Select the Data Collection Mode
For each sensor from Vernier, DataMate loads a default experiment (data collection
mode) appropriate for the sensor. The default data collection mode for all sensors is
Time Graph (collecting data points at a predetermined rate). For a description of
each of the data collection modes, see Select Mode screen on page 27.
Note: If you close the DataMate program and then re-open it, the mode setting will be the
same as when you closed it. However, if you exit DataMate in some other manner, the mode
setting may be different when you re-open it. Or, you may open DataMate and find mode
and sensor settings that are “left over” from a previous experiment. In any case, press
‘
to return the mode and sensor settings to the default.
To change the data collection mode, follow the steps below.
