说明

• Features: High high quality alloy measuring heads can be utilized for various inside size measurement, fantastic workmanship and no burr laser marking line for convenient studying main micrometer body is made of chrome steel with chrome plated surface, wear-resisting and sturdy with locking device, precise machinery structure make it more intuitive and convenient to read ratchet stop system guarantees accurate repetitive readings Specifications: Type: Inside micrometer Measuring Range: 5mm~30mm Material: Stainless stee Zeroing:Clean the surface of measuring anvil heads with a comfortable cloth, then rotate measuring machine to make two measuring surface touch If two zero strains of differential sleeve and stuck barrel don't alignment, use the ensuing two tips on how to modify I, if the error is less than 0 (0"), use ratchet give up to lock screw tightly, then use wrench to pull constant barrel until two zero traces alignment II, if the mistake is greater than 0 (0 "),Step1, use ratchet stop to lock screw tightly, then use wrench to loosen the ratchet quit and take away differential sleeve, re-align 0 traces of constant barrel and differential sleeve, then put ratchet quit back on If necessary, modify it back using system I: There is no should calibrate micrometer during typical use Micrometer solely want calibration when it's seriously worn Package Includes: 1 xDigital Inside Micrometer 1 x Wrench 1 x Packing Box note:5-30mm digital micrometer is equipped with a 5mm ring gauge25-50mm electronic micrometer is supplied with a 25mm ring gauge50-75mm electronic micrometer with out ring gauge75-100mm electronic micrometer with out ring gauge
