Screen shown in Figure (7), and then select the PCL-726 Advantech / 727/728, and then click "Add" will appear the following screen (Figure (12)), select the PCL-728, to confirm their address as 340

Click 'OK' to complete the installation of the third block of 728. Screen shown in Figure (7), and then select the PCL-726 Advantech / 727/728, and then click "Add" will appear the following screen

(Figure (13)), select the PCL-728, to confirm their address as 340 Click 'OK' to complete the installation of the fourth block 728. Click on the "(7)" and "Close" to end the Advantech A / D card, D

/ A card, I / O card driver installed, this laser software server program is installed. Between the day-to-day operation of the laser-line monitoring system on

working conditions and the external environment in which it has a lot of contradictions; identify the concentration and particle size of catalyst particles, is a monochrome laser, the coherence of

superior performance, but it also has the general characteristics of the light, the use of laser energy attenuation and the emission of energy through the flue gas through quantitative calculation

and qualitative and quantitative to give the desired results; precisely because the laser or light. Therefore, to ensure the transmission of laser energy and the scattering of the laser can only

carry the information of the catalyst particles into the flue gas and escape of smoke, this guarantee is necessary, but also of very great importance, Moreover, also need to know to solve this

guarantee approach. One of these is a quartz glass and the purge air and purge air requirements is clean and purify the wind, air pressure under the premise of ensuring the flow, it is best to

0.3MPa ~ 0.4Mpa; quartz glass contamination of the laser through the light and astigmatism light can have a huge impact, thus affecting the accuracy of the calculation of concentration, etc..
The Y-axis of the vertical movement of the curve: Click on the graph title bar, scroll so that it turns yellow, and then click on the curve and hold the left mouse button to move up and down

curves. Horizontal scaling curve: Click on the X-axis of the curve diagram of the title bar to zoom in to turn yellow, then click the curve to hold down the left mouse button and sliding around can

zoom in or out the timeline of the curve. Y-axis vertical scaling curve: Click on the title bar of the curve to enlarge it turns yellow, then click the curve to hold down the left mouse button to

slide up and down to make the Y-axis value of the curve to zoom in or out. Cursor positioning: position the cursor click on the title bar of the graph, it turns yellow, and a vertical yellow lines

in the graph, move the vertical bar.
