• Specification: Material: carbon steel Measuring range: 25 Resolution: zero Scope of application: 25 Specifications: Micrometer 0-25 Feature: Outer diameter micrometer the exterior dimensions measuring instruments, measure the distance between the two sides of the square body through use of helix principle Outer diameter micrometer is mainly used for measuring a variety of external dimensions Diameter micrometer dividing value is 0, the higher limit of dimension vary isn't greater than 300mm, divided right into a 25mm in keeping with specification Such as 0-25mm, 25-50mm and so on Diameter micrometer sort shown in the picture: (The photograph is for illustration only, does not point out the detailed structure) Instructions for use: 1 Clean the measuring floor earlier than use and proper the zero role 0-25mm direct alignment zero: 25mm above use the bar gauge aimed toward quasi-zero 2 Zero correction method: If the 0-bit line isn't always aligned with the baseline, first loose screw with a screwdriver slightly, with a wrench to adjust the baseline position, in order that the baseline alignment 0 taste bit line, then tighten the screws (See directions to be used photo 2) 3 When measuring, the micrometer must be perpendicular to the work piece under test, rotating drive measuring device, the measuring surface in contact with the paintings piece ought to be rotating gently, when the drive measuring gadget issued a slight "click, click on " sound, That is the particular size of the paintings piece under check four Locking gadget could be passive measurement of micro-screw again and forth Relax to the correct and lock to the left (See instructions to be used Figure 3) 5 When measuring, the left hand must hold the heat defend to stop body temperature transmitted to the micrometer, inflicting measurement error 6 One finish of the wrench can be adjusted zero, the opposite end can pull the drive measuring machine Warm tips: 1 Micrometer is a precision measuring tool, when used gently, after use in the uncovered elements covered with anti-rust oil, and placed in the box, put it on the dry and ventilated position 2 Measurement can not drive the micro-rotation cylinder, so as not to injury the accuracy Packages: 1 x Outside Micrometer (color random） 1 x Accessory
