To Calibrate the Motion Sensor
Note: Calibration is usually not necessary. The following steps require
DataStudio.
1. In the Experiment Setup window, click the Motion Sensor
tab.
2. Place a target object at a standard distance in front of the
Motion Sensor (typically about 1 m).
3. Precisely measure the distance from the Motion Sensor's
transducer to the nearest point of the target object.
4. Enter this distance (in meters) in the Standard Distance
field.
5. Click the Set Sensor Distance = Standard Distance button.
DataStudio adjusts the speed-of-sound constant that it uses to cal-
culate distance.
Equipment Mounting
Mount the Motion Sensor as illustrated on a vertical rod (a) or a
horizontal rod (b).
Integrated clips allow it to be attached to the end of a dynamics
track (c).
A threaded hole in the bottom of the unit (d) is provided for
attachment to the PS-2546 Magnetic Bracket (e), the ME-6743
Cart Adapter (f), and other 1/4-20 threaded mounting devices
such as a camera tripod.
To protect the Motion Sensor from being hit by an object, use a
device such as the SE-7256 Motion Sensor Guard (g) or
ME-9806 bracket with a rubber band (h). The Motion Sensor can
“see through” a wire screen or rubber band placed close to the
transducer.
