Using This low cost Digital Calliper = PASS / FAIL = How to TEST accuracy and how to use. By comparison a digital calliper is surely the most useful measuring tool in a shop, from machinist, to mechanics, to hobbyist, etc... We all need to make precise measurements. Even not being the most precise tool in metrology, the calliper is the most precise tool many people will ever use. How can we know if this tool meets our standards, by testing it according to a reliable standard, the ASME B89.1.14 is the basis on testing a common caliper. We'll test the 4 basic functions and see if this tool is good enough to be in anyone's toolbox... We'll just get 2 birds with one stone, this caliper was given to me by Banggood for purpose of evaluation, so, by needing to make the procedure to see if it would be a PASS or a FAIL, might as well make a detalied video on how it's done, if you need to do the same for something you own or thinking to acquire, then, you can inspire yourself from this video in order to test your own tools... ==================================================== """DISCLAIMER""" This tool was given to me by Banggood in order to make an evaluation, this is my evaluation in real time. ==================================================== Here is the direct link to the calliper tested in this video.
