How To Calibrate A Balance with Weights – Professional Solutions From ACCURATEWT

Regular calibration is the cornerstone of precision in any laboratory or industrial setting. It ensures your analytical and electronic balances deliver the accuracy, reliability, and consistency required for critical operations. At ACCURATEWT, we specialize in providing comprehensive calibration solutions that make the entire process smarter, safer, and more efficient.

Follow this professional guide to ensure your balance calibration is performed to the highest standard.

Step 1: Preparation is Key

A proper calibration begins with a controlled environment. Ensure your balance is placed on a stable, level surface, free from vibrations and air currents. Always use the draft shield to minimize environmental interference, which is crucial for achieving stable and repeatable readings.

Step 2: Select the Correct Calibration Weights

The accuracy of your calibration is directly dependent on the quality of your standard weights. Selecting the right class of weights is paramount, and it all starts with your balance's readability.

Matching Weight Class to Your Balance's Precision

The following table provides a clear guideline for selecting the appropriate weights class based on your balance's readability:

ACCURATEWT offers a complete range of OIML R111 standard weights, with capacities from 1 mg to 10 tons and classes from E1 to M2, designed to meet both precision laboratory and industrial demands. Our weights are crafted from premium materials—including non-magnetic stainless steel, cast iron, and pure steel—ensuring durability, traceability, and compliance for diverse applications.

Step 3: Handle Weights with Precision and Ease

Proper handling is critical to maintain the integrity of your weights and your safety.

 For Precision Balances: Always use anti-static tweezers to handle small weights, preventing contamination and preserving their accuracy.

 For High-Capacity Scales: For weights of 10 kg and above, utilize our Intelligence Aided Lifting Equipment and Weight Handles. This ergonomic equipment reduces physical strain on operators and enables precise, safe positioning, transforming heavy-duty calibration from a chore into a seamless operation.

Step 4: Execute the Calibration Procedure

Initiate the balance's internal calibration mode according to the manufacturer's instructions. Gently place the selected standard weights at the center of the pan. The system will compare the measured value against the reference standard. For the most accurate results across the entire weighing range, we recommend performing a multi-point calibration using weights of different values.

Step 5: Partner for Complete Calibration Ecosystems
