Calibrating the Acceleration Sensor
The Acceleration Sensor is factory calibrated and is
accurate to about 0.05 g or 0.5 m/s
2
. For most
experiments, no further calibration is required. However,
the following calibration procedure may be performed to
maximize the Acceleration Sensor's accuracy.
Maintaining the Direction of Sensitivity
The sensing unit of the Acceleration Sensor is oriented so
that the line of greatest sensitivity follows the arrow
indicating the direction of acceleration (Figure 2).
Experiments should be conducted with the arrow on the
label of the Acceleration Sensor oriented along the same
line as the direction of the acceleration to be measured.
1
Double click the Acceleration Sensor icon (
) in
the setup window of Data Studio then click the Cali-
bration tab.
2
In the Calibration dialog, enter 1.000 in the High
Value dialog box in the pop-up menu, and -1.000 in
the Low Value dialog box.
3
Place the sensor flat on a level surface with the arrow
indicating direction of sensitivity parallel to the
ground (Figure 3a) and press the tare button.
