  1. Log in to computer, go into 'Process Eye Professional' 
  2. Click on 'Recipe List', then click on 'Easy View'
  3. The RGA connected to computer through ethernet will have a distinct filled in symbol to its left. 
    1. This will open up an EasyView tab of respective RGA device
    2. If the device does not automatically connect, refer to this how-to document: https://confluence.slac.stanford.edu/x/dRoEEw
  4. Turn on the filament, and select analog data view (see section 10 of HPS document for more details on Process Eye Professional).
  5. Collect data for 5 minutes at accuracy 5 before continuing. At Accuracy of 3 is fine.
  6. Note the pressure at the cold cathode. Slowly open the leak valve until the pressure slowly starts to rise. Keep opening the leak valve until the pressure at the cold cathode reads 1e-6 torr.
    1. At this point the 28 AMU (nitrogen) should be the highest peak in the RGA scan.
  7. Open a bar graph and use the marker tool to select all the highest peaks on the graph. At accuracy of 6.
    1. Input the values to the provided spreadsheet to get the pressure that the RGA thinks it sees and to then get the percentage of the total pressure the nitrogen provides
    2. Spreadsheet: https://docs.google.com/spreadsheets/d/15D6ebvvUcVcYYJx70cF8eDa5uTvCGoae9l0nPlBS-ts/edit?usp=sharing 
      1. Example on Cart 2 Tab, at the top (reference Figure 3). Copy & paste calibration example to desired spot
  8. BEGIN CALIBRATION
    1. If you have issues connecting to RGA, or get following error, ensure RGA labeled IP matches the IP that ProcessEye assumed IP.
      1. If not, you will need to go into RGA Device Manager, and reconfigure the RGA
        1. 'Configure' Tab>Click on desired RGA>Insert (IP:Label IP)(Subnet: 255.255.0) (Gateway: Leave Empty)

Step 1: Faraday Calibration
