Internal Micrometer Measuring Tools 5-30 mm, Measuring Range 0.01 mm, with Wrench Calibration Ring and Packaging Box
Specifications: Type: Internal Micrometer Measuring range: 5 mm ~ 30 mm. Material: stainless steel. Precision: 0.01 mm. Weight: 268g (approx.) Zero settings: Clean the surface of the measuring anvil heads with a soft cloth. Then turn the gauge to contact two measuring surfaces. If two zero lines of the differential sleeve and fixed cylinder do not align, use the following two methods to adjust. Method I: If the error is less than 0.02 mm (0.001 inches), lock the screw with a pawl stop, and then pull the fixed cylinder up to two zero lines with the wrench. Method II, if the error is greater than 0.02 mm (0.001 inches), Step 1: Use the pawl stop to lock the screw firmly. Then loosen the pawl stop with a wrench and remove the differential sleeve. Step 2: Re-align zero lines of fixed sleeve and differential sleeve and reattach detent stop. If necessary, fit them again with Method I. Note: The micrometer does not need to be calibrated during normal use. The micrometer only needs to be calibrated if it is severely worn. Package includes: 1 x internal gauge. 1 x wrench. 1 x calibration ring. 1 x packaging box.
