True or False: Adjustments to scales must meet maintenance tolerance values.

The assertion that adjustments to scales must meet maintenance tolerance values is true. Maintenance tolerance values are critical for ensuring that scales operate accurately and reliably. These values establish the acceptable limits for the performance of a scale and are vital for compliance with regulatory standards.

When a scale is adjusted, it is essential that such adjustments not only aim to correct any discrepancies but also ensure that the scale continues to fall within the specified tolerance limits. This ensures the precision of measurements in various applications, including trade, healthcare, and scientific measurements.

While one might consider adjustments to be optional based on particular contexts or types of scales, adhering to maintenance tolerance values is a standard practice necessary for upholding measurement integrity and accuracy. Therefore, the correct response as per the principle outlined in the question should affirm that adjustments to scales indeed need to meet these maintenance tolerance values.
