4.7.7.3.7 Corner correction
In this menu item (under Calib), corner correction is performed for the digital
weighbridge load cell Pendeo
®
Truck.
Checking the corner load (dead load):
After assignment (see Chapter 4.7.7.3.3) and calibration (see Chapter 4.7.7.3.4), the
position of the load cells is clearly dened.
Mechanical corner correction:
A mechanical corner correction has to be carried out if the load is not evenly distributed
over the load cells, e.g. if the platform is wobbling.
The dead load on the load cells can be corrected using shims. If two coupled platforms are
connected, corner load checking or installation of shims for the platforms must be
performed independently.
Accessible via MENU - [Operating] - [System setup] - [Weighing points] - [Weighing
point x] - [Calib] - [View and assign load cells] .

The load cells are displayed with their item number, serial number, and load.
In this example, the load on a load cell does not need to be increased by a shim. A ne
calibration can be done by subsequent software corner correction.
Software corner correction:
If the corners are loaded in succession, the same value should be displayed on the device
at all times. An excessive deviation almost always means that the scale is tilted or
indicates load cell force shunts.
If the signal deviations cannot be resolved by carefully leveling the scale, the software
must be calibrated.
