To maximize a scale’s life, performance, and accuracy while minimizing downtime, preventative maintenance is crucial. The volume of the product being weighed should be taken into account when developing a preventative maintenance schedule, but as a general rule, at least two maintenance sessions should be performed annually. Before problems arise, we inspect the scales to find any potential problem spots. Check the scale’s accuracy by using it. Correct any tolerance problems by calibrating the scale. Show thorough test results and certifications. The National Institute of Standards and Technology’s testing and calibration regulations are rigorously adhered to by Armour Scale Company (NIST Handbook-44).
