4) After the device is connected, open the software, wait for the software to automatically identify, the laser and the spectrometer automatically display a string of characters or main letters, the status is "connected", then the recognition is successful, the "center wavelength" is set to the corresponding device wavelength, such as the center wavelength of Portman785 is "785", the laser type is selected "on-board laser interface". Select Raman Shift for the horizontal coordinate, as shown in Figure 3-5
5) If the connection is not displayed, you can also click "Spectrometer Setup - Scanning Device" in the upper right corner to scan and identify the Settings or check whether the data cable is properly connected and the driver is properly installed, as shown in Figure 3-6
6) On the Device page, you can set spectrum collection conditions, such as Power, Integration Time, and Average Times, and set the average mode to Hardware Computing Average, as shown in Figure 3-7. Default Settings: Light items set 100mW, 1000ms; Dark objects are easy to burn, set 50mW, 1000ms. Then adjust according to the sample and signal conditions.
7) After setting the conditions, select "Laser automatic" and click "Single" or "continuous" collection to start the test, as shown in Figure 3-8
8) Three kinds of legends can be selected. "Original spectrum" is the spectrum without deducting the baseline, "background" is the spectrum after deducting the baseline, and "processed spectrum" is the spectrum after algorithmic processing, making the lowest point of the spectrum around 0, as shown in Figure 3-9:
9) Three coordinate modes can be selected, "Maximized" horizontal and vertical coordinates are the maximum display, "Adaptive display" can adjust the spectrum to the most easily observed position, "Custom" can manually set the range of horizontal and vertical coordinates, as shown in Figure 3-10
10) Save the tested data. "Quick Save" is generally saved to the desktop by default and named after the current time. You can also find it in "Record" on the left and rename it, as shown in Figure 3-11 and 3-12
11) Click "Export Data" (as shown in Figure 3-13) to export the data into a file, and a pop-up box will be displayed as shown in Figure 3-14. Generally, select "Export without interpolation data" to generate a file to save the data to the specified location, and name the file, which is generally named after the current test sample and test conditions, in case the next import forgets the test conditions. For example, "Original spectrum - ethanol -500mW-100ms- average 5 times", the file type is selected.csv;.
12) Click "Import Spectrum" to import the previously saved.CSV file into the software for display, click "File-copy data" to copy the current data and paste it into an Excel table or input box, or click "File-Save as picture" to save the current spectrum as a picture, as shown in Figure 3-15
13) You can build your own database, first test a standard product and "add it to the database", then take a sample of the same type for testing, and click "identification detection" to identify the sample after the test is completed, as shown in Figure 3-16.
Note: The default power and integration time for the first use is 100mW, 1000ms for light samples; Dark samples are easy to burn, set to 50mW, 1000ms. Then adjust the focal length and parameters to find the best position of the signal.
2.3 The use of mobile APP
1) First install the mobile version of the test APP, and connect the spectrometer to the mobile phone with a data cable, as shown in Figure 3-17
2) First, open the login interface, click the three dots in the upper right corner, set the serial number and network parameters, the serial number is A101, and the IP address is changed to stdold.oceanhood.com, as shown in Figure 3-18 and Figure 3-19
3) Select Network Account, the user name is kh, and the password is 123456Aa, as shown in Figure 3-20

6) You can upload the mobile phone test data to the computer, first convert the mobile phone test data into a file, find a folder named "OH" in the mobile phone file management, find out the saved data, and then send it to the computer for processing through wechat, QQ, Dingding, etc., as shown in Figure 3-24.
2.4 Experimental operation
1) Solid
1. Sample preparation
2. Equipment preparation: Prepare Raman spectrometer FLRaman3, data line, one-dimensional Z-axis adjustable bracket, Raman probe cap, computer or mobile phone
3. The Z-axis adjustable support is equipped to measure solids, and the sample is fixed on the support, as shown in Figure 3-27. The data cable is connected to the spectrometer and the computer, as shown in Figure 3-28.
4. Install probe caps to test solids, as shown in 3-29. Put the probe caps on the probe and keep close to the sample, as shown in Figure 3-30 and Figure 3-31.
5. Open the software, adjust the focal length, set the test conditions, conduct the test, and save the data.
2) liquid
1. Sample preparation: Put the liquid in a transparent container, as shown in Figure 3-32
2. Equipment preparation: Raman spectrometer FLRaman3, data line, liquid measurement stand, computer or mobile phone
3. As shown in Figure 3-33, point the probe at the sample and keep the distance about 7.5mm.
Note: Never wear the probe cap against the sample bottle, so that the signal is the sample bottle and not the liquid signal.
4. For liquid measurement with a stand, as shown in Figure 3-34, first connect the spectrometer with the computer (mobile phone), put the glass bottle or comparator with liquid into the liquid measurement tank, and then put the probe of the spectrometer directly into the entrance on the side of the measurement tank
