You have just purchased new measurement & test equipment and are ready to calibrate it. You are off to a good start! Don't let this happen to you.
3 Things You Should Never Do With New Measurement & Test Equipment!
Reuse an existing ID number
You replaced a 6 inch caliper with a new 6 inch caliper. Same brand. Same model number. So why not use the same ID number? This is a common mistake that is often made with new measurement & test equipment. Why is is this a mistake?
Unique ID numbers need to remain assigned to a specific gage so that traceability can be preserved. In an audit, you need to be able to trace measurements to a specific gage. If you reuse ID numbers you lose that gage specific traceability. Think of them as the fingerprint of the gage.
Assume the calibration cycle is the same
Why wouldn't the cycle be the same? There is a gap in many Quality Management Systems in regards to calibration. No stated policy on how calibration cycles are determined and often no statistical basis on how to determine calibration cycles. If you assume this is the role of your calibration company, you are mistaken. ISO 17015 does not allow accredited calibration companies to provide recommendations on calibration cycle time.
You need to gather historical data and make informed decisions as to all calibration cycle times. This approach is fundamental to successful risk management. Allow the data to inform you when a gage becomes "stable" and do not assume that every gage behaves the same. look at individual data and collective group data e.g. Calipers, Micrometers, Multimeters, etc. and use statistical analysis to guide your risk management decisions in regards to calibration cycle frequency.
Open the box and use it
Read the instructions! Most new measurement & test equipment will have specific methods for acclimation to environment and cleaning instructions. Gage Blocks are often shipped with a protective coating that must be properly removed before use. Do not assume that denatured alcohol is the best method for cleaning new gages before use. Read the instructions. You may permanently damage the device using improper solvents for cleaning. Digital measurement & test equipment often have very specific battery requirements. The wrong battery can have an adverse effect on measurement results.
