Scale-calibration service helps users ensure quality operation
The Alliance Scale Calibration Service (photo) can be performed annually or at some other interval to ensure consistent accuracy and conformance to quality requirements. As a rule of thumb, if a scale is used for an hour or less per day, then an annual checkup is advised. If the scale is used for 1–2 h/d then calibration twice per year is recommended, while quarterly calibration is recommended for scales that are used for 3–4 h/d. Services include a visual and operation check of the operating mechanism, testing with NIST-traceable weights, and providing a calibration report and calibration certificate for an ISO audit. If necessary, a written report and estimated cost will be furnished for any scale requiring further maintenance, says the company. — Alliance Scale, Inc., Canton, Mass.
