Material: stainless steel. : 0.01 mm. Weight: approx. 268g Zero settings: Clean the surface of the measuring anvil heads with a soft cloth and then turn the gauge to bring two measuring surfaces in. If the two zero lines of the differential sleeve and the fixed barrel do not match, use the following two methods to adjust. Method I:If the error is less than 0.02mm (0.001), use the ratchet stop to tighten the screw, and then use the wrench to tighten the fixed barrel until two zero lines are aligned. Method II, if the error is greater than 0.02 mm (0.001), Step 1: Use the ratchet stop to tighten the screw, then loosen the ratchet stop with a wrench and remove the differential sleeve. Step 2: Re-align the zero lines of the fixed barrel and differential sleeve, and then put the ratchet stop back in. Adjust it again with Method I if necessary. Note: Under normal use, the micrometer does not need to be calibrated. Micrometers only need to be calibrated when they are severely worn. Package includes: 1 x internal micrometer. 1 x wrench. 1 x calibration ring. 1 x packaging box ProductSiteLaunchDate : 2024-09-07T15:37:05.474Z Size : One Size UnitCount : 1 UnspscCode : 41113700
