Outside micrometerHigh precision, the micrometer range is 0-25mm, and the guaranteed scale is 0.01mm. Special keyEquipped with a professional key, which can easily adjust the zero position. It is convenient to adjust the data. High quality]Tapered bracket allows use in narrow grooves and narrow places. Likewise, the probe is made of hard and durable alloy. Satin chrome tube and lens barrel with contrasting black scale for easy reading. Shockproof PackageThe outer package of the micrometer adopts anti-shock blow molded shell to protect the micrometer accessories . Scope of applicationRecommended for mechanics, auto repair and mechanical workshops, tools or testing and all services, the author should work in different measurement ranges Instructions: 1. Wipe the measuring surface of the measuring anvil and the measuring surface of the micrometer screw with a soft cloth before use, rotate the force measuring device to bring the two measuring surfaces into contact, and observe whether the position " 0" is aligned. Fine adjustments can be made using a wrench. 2. When measuring, use the force measuring device to make the two measuring surfaces and the workpiece to be measured at the angle, until the rotating force measuring device makes a sound before reading. 3. Use the force measuring device correctly, do not use too much force, and do not directly rotate the scale sleeve for measurement. 4. The workpiece is measured in a static state, and the measurement axis should be consistent with the direction of the measured dimension during measurement, as shown in the following figure. 5. Reading method, the small reading of the micrometer is 0.01mm, please refer to the following details for how to read. Matters needing attention: Do not disassemble and assemble the micrometer arbitrarily. After use, wipe it clean and apply anti-rust oil to the box to keep the micrometer clean.
