Weighing scale calibration: why it matters and how to prepare

What is scale calibration?

Calibration compares a scale's indication with suitable reference weights at agreed points and reports results and associated uncertainty. Adjustment and repair are separate activities.

Why does it matter to business?

Manufacturers use weighing for incoming materials, recipes and product checks. Laboratories, food production and logistics also rely on suitable weighing results. Calibration supports decisions about fitness for use.

Legal verification for trade is separate from calibration; check the rules applicable to your scale and business.

Choose points and prepare your equipment

Provide the make, model, capacity, resolution, working loads, location and acceptance criteria. Points should reflect actual use and the agreed method. Confirm the instrument, range and applicable accredited scope with SK before ordering.

• Set the scale level and protect it from vibration and drafts
• Check zero, tare correctly and wait for a stable indication
• Avoid overloading and perform suitable interim checks
