Several factors can cause a calibration weight to go out of tolerance:
- Environmental Conditions: Changes in temperature, humidity, and air pressure can affect the material properties of the weight, leading to variations in its mass.
- Physical Damage: Dropping or mishandling the weight can cause deformation or damage to its surface, altering its mass distribution and calibration.
- Corrosion or Contamination: Exposure to corrosive substances or contaminants can affect the weight’s material composition, leading to changes in mass over time.
- Wear and Tear: Continuous use of the weight without proper maintenance or cleaning can result in gradual wear and tear, affecting its accuracy.
- Storage Conditions: Improper storage, such as exposure to extreme temperatures, moisture, or chemicals, can degrade the quality of the weight and impact its calibration.
- Manufacturing Defects: In some cases, calibration weights may have inherent manufacturing defects that become apparent over time, causing them to drift out of tolerance.
- Calibration Equipment Issues: Errors in the calibration equipment or procedure can also contribute to inaccuracies in weight calibration.
To maintain the accuracy of your calibration weight, it’s essential to store it properly, handle it with care, regularly inspect it for damage or signs of wear, and calibrate it using reliable
