Hi Jenna,
Calibration tolerances should be determined from a combination of factors. These factors includes:
• Requirements of the process
- what would be the biggest measurement correction that will not affect the quality of your products.
• Capability of available test equipment
- is your measuring instrument capable to inform you the value of your set tolerance? ( ex. your temperature tolerance is +/- 1.2 deg C; your temperature indicator must be capable of displaying at least 0.01 deg C for strict compliance.)
• Consistency with similar instruments at your facility
- this is useful specially to those manufacturing company's with multiple independent similar lines which produces same products.
• Manufacturer’s specified tolerance
- this is the most important yet most neglected information by the end users. you can use the manufacturer's specification but reconsider the depreciation of performance. Brand new instrument performance is not the same with instrument who served for 3 or more years.
