Note: If you want to stop a recording before it has run the full term, click on the Stop
Logging rates can be set from 50,000 samples per second (20 s interval) for capturing fast moving
data) to 1 sample an hour (for long term experiments).
Scope
The data from the sensor is redrawn continuously on the screen in a simple oscilloscope
type display.
Click on the Start icon
continuously on the screen until you click on the Stop icon
Note: Scope is not available when the User level is set to Level 1.
Timing
Timing is used to allow students to study Time, Velocity, Acceleration, Momentum and
Kinetic Energy relationships using switch-type (digital) sensors such as Light gates.
Sensors must be connected to either input 1:A or inputs 1:A and 2:B.
A recording wizard will open with the options available to select before recording data. (The availability
will depend on the level you have selected to work at). When the selection has been made, click on
Finish.
Click on the Start icon
the digital sensors.
Open
Use to load a previously saved data file. Locate the correct EasySense file (.SSL) and
select OK. See page 11.
Interface
Use to connect VISION as an interface controlled by the EasySense software on the PC
computer. See page 9.
Apps
Use to open or manage other applications available on VISION e.g. the Periodic Table,
Calculator, Bluetooth and WiFi. See page 13.
Smart Q Sensors
Smart Q Sensors are each equipped with a sophisticated microprocessor that greatly improves the
sensor's accuracy, precision and consistency. The auto-identification circuitry simplifies set up
procedures and allows for greater flexibility when logging data.
The four inputs on the top edge of VISION may be used with analogue and digital sensors. Both will
be recorded side by side during logging operations.
Sensor inputs 1 and 2 are dual labelled as A and B. These inputs
are for Timing operations when digital sensors must be
connected to either input 1:A or input 1:A and 2:B.
Four sensor leads have been provided to connect Smart Q
Sensors to the shaped input sockets on VISION.
