Wipe the claws with a soft cloth and bring them together to see if the zero mark of the cursor and the main ruler are aligned. If the alignment is made, the measurement can be made: if there is no alignment, the zero error is recorded: the zero mark of the cursor is called the positive zero error on the right side of the zero mark of the ruler, and the negative zero error on the left side of the zero mark of the ruler (this is called The specification method is consistent with the specification of the number axis. The origin is positive to the right and the origin is negative to the left). When measuring, hold the ruler with your right hand, move the cursor with your thumb, and take the object of the outer diameter (or inner diameter) to be measured with your left hand so that the object to be tested is located between the outer measurement claws. When it is closely attached to the claws, The reading, as shown in the figure below: When measuring the outer dimensions of the part: the line connecting the two measuring faces of the caliper should be perpendicular to the surface to be measured and should not be skewed. When measuring, you can gently shake the caliper and place it in a vertical position, as shown in Figure 2-6. Otherwise, if the measuring claw is in the wrong position as shown in Fig. 2-6, the measuring result a will be larger than the actual size b; firstly, the movable claw of the caliper is opened, so that the measuring claw can be freely stuck into the workpiece. Place the part against a fixed amount of claws, then move the frame and use light pressure to bring the movable jaws into contact with the part. If the caliper has a micro-motion device, the fixing screw on the micro-motion device can be tightened at this time, and then the adjusting nut is rotated to make the measuring claw contact the part and read the size. Never adjust the two jaws of the caliper to be close to or even smaller than the measured size, forcing the caliper to the part. Doing so will deform the jaws or cause premature wear on the measuring surface, causing the caliper to lose its proper accuracy.
How to use the vernier caliper
The above is an introduction to the vernier caliper, including its readings, methods of use, and its application. Since the vernier caliper is a relatively sophisticated measuring tool, it has been widely used in industrial measurement lengths, with the development of science and technology and the industry continues to grow. The digitization of inspection instruments is a general trend of current and future instruments, and the measurement efficiency of workpieces is also required to be higher and higher. The current internal quality inspection method of the factory is to measure the data manually, and the measurement personnel manually record in the paper, or one person measures, and the other person performs the recording operation mode. When the analysis is needed, the operator inputs the data to the computer. In the EXCEL table; the problem caused by this traditional measurement method is that the efficiency is low and the data is easy to remember. In response to this situation, a method for efficiently measuring the length of the vernier caliper has been promoted. Only by using our data acquisition instrument to connect to the vernier caliper, the acquisition instrument will automatically obtain measurement data from the vernier caliper for recording, analysis and calculation. Corresponding various types of graphics, automatic judgment of measurement results, etc., this method truly realizes the measurement of data, not only can reduce the error caused by manual measurement, but also can greatly improve the measurement efficiency.
