									Rigid Truck Scale Calibration




Before calibration can be done the vehicle axle weights must be determined.
Pull the vehicle onto the weighbridge and take the GVW reading, then pull the front
axle just off the weighbridge and record the rear bogie weight. Subtract the drive bogie
weight from the GVW weight to give your steer axle weight. This must be done with an
empty vehicle then with as full load as possible for the heavy calibration. You can
calibrate heavy or empty in any order. Calibrating Empty Weights – Vehicle must
be empty and empty axle weights recorded as above. Ensure lift axle is down if
applicable and steering axle is straight.
Park on a flat level surface and release brakes, ensure vehicle does not roll. For safety
chock vehicle wheels if necessary.

       GVW, and net weight scroll down or up using the up ▲or down▼ keys.


CHECKWEIGHING? Remember, to check weigh ALWAYS weigh your vehicle on a
flat level surface, inclines may affect the accuracy of the system and alarm targets. If
the vehicle is loaded from the rear on small loads GVW will not be accurate, observe
the drive axle weight to determine load as front axle may have a negative input until
load is forward of the rear axles.
Ensure steering wheels are straight; briefly release brakes to ensure suspension is
free or fully inflated.
When you want to weigh, you will need to weigh the vehicle the same way every time.
To ensure calibration accuracy it is recommended that the same weighbridge is used
for empty and full weights.
This system is for guide use only.
