He is wrong. Calibration is the act of alignment into specifications. Verification is the act of testing the instrument to verify it meets published specifications. If the instrument fails verification then you perform a calibration to align it into specs. But what would I know? I only have been in Metrology for 34 yrs.
No, Calibration is as defined by ISO standards as 'The comparison of unit under test to a known standard traceable to NIST' Adjustment is the act of alignment into specifications, which is separate from calibration. Example, I have a cam-over torque wrench that is set at 15Nm. Using a torque transducer that is NIST traceable I test this wrench to determine if it is within the set tolerances. If it is outside those tolerances, I adjust the wrench and recalibrate. If it then passes I verify that the wrench is working as intended, and will work for the application that it is to be used for.
You are doing wonderful job all ways
Thanks Prabhu
❤️
Thanks Alok
Thanks for making this video as asked by me . It cleared my doubt.
Sir can you please make a video on
Different phases of APQP ? In breaf
Thanks for the feedback
Please see video from 13 Sep 2020 to 18 Nov 2020 for 8 videos related to APQP process.
Ok sir

Dear Anthony, Thanks for your response and feedback. Please suggest what needs to be corrected in the video so that I can understand and improve.
