Internal Micrometer, 5-30mm 0.01mm Inner Dimension Micrometer Inner Diameter Hole Diameter Precision Gauge
Technical data: Type: Internal Micrometer Measuring range: 5 mm ~ 30 mm. Material: stainless steel. Accuracy: 0.01 mm. Weight: approx. 268g Zero position: Clean the surface of the anvil detectors with a soft cloth and then rotate the gauge to make two surface measurements. If two neutral axes of the differential sleeve and a fixed barrel do not align, use the following two methods to adjust. A method that, if the error is less than 0.001 inches, use a ratchet stop to lock the screw tightly, then use the wrench to pull the fixed barrel to two zero lines. Method II, if the error is greater than 0.02 mm (0.001 inches), Step1, use the ratchet stop to lock the screw tightly, then use keys to loosen the ratchet and remove the differential sleeve. Step2, align zero fixed rod and differential sleeve, then stop the ratchet again. Adjust again with Method I if necessary. Note: It is not necessary to calibrate micrometers during the usual use of micrometers only calibration when it is heavily consumed. Package includes: 1 x Inner Knife 1 x Wrench 1 x Calibration Ring 1 x Packing Box
