Endothermic

The effectiveness of the catalyst is measured by the CH4 content. Less than 0.5% is an indication of properly functioning catalyst. Higher concentrations indicate the necessity for either conditioning or replacement.
Measuring the level of CO in the carrier gas allows for correction of the % Carbon reading at the furnace.

Heat Treat Conventional

Furnace atmosphere Carbon potential (% C) can be verified with the PGA 3510
Measuring Carbon Monoxide (CO) allows for adjustment of the COF/PF parameters to fine tune the % Carbon calculation in the furnace
Measuring Carbon Monoxide (CO) and Carbon Dioxide (CO2) can show possible problems (i.e. sooting, water leaks, air leaks, and radiant tube leaks)
Too much free Methane (CH4) could be an early indication of a furnace problem

Heat Treat Nitrogen/Methanol Endo

The carbon monoxide (CO) level in the furnace atmosphere indicates the effectiveness of the cracking of the methanol. Equilibrium of this reaction
CH3OH --> CO + 2H2 is temperature dependent
Furnace atmosphere carbon potential (% C) can be verified with the PGA 3510
Measuring carbon monoxide (CO) allows adjustment of the COF/PF parameters to fine tune the % Carbon calculation in the furnace
Measuring Carbon Monoxide (CO) and Carbon Dioxide (CO2) can show possible problems (i.e. sooting, water leaks, air leaks, and radiant tube leaks)

(Q9) How often should I calibrate the PGA?

If the device is used...Then perform a calibration...
DailyWeekly
WeeklyMonthly
Less than weeklyPrior to use

(Q10) How much flow do I need to get a good sample?

SSi recommends 1.5 scfh.  However, anywhere from 1 – 2 scfh is acceptable.

(Q12) What are the IR shim and CH4 factors?

These are factors that go into the calculation for determining the %Carbon. Manually adjusting them will have a direct effect on the %Carbon being calculated.  Contact SSi for more information.

(Q14) How do I set the Device time on the PGA?

To set the Device time to match the Touch screen date and time:

  1. Go to Menu and log in with the number 2.
  2. Then select “Instrument set up” > “General set up.”
  3. Edit the Device time to match the touch screen time by selecting “Device Time” > “Edit.”

(Q15) How do I get Nitriding calculations on my PGA?

  1. Call SSi  at 513-772-0060 for a Code of the Day login number.
  2. Log in with the code.
  3. Select the “Factory use only” option.
  4. On the following screen select “Set Instrument Type.”
  5. Set the Nitrider Calculations option to Enable.
  6. You will then need to cycle power to have the correct Calculations page displayed.

(Q16) Can my PGA do Dew point?

The PGA displays a calculated dew point using gas values and requires assumptions regarding the composition of the gas being sampled. Since these assumptions are not always accurate, the resulting dew point is not always accurate.

(Q19) What is the recommended pressure for calibration gases?

The incoming pressurized gas goes through a small fixed orifice inside the analyzer, which should require between 20 and 50 psi to maintain proper flow.

(Q23) How do I use the CO2 scrubber for calibrations?

  1. Remove the end caps from each side of the CO2 Scrubber.
  2. Go to the calibration screen of the PGA and turn the pump ON.
  3. Attach either end of the CO2 scrubber to the inlet tube of the PGA.
  4. Watch the zero calibration values until they drop to near 0.00%.
  5. Select “Start Calibration” and allow the green progress bar to start.
  6. Once complete, turn the pump off and then connect to your Span calibration gas.

(Q24) How do I create and start a Session?

  1. On the PGA , go to Menu and log in with the number 2.
  2. Then select “Tools” > “Database maintenance.”
  3. On this screen you can maintain equipment, users, and manage the equipment and sessions.
  4. Go back to the main menu and select “Sessions” to allow you to select your Operator, Equipment, and start the session.

(Q25) How do I connect to XGA viewer software?

SSi recommends using the included USB cable as follows:

  1. On your PC, open the installed XGA Viewer (make sure your PGA is also turned on).
  2. Using the provided USB cable, connect the B Connector to the “Client” port on the side of the PGA and the A connector to the PC.
  3. In XGA Viewer select “Options” > “Instruments set up.”  This will open a Configure Analyzers window.
  4. On the bottom select “Add.” Here you can name the instrument and enter its serial number.
  5. Click the blue “Scan” button to scan the Network for your PGA.
  6. When the scan is completed you should see the PGA appear.  Click on it.
  7. You will be returned to the Configure Analyzers window.  Click “Save.”

(Q27) When should I change the sample tube filter?

Whenever you see the inside of the filter start to change color. The filter can be replaced by changing p/n 31033.
