1. The surface should be clean before using measurement, zero and calibration. For 0-25mm(0.00-0.98in), directly align with the zero position; for 25mm(0.98in) and above, use calibration measurements to align with the zero position. 2. The method of correcting the zero position: if the zero position line is not aligned with the reference line, first loosen the screw with the driver, adjust the position of the reference line with the wrench, and then tighten the screw with the driver. (See Figure 2 of the User manual) 3. When measuring, the micrometer should be kept perpendicular to the workpiece being measured. Rotate the force-measuring device. When the measuring surface comes into contact with the workpiece being measured, gently rotate the force-measuring device. When the force-measuring device emits a slight "click, click..." sound, " The sound time is the actual size of the workpiece being measured. 4. The locking device can passively measure the forward and movement of the micro screw. Relax to the right and lock to the left. (See Figure 3 in the user manual) 5. When measuring, hold the heat insulation plate with your left hand to prevent body temperature from being transferred to the micrometer and causing measurement errors.One end of the wrench can be adjusted to zero, and the other end can be used to tighten the force measurement device.
