Scale Calibration Tips and Best Practices

August 10, 2020

Scale calibration is an important aspect of delivering reliable, accurate goods and services. Of course, proper calibration depends on the use of calibration best practices. To keep your scales standardized, use the following tips from your local weight scale calibration company in South Texas.


How often you should calibrate your scale depends on three major factors. The first is regulations. Does the law require you to calibrate your scale annually? Quarterly? Daily? Always follow the laws that govern your industry when deciding how often to calibrate your scale.
The second factor is the commodity itself. The accuracy of the weight is more important for some commodities than others. If you are weighing a product that is critical in a successful mix/ batch or compound, its weight is typically more critical. Another is commodity price, as in a truck load of sand costs far less than a truck load of copper. In these scenarios it is advised you should calibrate more often as the cost of a calibration will typically be far Lee’s than the potential loss of revenue from inventory loss, production rework and loss off your company’s reputation.
The third thing to consider to determine your calibration frequency is environmental and process conditions. If a scale experiences a lot of agitation, for example, this movement can affect the scale’s calibration. If conditions are likely to drive your scale out of bounds, then you should calibrate it more frequently.
Typical frequencies for calibration vary from annual to monthly, with spot checks between each calibration.


Always use an established weight scale calibration company in South Texas for your scale calibration. This service will use certified test weights that meet accepted standards to calibrate your scale. Verify with the company that all their weights are certified and are retested each year.


When you test a scale, it is crucial to properly document each test. As you work with a weight scale calibration company in South Texas, make sure they provide key information and findings for each test. These include the provider’s Weights and Measurements license number, a copy of the certified test weight documentation, equipment specifications, test readings, acceptance tolerances used, overall calibration readings and whether the scale failed or passed the test.


It’s best to partner with a weight scale calibration company in South Texas before state inspections. This will ensure your scales are properly calibrated to help you avoid inspection failure. If an inspector finds that your scale is out of bounds, you may have to shut it down until it can be recalibrated. To avoid this scenario, have your scale properly calibrated before each inspection.


Make sure the company you work with for your calibration services is a reputable source. They should conduct inspections based on regulations in the NIST Handbook. Calculations and processes should adhere to these standards, as well as reporting methods. Look for an experienced company with a good reputation in the industry.
