Data Collection Modes
EasyData has several modes that let you collect data automatically or
manually. The five most common modes are listed below.
In Time Graph mode, EasyData automatically collects a specific
number of samples at regular time intervals. You set the interval (in
seconds) and the total number of samples to collect. You can stop the
sampling manually, if you wish.
In Events with Entry mode, you capture samples manually for a set
of events that you define. For example, you might want to collect
Boyle's law data using a gas pressure sensor to sample pressure
readings for corresponding volumes of a container.
In Selected Events mode, you capture samples manually every time
is selected. For example, you might want to collect individual
temperature and pH readings along a stream bank at different
locations.
In Single Point mode, an averaged reading is collected for each data
collection. A consecutive reading is collected each time a new data
collection is started. This mode is ideal for environmental monitoring
such as stream temperature or pH.
In Rate mode, the rate of periodic data, such as heart rate or sound
waveforms, is calculated. This mode can be set to collect rate
readings in beats per minute (bpm) or Hertz (Hz). Only select sensors
support rate mode.
When you change an EasyData mode or setting, the change
remains in effect until you restore the default settings, or
connect a different sensor. If a new sensor is added, you have
the option of adding the new sensor and retaining the
previously set mode or restoring the mode to the default
settings.
