About Outside Micrometer Vernier Scale Thickness

Features: Material: Alloy steel Measuring Range: 25-50mm, 50-75mm Accuracy: 0.01mm Instructions: 1. Clean the measuring surface and correct the zero position before use. 0-25mm direct alignment to zero: 25mm or more with the school team for the quasi-zero position. 2. Method of correcting the zero position: If the 0-bit line is not aligned with the reference line, first loosen the screw with a screwdriver, adjust the position of the reference line with a wrench, align the reference line with the 0-bit line, and then tighten with a screwdriver. Tightening the screw. (See instructions for use Figure 2) 3. When measuring, the micrometer should be perpendicular to the workpiece to be tested. Rotate the force measuring device. When the measuring surface touches the workpiece to be tested, gently rotate the force measuring device. When the measuring device emits a slight “shoo” sound, This is the actual size of the workpiece being tested. 4. The locking device can passively measure the forward and backward movement of the micro screw. Relax to the right and lock to the left. (See instructions for use in Figure 3) 5. When measuring, the left hand should hold the heat shield to prevent the body temperature from being transmitted to the micrometer, causing measurement errors. 6. One end of the wrench can be adjusted to zero position, and the other end can tighten the force measuring device. Package Content: 1 x Micrometer 1 x Wrench 1 x Box
