Usage:

1. Gently remove the caliper and check if it is in a closed state. Slide the caliper to check if it slides smoothly.

2. Turn on the caliper switch. Press the OFF/ON switch once, and the numerical value will be displayed on the digital display screen. The displayed value is in a normal state.

3. Zero the caliper. The current displayed value is incorrect, so we need to put the caliper in a closed state and press the "reset" button to reset the value to zero.

4. Measure the outer diameter and inner diameter of the object. Hold the object with your left hand and hold the digital caliper with your right hand. Open the caliper, align it with the measuring area, and slowly lock the caliper. At this point, the digital screen will display the size of the object. (Use a digital caliper above to measure the inner diameter)

5. Measure the height of the object. Use the tail of a digital caliper for measurement. First, pull apart a portion of the caliper, place it vertically inside the object, and move it downwards until it reaches the top of the object.

6. Convert units. When you need to convert units, simply press the "mm/inch" button above to freely convert between millimeters and inches.

notice：

1. Before use, wipe the surface of the ruler body with a clean, waterless soft cloth, and do not use organic solvents such as acetone or gasoline.

2. Do not apply voltage to the digital caliper, do not use an electric pen to engrave words, and do not reprocess it with electricity or water, otherwise it may damage electronic components.

3. For daily use, handle with care.

4. When it does not display or flashes, it indicates that the battery voltage is too low. A new battery should be replaced, and the old battery should be recycled according to relevant regulations.
