5-30 mm Range Internal Micrometer, Stainless Steel 0.01 mm Precision Hole Bore Inner Diameter Pressure Gauge Industrial Measuring Tools
5-30 mm Range Internal Micrometer, Stainless Steel 0.01 mm Precision Hole Bore Inner Diameter Pressure Gauge Industrial Measuring Tools
Technical data: Type: Internal Micrometer Measuring range: 5 mm ~ 30 mm. Material: stainless steel. Precision: 0.01 mm. Weight: approx. 268 g. Zeros: Clean the surface of the measuring anvil heads with a soft cloth. Then turn the gauge to make two measuring surface contacts. If 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. Use less than 0.02 mm (0.001 inches) to hold the screw with the ratchet stop. Pull on the fixed barrel with a wrench until two zero lines are aligned. Method II, if the error is greater than 0.02 mm (0.001 inches), Step 1: Use the ratchet stop to hold the screw firmly, and 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 put the ratchet stop back on. If necessary, adjust it again with Method I. Note: During normal use, the micrometer does not need to be calibrated. Micrometers only need to be calibrated under heavy wear and tear. Package includes: 1 x internal micrometer. 1 x wrench. 1 x calibration ring. 1 x packaging box.
