Economy Quality Micrometer Screw Gauge 0-25 mm [0.01mm Accuracy] Micrometer 0-25mm/0.001mm Outside Micrometer Screw Gauge + Storage Box Precision Measuring Instrument Tool to Measure Distance Between Two Sides, Outer Diameter & Depth, External Dimensions Micro Meter Vernier Caliper Ruler 1. Great for machinists and jewelers for precise measurements. 2. This gauge ranges from 0.01-25mm. 3. Measuring faces are manufactured from stainless steel for maximum durability. 4. Packaged with plastic hard case for portable carrying. Smooth surface with chrome clear scale Resolution: 0.01mm Micrometer Type: Outside Micrometers Display Type: Analogue Measuring Range: 0.01 - 25mm Dividing Value / Accuracy / Graduation: 0.01mm Case Size: 11*4*1cm Package includes 1 x Outside Micrometer 1 x Plastic Storage Box Instructions for use: 1. Clean the measuring surface before use and correct the zero position. 0-25mm direct alignment zero: 25mm above use the bar gauge aimed at quasi-zero. 2. Zero correction method: If the 0-bit line is not aligned with the baseline, first loose screw with a screwdriver slightly, with a wrench to adjust the baseline position, so that the baseline alignment 0 taste bit line, then tighten the screws. (See instructions for use picture 2) 3. When measuring, the micrometer should be perpendicular 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 passive measurement of micro-screw back and forth. Relax to the right and lock to the left. (See instructions for use Figure 3) 5. When measuring, the left hand should hold the heat shield to prevent body temperature transmitted to the micrometer, causing measurement error. 6. One end of the wrench can be adjusted zero; the other end can pull the force measuring device. Note: 1. Micrometer is a precision measuring tool, please use it gently. 2. After using in the exposed room please coated with anti-rust oil, and put into the box, placed in a dry and ventilated place. 3. Do not force to turn the differential tube, so as not to damage the accuracy. 4. Do not attempt to remove the micrometer parts or it will be damaged and cannot be used. 5. The length of the micrometer test cycle should be determined according to the specific circumstances of use.
