Snapshot
Snapshot mode enables you to capture sensor readings every time the enter button is pressed, rather
than at regular time intervals.
1.
Connect any plug-in sensors if required. If the display is turned off, press any button to wake up
the logger
.
2.
While in the main menu use the up or down buttons
▲▼
to scroll until the cursor is pointing at
Snapshot
. Press the enter button
►
to select.
3.
Each time you press the enter button
►
a reading will be taken from the sensors. The bottom line
of the LCD will display the number of samples taken so far.
If using more than 3 sensors use the
▲▼
buttons to view the current value from the sensors
while still logging.
Note:
If V-Log
goes into ‘sleep’ mode during logging, press any button to wake up the logger then press
►
to take a reading.
4.
When you have finished sampling press the stop button
to close the data set, then enter
►
to
confirm your choice.
The readings will be stored as a data set identifiable by the method and time and date the recording was
started i.e. Snapshot 09/05/12 16:12:43. At least 650 samples can be stored in one data set (the limit is
dependent on the number of sensors).
The contents of the data set can be

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).
