Test Method for Calibrations

The load cell was calibrated comparatively against a calibrated load testing rig of the relevant capacity. It was installed into the test rig using the correct fitting rated to the relevant capacity of the unit under test.
All fittings were inspected by the engineer for alignment into the rig prior to any load being applied to the system.
Prior to the commencement of the test the unit under test was loaded to full capacity and held for 1 minute, then released to zero applied load and left to stabilise for 1 minute to exercise the mechanical portion of the load cell.
Each calibration point was taking in ascending order, the results of each reading are tabulated below.
All measurements are traceable to national standards.

A Calibrated digital multi meter was used to measure the output of the load cell
