Abstract
A scale calibration device and method of use. The device may include a base supportable on and movable along a surface to a location. The base further includes a base surface for supporting a scale to be calibrated proximate the location. The device includes a frame assembly connected to the base and operable to support, in a position over the base surface, means for simulating a dead weight, the means being operable to apply a force to the scale supported on the base surface.
Claims15
A device comprising:
- a base including a base surface, the base configured to move the device along a surface and to support a scale to be calibrated;
- a handle detachably connected to the base and configured to be grasped by a user to move the device;
- a frame assembly connected to the base, the frame assembly including a first upright beam and a second upright beam spaced apart by a gap from the first upright beam, the first and second upright beams being connected to and extending away from the base, the frame assembly further including a crossbeam connected to and extending between the first and second upright beams to interconnect the first and second upright beams, the crossbeam spaced apart from the base surface;
- a frame connection mechanism configured to releasably connect the frame assembly to the base;
- a force applying assembly supported by the frame assembly and extending transverse from the crossbeam, the force applying assembly being configured to apply a force simulating a dead weight to the scale supported on the base surface;
- and
- a support assembly connected to one selected from the group consisting of the base, the handle, and the frame assembly, the support assembly configured to support a computing device for use in calibration of the scale.

A method of calibrating a scale, the method comprising:
- providing a scale calibration device including a base with a base surface, the base configured move the calibration device along a surface and to support a scale to be calibrated, a handle detachably connected to the base and configured to be grasped by a user to move the scale calibration device, a frame assembly connectable to the base and including a first upright beam and a second upright beam connected to and extending away from the base, and a crossbeam connected to and extending between the first and second upright beams to interconnect the first and second upright beams, a frame connection mechanism, a force applying assembly supported by the frame assembly and extending transverse from the crossbeam, and a support assembly connected to one selected from the group consisting of the base, the handle, and the frame assembly, the support assembly configured to support a computing device for use in calibration of the scale;
- moving the calibration device to a location;
- proximate the location, utilizing the frame connection mechanism to releasably connect the frame assembly to the base;
- proximate the location, supporting a scale to be calibrated on the base surface;
- and
- with the force applying assembly, applying a force simulating a dead weight to the scale supported on the base surface to calibrate the scale.
