Scale Calibration

Scale Calibration Guide

Scale calibration is important if your business relies on a weighing scale.

Weighing scales over time get worn out and accuracy degrades. They can be sensitive to mechanical and electrical shock.

Weighing scales can corrode if there’s a lot of moisture or oil within the working environment they are used.

What is Scale Calibration?

Scale calibration is measuring the level of accuracy. It’s important when you’re testing your scales for their accuracy. If your scales aren’t accurate, they can harm your business, or even result in product quality issues, scrapped batches, or even a product recall.

Calibration of a scale is a procedure in which a scale technician uses a certified test weight traceable to the United Kingdom National Standards.

The display indicator must show a zero reading when there is no weight on the scale. When a known test weight is on the scale, the indicator must display the exact amount of applied weight within a specific tolerance.

How often should you calibrate your scales?

The frequency of calibration depends on a few different factors. Manufacturers typically recommend calibrating your scales at least once per month, but if that’s not possible, check for accuracy at least every twelve months.

The environment where your scales operate plays an important role. For example, if your weighing machine is in an area that contains fluids, dust, or other substances, it could have a buildup of these substances that effect the reliability and operation of the scale.

Accurate weight is important to your business. It’s most likely that more frequent calibrations will be necessary if your company can’t afford to have any inaccuracy.

Once you’ve determined how often your scales need calibrating, you’ll want to sign up for a service contract with a local scale company.

It involves a general inspection and servicing of your equipment to ensure it maintains accuracy.

If your weighing machine is inaccurate, you’ll want to have it calibrated. It’s basically a series of tests to help maintain the accuracy you need for your weighing requirements.

There are a lot of potential problems with weighing scales. Environmental conditions can affect them, which can lead to false readings.
