5. Drive the vehicle off the weighbridge, one axle at a time. Take the weight measurements until you

have a value for each time an axle is removed from the weigh bridge

It is recommended that you copy or recreate the zero weights and span weights tables to complete

and calculate the weight values for each axle. See “Zero and span weights tables” on page 117.

See below for an example of this calculation.

It is recommended that the same weighbridge is used to take all weight measurements for both

the zero and span calibration processes.

Weighbridge Measurements

Weight Calculation

Axle Weight

G =

11500

Gross Weight = G

11500

a =

9500

Axle 1 = g - a

2000

b =

7500

Axle 2 = a - b

2000

c =

6000

Axle 3 = b - c

1500

d =

4500

Axle 4 = c - d

1500

e =

3000

Axle 5 = d - e

1500

f =

1500

Axle 6 = e - f

1500

The example above shows an how each axle weight can be derived by subtraction using a weighbridge.
