How should we know when we need calibrate !!

Check out these 5 important signs that indicate your scale 'needs calibration.'

Many organizations wait for the scheduled calibration date according to the calendar.
But in reality, scales may start to drift before the scheduled time without the user realizing it!

Here are 5 important signs that your scale should be calibrated

1️⃣ Inconsistent measured values
Weighing the same object but getting different numbers each time.
This is the first sign of deviation that should not be ignored.

2️⃣ Weighing results are inconsistent with other machines
When compared to another scale or results from other processes and significant discrepancies are found, the QA team should immediately check the accuracy.

3️⃣ The scale has been moved or its environment has changed
Moving the scale, changing its operating area, including environmental factors such as vibrations, temperature, or uneven surfaces, all affect the accuracy of the scale. Therefore, before relocating the scale, the placement area should be prepared appropriately to prevent potential measurement deviations.

4️⃣ Scales subjected to heavy or continuous use
Scales that are frequently used, especially on production lines, are more prone to wear and tear. Even if they are still functioning normally, their accuracy may decrease. Therefore, it is crucial to regularly calibrate weighing and measuring instruments to ensure smooth and highly efficient production.

5️⃣ Approaching an audit or customer inspection
If scales are used in the quality control process, pre-calibration helps reduce the risk of questions regarding the reliability of weighing results. Therefore, to ensure a smooth audit (calibration) process, it is recommended to contact a specialized lab for advice on calibrating measuring and weighing instruments and for preparing the necessary documents at least 3 months in advance.

From the 5 key signals above, if upon inspection they are found to fall under TMC's recommendation, it is advised to promptly calibrate, because even though the scale is still functioning, it does not mean that the weighing results are always accurate.

Regularly observing these 5 key signals and planning proper calibration for the scales or measuring instruments used is one of the most effective and sustainable quality control methods.
