Digital Caliper Calibration 

There are only videos of checking, but nothing to calibrate or adjust the caliper back to tolerances

Hello sir,u r taking reading at middle jaw but customer normally check at end of jaw so exact error will be at end of jaw

Internal jaw parallism

Hello. What calibration procedure did you use? why you did not use OPtical parallel for flatness? Thanks

What standard u r using for performing this calibration not 3651

Sir how much tolerance is acceptable of length, parallelism, zero setting and depth zero?

Can you share the observation sheet format
