Inner Diameter Micrometer Centimetre Card Measuring Tool Spiral Micrometer Measuring Tool 5-30mm
Inner Diameter Micrometer Centimetre Card Measuring Tool Spiral Micrometer Measuring Tool 5-30mm
Specifications: Type: internal micrometer Measuring range: 5 mm ~ 30 mm Material: stainless steel Precision: 0.01 mm Weight: approx. 268 g Zero settings: Clean the surface of the measuring anvil heads with a soft cloth, then turn the gauge to touch two measuring surfaces. If two zero lines of differential sleeve and fixed barrel do not escape, use the following two methods to adjust. Method I, if the error is less than 0.02 mm (0.001 inches), use the ratchet stop to lock the screw tightly, then use a spanner to pull the fixed run until two zero lines are aligned. Method II if the error is greater than 0.02 mm (0.001 inch), Step 1:Use the ratchet stop to tighten the screw, then use the wrench to loosen the ratchet stop and remove the differential sleeve. Step 2, realign the zero lines of the fixed barrel and the differential sleeve, then replace the ratchet stop again. Adjust it again if necessary with method I. Note: the micrometer does not need to be calibrated during general use. The micrometer only needs to be calibrated if it is heavily worn out. Package includes: 1 x internal micrometer. 1 x wrench. 1 x calibration ring. 1 x packaging box.
