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
-
Screw the hook attachment into the Smart Cart; this will connect the hook to the internal force sensor, allowing force measurements to be collected.
-
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.
- Select Calibration from the Tools palette.
- Make sure that Force is selected in the dropdown list. Click Next.
-
Make sure that Two Standards (2 point) is selected from the list of calibration options, then click Next.
-
Hang the 1 kilogram mass on the hook attachment.
- 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.
- Remove the 1 kilogram mass from the hook attachment.
-
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.
-
Review your new calibration to ensure it is accurate, then click Finish.
