　　2. Quick use

　　After installing the system, please correctly connect the sensor and collector to the corresponding USB port of the computer. Execute Diselab.exe, please maximize the software interface, and check the connection prompt in the lower left corner of the system. If the system is correctly connected to the collector, it will prompt "Connect" ( ). After clicking the arrow there, it will prompt the type of sensor currently connected.

　　If the system cannot be correctly connected to the collector and sensor, please check the hardware connection again (note whether the switch on the side of the sensor box is turned on, and the indicator light is on after turning it on), or re-plug the USB interface cable, etc. If the problem cannot be solved after repeated repetitions, please contact after-sales technical support.

　　After the system is correctly connected to the collector, click "Sensor" in the upper toolbar, a sensor observation window will pop up, and the sensors connected to the collector will be displayed here one by one. If the number or type of the sensor window displayed does not match the actual hardware, please check whether the physical connection between the sensor and the collector is correct.

　　Click the "Start Sampling" button with the mouse, and the system starts to collect data. By default, the system will continuously collect data for 10 seconds at a frequency of 10HZ. The collected data will be displayed in the sensor observation window. Users can click "Type" in the sensor observation window to select different observation methods.

　　The following briefly introduces two data display methods: digital and graphical.

　　1. Digital display mode. Click the sensor icon ( ), the following figure will appear (1)

　　Then select the digital display (this is the most intuitive to see), and then click to show the legend (2).

　　2. Graphic display mode. Click the graphic icon , the following graphic will appear

　　Click on the curve in the left row of the above figure , tick the sensor in front of the sensor (as shown in the figure below), and then click:

　　Click all to zoom automatically , click to start experiment push-pull force sensor, the following figure will be displayed

　　3. Simultaneous display of numbers and graphics. Simultaneous display of numbers and graphics will be more clear. After the above two steps are set, click the top row of the software to select vertical arrangement. You can automatically arrange the two windows as shown below:

　　4. The default sampling frequency of the software is 10hz, and the sampling time is 10s. It can be adjusted through the option menu under the tool menu

　　Click the option to display the following picture: Adjust the frequency under " ",

Adjust the time in the total sampling seconds 　　under " ".

　　After the data collection is completed, you can click the window close button and click "OK" in the confirmation dialog box that pops up to close the system.

　　Three, template and data management

　　1. New

　　Regardless of the current state of the system, if you select the "New" menu, the system will perform the following operations:

If the user wants to set the template or data created by himself as the factory template or data, he only needs to copy the completed template or data to this folder.

　　6. Exit

　　Select this menu item, the system will ask if you want to exit, if you choose to confirm, the system will shut down.
