The amount of weight loaded onto the test cart depends on the guidelines given in NIST Handbook 44 for a scale of that particular size & capacity. Utilizing a hydraulic lift system, the scale technician removes the test cart from the truck, before loading it with test weights. The heavy-duty test trucks contain heavy-duty test carts & thousands of pounds of certified test weights. The Michelli Weighing & Measurement heavy-duty test trucks are used for heavy capacity scale calibration, such as truck scale calibration & rail scale calibration. In that case, the scale technicians will adjust the scale until the reading produced when the test weights are placed upon the scale accurately depicts the known value of the test weights. If the weighment produced by the scale being calibrated does not equal the known value of the certified test weight, the scale is out of tolerance. (NIST Handbook 44 outlines specifications, tolerances & other technical requirements for weighing & measuring devices. Scale calibration is performed to standards outlined in the latest edition of NIST Handbook 44. The weight reading, or weighment, produced by the scale as a result should equal the known value of the test weight. © 2023 Cleveland Browns.During scale calibration, the Michelli Weighing & Measurement scale technicians use certified test weights, which have been assigned a known value, to test the scale.
