Accelerometer Type and Measurement Axes:
The accelerometer is a dual axis, 18 G,
cantilevered beam, MEMS device and is
located on the center post of the end node.
The accelerometer is used for sensing
mechanical vibrations. The two axes of
measurement are referenced in Figure 7.

Data Collection Intervals:
Five different data collection intervals are available for use with this
product. For example, a 15-second data collection interval denotes that
once every 15 seconds the end node will activate and collect 4,096 data
points over an approximate one second period. Next, it will parameterize
and transmit data prior to returning inactive. A 60-second data collection
interval denotes that once every 60 seconds the end node will activate
and collect 4,096 data points over an approximate one second period.
Next, it will parameterize and transmit data prior to returning inactive.
The data collection interval and environmental conditions will determine
the life of the battery. The factory interval setting is every 15 seconds. It is
recommended that you initially retain the factory setting for network
configuration then switch to a longer data collection interval to conserve
battery life.
