Thước Cặp Cơ Khí 0-25mm

Specification: Material: carbon steel Measuring range: 25 Resolution: 0.001 Scope of application: 25 Specifications: Micrometer 0-25 Feature: Outer diameter micrometer the externaldimensions measuring instruments, measure the distance between the two sides ofthe square frame by use of helix principle. Outer diameter micrometer is mainlyused for measuring a variety of external dimensions. Diameter micrometer dividing value is0.01mm, the upper limit of measurement range is not more than 300mm, dividedinto a 25mm per specification. Such as 0-25mm, 25-50mm ...... and so on. Diameter micrometer form shown in thepicture: (The picture is for illustration only, does not indicate the detailedstructure.) Instructions for use: 1. Clean the measuring surface before useand correct the zero position. 0-25mm direct alignment zero: 25mm above use thebar gauge aimed at quasi-zero. 2. Zero correction method: If the 0-bitline is not aligned with the baseline, first loose screw with a screwdriverslightly, with a wrench to adjust the baseline position, so that the baselinealignment 0 taste bit line, then tighten the screws. (See instructions for usepicture 2) 3. When measuring, the micrometer should beperpendicular to the work piece under test, rotating force measuring device,the measuring surface in contact with the work piece should be rotating gently,when the force measuring device issued a slight "click, click ..."sound, That is the actual size of the work piece under test. 4. Locking device can be passivemeasurement of micro-screw back and forth. Relax to the right and lock to theleft. (See instructions for use Figure 3) 5. When measuring, the left hand shouldhold the heat shield to prevent body temperature transmitted to the micrometer,causing measurement error. 6. One end of the wrench can be adjustedzero, the other end can pull the force measuring device. Warm tips: 1. Micrometer is a precision measuringtool, when used gently, after use in the exposed parts coated with anti-rustoil, and placed in the box, put it at the dry and ventilated place. 2. Measurement cannot force themicro-rotation cylinder, so as not to damage the accuracy. Included: 1 x Outside Micrometer 1 x Accessory
