Test Weights & Crane Weights FAQs
Yes, test weights can be used to calibrate both digital and mechanical (non-digital) weighing systems, ensuring they remain accurate and reliable. For mechanical systems, the weights are typically used to check spring balances or load cells.
Certified test weights are calibrated and verified to meet specific national or international standards, making them suitable for high-accuracy applications. Non-certified weights are typically used for less stringent calibration needs. For industries that require compliance with regulations, certified test weights are recommended.
When using test weights outdoors, ensure they are protected from exposure to weather, dirt, or extreme temperature changes, as these conditions can affect their precision. Using weights that are specifically designed for outdoor use, such as those made from corrosion-resistant materials, is recommended.
To maintain the accuracy of test weights, store them in a controlled environment away from extreme temperatures, moisture, or physical damage. Regularly calibrating and using certified weights ensures they remain within tolerances and provide reliable results.
If a test weight is dropped or damaged, it may no longer provide accurate calibration. Inspect it for any visible signs of damage or wear, and if necessary, return it for recalibration or replacement to maintain the integrity of your measurements.
