Data are collected at a rate that is pre-set in an experiment file or an auto-ID sensor.
If you want to change the default settings, choose Data Collection from the Experiment Menu.
Set the Mode to Time Based to collect data over time.
To set the Length of the experiment, select the time and time units that are most appropriate for your collection - milliseconds (ms), seconds (s), minutes(min), or hours(hr). The Time axis of the graph will be modified to reflect the experiment length.
If Sample At Time Zero is checked, a data point will be taken immediately when data collection starts. If not, the first data collection point will be collected based on the data collection rate. For example, if the data collection rate is set to 1 sample/second, the first point will be collected 1 second after data collection has been started.
If Continuous Data Collection is checked, data collection will continue beyond the data collection length that has been set for the file and will keep going until the Stop button is clicked. Data will be collected at the data-collection rate that is set up in the file.
You may enter the desired number of samples per time to be collected. If you enter a value for the samples/time, the time/sample value will auotmatically be updated. You can also enter a value of time/sample and Logger Lite will update the samples/time value. For example, if you enter a value of 5 samples/second, the value of seconds/sample will be updated to 0.2 sample/second.
Note: Logger Lite's maximum rate depends on the interface. The following rates are the maximum rates for each interface.
- Go! Temp: 2 samples/sec.
- Go! Motion: 25 samples/sec.
- Go! Link: 200 samples/sec. (depends on the sensor being used)
- LabQuest: 100,000 samples/sec. (depends on the sensor being used)
- LabPro: 50,000 samples/sec. (depends on the sensor being used)
The total number of points that will be collected is shown here. For example, if you choose a length of 180 seconds, a sampling rate of 1 samples/s, and check Sample At Time Zero, you will collect 181 points.
