One-button measuring instrument is an efficient and accurate measuring tool, which is widely used in various industrial measuring fields. In order to ensure the accuracy of the measurement results and the long-term stable operation of the instrument, the following are the detailed steps and precautions for the correct use of the one-button measuring instrument:

1. Preparation before use
1. Placement and connection:

1. Place the one-button measuring instrument on a stable, vibration-free platform, ensure that it is well connected to the power adapter, and confirm that the power supply is normal.

2. Insert the measuring marker according to the instructions and ensure that the measuring marker is on the same plane as the measuring area.

2. Software installation and connection:

1. Turn on the computer, connect the measuring instrument to the computer via USB cable, and ensure that the camera is correctly recognized by the computer.

2. Download and install the control software of the measuring instrument. After starting the software, click the "Connect Device" button, select the correct device port, and click "OK".

2. Measurement operation
1. Create a new project and import images:

1. In the software interface, click the "New item" button to create a new measurement item.

2. Click the "Import Image" button, select the image file to be measured, and click "OK". Ensure that the image is clear, without blurring or distortion.

2. Set reference points and feature points:

1. In the image display window, click the reference points on the image with the left mouse button. These points will be used for calibration and positioning.

2. In the "Select Object" menu, select the feature points to be measured. These points are usually the key dimensions or shape features of the object to be measured.

3. Identify features and measure:

1. Click the "Identify Features" button and wait for the software to automatically locate and mark the feature points. If the identification is not accurate, you can manually adjust or re-select the feature points.

2. In the software interface, click the "Measurement" button, and the software will automatically analyze the image and display the measured value in the measurement result window.

3. Data processing and storage
1. Export data or pictures:

1. If necessary, you can choose to export measurement data or pictures for further analysis or archiving.

2. When exporting data, select an appropriate format (such as PDF, DOC, XLS, TXT, etc.) and ensure the accuracy and integrity of the data.

2. Check and save:

1. In order to ensure the accuracy of measurement, an object of known size can be used for calibration. Place a ruler of known size in the same measurement area, and click the "Check" button in the software interface. The software will automatically identify the scale and compare it with the measurement results to provide verification results.

2. After all measurements are completed, click the "Save" button in the software interface to save the measurement data to the specified path.

Iv. Precautions and maintenance
1. Environmental conditions:

1. During the measurement period, keep the ambient temperature constant to avoid the impact of temperature changes on the measurement results.

2. Avoid using a one-button measuring instrument in a humid, dusty or strong magnetic field environment.

2. Power supply and cable:

1. Use the one-click measuring instrument under the correct power supply voltage to avoid faults caused by voltage fluctuations or instability.

2. Do not bend the AC power cable assembly forcibly or place heavy objects on the assembly to avoid cable damage.

3. Safe operation:

1. Do not remove the cover or disassemble the instrument to avoid touching the inside of the product and causing electric shock.

2. Do not put your hand between the platform or between the platform and the variable lighting device to avoid being hurt.

4. Regular cleaning and maintenance:

1. Regularly clean the key components of the equipment, such as optical components and measurement platforms, to maintain the high performance of the equipment.

2. Wipe the surface of the instrument with lens paper or dry cloth, avoid using diluent or organic solvent.

To sum up, the correct use of the one-button measuring instrument needs to follow certain steps and precautions. Through reasonable operation and maintenance, the accuracy of measurement results and long-term stable operation of the instrument can be ensured.
