4.3 Center of Gravity
The instrument is able to calculate and print the center of gravity coordinates of the vehicle being weighed.
NOTE: The weight of each wheel weigh pad must be greater than zero to calculate center of gravity.
The Gravity Center cell only displays on the Ai-1 indicator display when three or more wheel weigh pads are connected.
Follow this procedure to calculate the center of gravity of a vehicle with four wheels.
1. Position vehicle on the wheel weigh pads.
2. Press the gravity center cell on the primary weigh screen of the Ai-1 indicator.
3. Input the vehicle measurements. Refer to
Figure 4-2
for how to specify the coordinates.
Example: vehicle with four wheels, that has a width of 13 ft and a length of 15 ft.
