and acceleration.
The methods depend on the selected measurement:
Time
• At one gate
Measures the time it takes the
body to cross the photogate
(between blocking and
unblocking the infrared beam)
