Collecting Data

Select the Start button to begin collecting data.

PASCO Capstone

Connecting the Sensor to a Tablet or a Computer via Bluetooth

For PASCO Capstone, select 

Hardware Setup

 in the Tools palette. In 

Hardware Setup

 the sensors are 

ordered by proximity to the device. Select the address that matches the Device ID XXX-XXX number on the 
sensor. 

Select a display in the main window or from the 

Display

 palette. In the display, use the 

<Select Measurement>

 

menu to pick a measurement to be shown. 

Connecting the Sensor to a Computer with the Micro USB Cable

Connect the micro end of the included Micro USB Cable into the micro USB port on the end of the sensor. 
Connect the other end of the Micro USB Cable to a USB port on the computer, or into a powered USB hub 
connected to the computer.

In PASCO Capstone, select a display in the main window or from the 

Displays

 palette. In the display, use the 

<Select Measurement>

 menus to pick the measurement to be shown.

Collecting Data

Select 

Record

 to begin recording data.

Troubleshooting the Sensor 

If the sensor loses Bluetooth connection and will not reconnect, try cycling the ON button. Press and briefly 

hold

 the button until the status LEDs blink in sequence, and then release the button. Start the sensor in the 

usual way.

If the sensor stops communicating with the computer software or tablet application, try restarting the software 
or application. If the problem remains, press and 

hold

 the ON button for 10 seconds and then release. Start the 

sensor in the usual way.

Turn Bluetooth off and then back on. Retry.

Mounting the Wireless Rotary Motion Sensor

The sensor case has two support rod holes that fit rods up to 12.7 mm 
in diameter, such as the ME-8736 45 cm Stainless Steel Rod, and the 
case can be put on the support rod using either of the support rod 
holes. 

It is possible to mount the Wireless Rotary Motion Sensor horizontally 
on a support rod with the Three-step Pulley facing up or facing 
sideways. You can mount the sensor vertically with the pulley facing 
forward. 

When mounted on a track as shown, a Rotary Motion Sensor could be 
used to measure the motion of a PASCO Cart as it is pulled by a string 
suspended over the Three-step Pulley of the sensor and attached to a 
hanging mass.
