Inaccurate Scales Could Mean Thousands of Dollars Lost Each Year

When material is purchased or sold based on weight, it is imperative that the scale being used to measure that weight produces accurate results. A scale that is producing inaccurate readings could lead to thousands of dollars in losses. Let’s illustrate the potential losses associated with inaccurate scales in the example below.

Imagine a truck scale is used at the entrance to a landfill to charge $40.80 per ton (or $0.02 per lb.) for materials entering the facility. Upon inspection, the scale is 200 lbs. out of tolerance and has been weighing light. For every 200 lbs. not being weighed, the landfill is losing four dollars. If there are 100 trucks weighing in on this scale every day, five days per week, the inaccuracy could cost the landfill $104,000 each year.

How can businesses ensure accuracy?

Preventative maintenance and regular inspections are the keys to ensuring accuracy. While many people understand the importance of proper maintenance, it’s easy for these tasks to get overlooked. By instituting a preventative maintenance plan, facilities can minimize the risk of inaccurate scales and keep equipment in great working order. In addition, regular inspections by a certified calibration technician with certified test weights are the best way to ensure scales remain in tolerance.

Preventative Maintenance Tips to Help Ensure Accuracy


1. Regularly clean the scale to remove dirt and debris from the scale deck, entrance/exit ramps, and underneath the scale to ensure proper functionality.


2. Establish a preventative maintenance schedule and stick to it. By prioritizing preventative maintenance, operators can minimize the risk of both an inaccurate scale and unplanned downtime for repairs.


3. Utilize a quality service provider to perform regular scale inspections. After the inspection, ask the service technician if there are any additional steps operators can take between maintenance visits to help ensure accuracy.

  • The service provider should utilize a standard, repeatable inspection method based on Handbook 44.
  • The service technicians should be state certified.
  • The test weights used during the inspection should be certified.

How Michelli Weighing & Measurement Can Help with Preventative Maintenance

The Michelli Weighing & Measurement team provides preventative maintenance service agreements to help keep scales within tolerance and operations running smoothly. These service agreements allow Michelli customers to establish a preventative maintenance schedule (including preferred days and times for service), lock in service rates, and obtain discounts on replacement parts if needed. Preventative maintenance service agreements help Michelli customers keep up with maintenance-related activities and minimize the risk of inaccurate scales.

Track Assets for Planning Purposes

Another benefit to instituting a preventative maintenance plan is that it allows facility managers to keep up with the status of their assets. Going one step further, utilizing an asset management system could allow managers to schedule downtime for service, identify patterns with faulty equipment, and forecast future equipment purchases.

TRAC allows users to quickly access historical calibration records, set calibration schedules & receive reminders as due dates approach to help you maintain traceability.

Asset management also allows users to monitor their maintenance schedules & increase or decrease scale service as needed. For example, if bi-monthly scale inspections have not uncovered any glaring inaccuracies, perhaps the operator could reduce inspection frequency.

Also, asset tracking allows facility managers to identify patterns with problematic equipment. For example, it’s easy to see if certain scales are repeatedly found out of tolerance during inspections. This allows managers to plan for equipment replacement and budget accordingly.
