Connecting the Strain Gauge and Force Motion sensor to the Mantis Cart
To Connect the Strain Gauge to the Force Motion sensor, you will need the Force Motion sensor, the extended wire connectors, a 3mm flat head micro screwdriver, the strain gauge and the Mantis cart.
Step 1 – Make sure you have the Force Motion sensor oriented with the Mantis logo facing up. Locate the screw connectors on the Force Motion sensor. These screw connectors will allow you to loosen the wire connector slots on top of the Force Motion sensor.

Step 2 – Using the 3mm flat head micro screwdriver, loosen the two farthest left screws.
HELPFUL HINTS:

  • Turning the screws counter clockwise will loosen them
  • Do not loosen the screws too much as they will fall out of the unit
  • The screws that you loosen are closest to the charging port on the Force Motion sensor
  • Have good lighting to see the screws

Step 3 – Locate the exposed wire end of the extended wire connector.

Step 4 – Locate the wire connector slots on top of the Force Motion sensor.

Step 5 – Place the red wire bare end into the first wire connector slot. Tighten the first screw connector.
HELPFUL HINTS:

  • Turning the screw clockwise will tighten it
  • Make sure you have the wire fully inserted into the wire connector slot
  • Do not over tighten the screw. Test the tightness by gently pulling the red wire and make sure the wire is securely connected. If the wire does not come out, it is tight enough. If the wire is able to be pulled out, loosen the connector screw and retry connecting the red wire.
  • Have good lighting to see the screws

Step 6 – Place the black wire bare end into the second wire connector slot. Tighten the second screw connector.
HELPFUL HINTS:

  • Turning the screw clockwise will tighten it
  • Make sure you have the wire fully inserted into the wire connector slot
  • Do not over tighten the screw. Test the tightness by gently pulling the blcak wire and make sure the wire is securely connected. If the wire does not come out, it is tight enough. If the wire is able to be pulled out, loosen the connector screw and retry connecting the black wire.
  • Have good lighting to see the screws

Step 7 – Locate the plastic connector end of the extended wire connector.

Step 8 – Locate the bare wire end of the strain gauge.

Step 9 – Firmly slide the bare wire ends of the strain gauge (lettering side up) into the plastic connector end (raised arrow up) of the extended wire connector.
HELPFUL HINTS:

  • Be careful not to bend or crimp the bare wire ends of the connector.
  • The lettering on the strain gauge wire connector needs to be facing up
  • The raised arrow on the extended wire connector needs to be facing up

Step 10 – Turn the Force Motion Sensor ON.
To turn the Force Motion Sensor ON, you will need the Force Motion Sensor that has been charged and ball point pen with the cap removed.
Step 10a – Locate the power button for the Force Motion Sensor.

Step 10b – Depress the power button for one full second using the tip end of a ball point pen.
The Force Motion Sensor will now display a red light inside the sensor, which lets you know the unit is ON and ready to be used. The red light will flash on every 5 seconds when the unit is ON. If the Force Motion Sensor does not power ON, the unit may need to be charged. If the Force Motion Sensor is charged, you may not have depressed the power button for the full one second.
Step 11 – Locate the strain gauge notch in the Mantis cart.
