Clear marking line for convenient reading. The main micrometer body is made of stainless steel with chrome plated surface, wear-resisting and . Designed with locking device, precise machinery structure make it more intuitive and convenient to read. Built-in ratchet stop device ensures accurate repetitive readings. Specifications: Type: Inside micrometer Measuring Range: 5mm~30mm Material: Stainless steel : 0.01mm Weight: 268g(approx.) : Clean the of measuring anvil heads with a soft cloth, then rotate measuring device to make two measuring . If two zero lines of differential sleeve and fixed do not alignment, use the following two methods to adjust. Method I, if the error is less than 0.02mm (0.001), use ratchet stop to lock screw tightly, then use wrench to pull fixed till two zero lines alignment. Method II, if the error is greater than 0.02mm (0.001 ), Step1, use ratchet stop to lock screw tightly, then use wrench to loosen the ratchet stop and remove differential sleeve. Step2, re-align zero lines of fixed and differential sleeve, then put ratchet stop back on. If necessary, adjust it again using method I. Note: There is no need to calibrate micrometer during common use. Micrometer only need calibration when it
