Calibrate a Smart Cart

Create a new two-point calibration for the Smart Cart's force sensor.

Before you start

Calibrating the Wireless Smart Cart's force sensor will require the following supplies:

• A 1 kilogram mass
• The Smart Cart hook attachment
• A horizontally mounted support rod to hold the Smart Cart
• String

The Smart Cart will need to be connected to a tablet or computer.

Calibration

1. Screw the hook attachment into the Smart Cart; this will connect the hook to the internal force sensor, allowing force measurements to be collected.

   

2. Tie a string to the attachment point on the opposite end of the Smart Cart from the hook; use this string to hang the cart from a horizontal rod.

3. Select Calibration from the Tools palette.
4. Make sure that Force is selected in the dropdown list. Click Next.

5. Make sure that Two Standards (2 point) is selected from the list of calibration options, then click Next.

   

6. Hang the 1 kilogram mass on the hook attachment.

7. The force on the sensor is now 9.8 N. Enter this known value into the Standard Value box, then click Set Current Value to Standard Value.
8. Remove the 1 kilogram mass from the hook attachment.

9. The force being exerted on the sensor is now 0 N. Enter this second known value into the new Standard Value box, then click Set Current Value to Standard Value.

   

10. Review your new calibration to ensure it is accurate, then click Finish.
