Timing
Timing is used to set up and store simple time and speed measurements using digital switch type sensors.
Connect either one sensor to Input 1:A or two to Input 1:A and 2:B before selecting Timing. The options
available will depend on whether one or two sensors are connected.
For V-Log to be able to calculate speed or acceleration you will need to enter a measurement of the
apparatus used in the experiment e.g.
For Speed A to B this is the distance between the sensor connected to input A and the sensor
connected to input B (0.10 m to 6.00 m in steps of 0.10 m).
For Speed at A, using a single interrupt card, select the width of the card that will pass through the
Light gate (30 mm to 120 mm).
Upon completion of a timing event the measurement will be displayed on the LCD display.
Timing options are:
