Thanks for sharing! We are always happy to hear this!

I like your thinking.

Glad you liked it.

I need this! It will truly help me to do my job more accurate.... Thanks Mitutoyo!

How i get job opportunity in mitutoyo

Can it wait for a bit? I'm in the middle of some calibrations

Most welcome!

Good question. You are correct that the calibration interval is really dependant on many factors and not standardized across the spectrum. For example, a blacksmith may never calibrated his/her trusty calipers. If they are off by a thou or two, no big deal and low risk. However, an automotive parts manufaturer might calibrate their shop calipers on a yearly basis. Some higher risk use, such as military branches, might calibrate every six months or even shorter! The calibration history of the product (have you noticed any drift in the readings), it's use, and associated risks will help guide your calibration interval decisions.

How my organization always does it is examine the track record of the equipment and see how much its readings change from calibration to calibration. If a piece of equipment doesn't drift from one calibration to another and is seemingly always in tolerance, then you are wasting your money if you calibrate it too often. Conversely, if it is usually out of tolerance when you calibrate it, you probably need to shorten your interval. Also, be aware that a piece of equipment just sitting on a shelf can still drift out of tolerance! For some equipment (particularly in the pressure measurement field), long term storage can be worse for accuracy than frequent use.

Glad it was helpful!

Of course, metrology is an area with a lot of job opportunities, and miss people who have experience in this field..

Yes. But you have to be open also to international practices. Some regulators are too rigid.

I would say that verification is just measuring and recording. Calibrating it would verify and make adjustments if needed

@@robertbach9376 Respectfully. Formally, "Calibration is the documented comparison of the measurement device to be calibrated against a traceable reference device." The above formal definition comes from the BIPM (Bureau International des Poids et Mesures). There is no Adjustment inferred in Calibration. In fact if you adjust an instrument or reference device, it requires re-calibration in order to issue a certificate. Calibration is always the final step of the process. The all important certification and documentation. An instrument should be able to pass through any certified calibration lab with all results matching within the degree of uncertainty. This is why we can produce complex things to tight tolerances in different parts of the world and have them assemble perfectly at the destination location. I do not wish to detract from an otherwise fine video, however I have seen a rise in the misuse of the term calibration that cannot be ignored. The consequence can prove to be very costly.

@@ernestopesto2874 yeah but they're French so their opinion doesn't count

@@robertbach9376 Back in the late 70's I studied a three year course in Engineering Inspection and Metrology at the Royal Melbourne Institute of Technology as part of my toolmaker apprenticeship training. We used to hold Mitutoyo measuring tools in high regard. Maybe I was mistaken.
