Step 2. Open the Site Master Software Tools program.

Step 3. Double-click on the “Site Master Software Tools” icon to open the program.

Step 4. Click on Capture, in the top menu bar, and select Capture Plots To Database from the drop-down menu.

Step 5. Follow the database instructions to download the plot(s) to either a new database or an existing database.

Step 6. Enter the number(s) of the stored-display memory location(s) (1 to 200) from which you wish to store to the database, and click OK.

Step 7. Observe that the “Acquiring Control” box appears on the screen, then disappears as traces are automatically acquired. The “Database” box appears when the plot(s) has been completely captured into the database.

Capture single or multiple traces to PC screen

Step 1. Perform steps 1, 2, and 3 of the capture-multiple-traces-to-database procedure.

Step 2. Click on the Start Plot Capture icon or click on Capture, in the top menu bar, and select Capture Plots to Screen from the drop-down menu.

Step 3. Enter the number (or numbers) of the stored-display memory location(s) (1 to 200) from which you wish to display traces in Site Master Software Tools.

Step 4. Select OK.

Step 5. Observe that the “Acquiring Control” box appears on the screen, then disappears as the traces are automatically acquired and displayed.
