Like all Micrometers Depth Micrometers are precision measuring tools and should be treated with due care and attention. The scale of the Depth Micrometer differs from normal as the scale reads in reverse as the spindle extends to measure depths whereas external Micrometers the spindle retracts to measure. Remember always calibrate before use – How? – To a known standard.
