If the sensor is
oriented with
the Y-axis
pointing down,
the
Acceleration
Y-Axis reading
is -1.0 g in Y.
See (3). If the
sensor is
oriented with
its the Y-axis
arrow pointing
up, the
Acceleration
Y-axis reading
is 1.0 g in Y. See (4)
If the sensor is
oriented with
the label
facing up, the
Acceleration
Z-axis reading
will read 1.0 g
in Z. See (5). If
the label is
facing down,
the reading is
-1.0 g in Z. See (6).
About the Measurement
This sensor has the over-sampling command capa
-
bility that can be used by the data collection soft
-
ware
Over-sampling
Over-sampling reduces noise, produces smoother
data, and improves the measurement resolution.
This effect is especially noticeable when very small
changes are measured. The degree of
over-sampling depends on the sample rate.
Maximum over-sampling occurs at slower sample
rates. To increase the degree of over-sampling,
lower the sample rate in the software.
Specifications
(*NOTE: Altitude reads zero for sample rate greater than 100 Hz)
Altitude
The Altimeter relies upon barometric pressure to
calculate altitude. As barometric pressure changes
with weather conditions, the altitude reading will
appear to change. During a period of high pressure,
for example, the altitude reading may be lower than
expected. However, the Altimeter will correctly
measure the change in altitude or height. If possible,
zero the sensor when it is located at the starting
position. If more than altitude change is required,
use the data collection software to create a
calculation of true altitude using a correction factor
based on the known altitude at the starting position.
