Connecting Diluent Gas To The Calibrator; Connecting Calibration Source Gas To The T700 Calibrator - Teledyne T700 Operation Manual

Getting Started
1. Determine the Total Flow required by your system by adding the gas flow requirement of
2. Multiply this by 1.5.
3. Decide on a Calibration Gas flow rate.
4. Determine the Calibration Gas ratio by divide the Total Flow by the Calibration Gas Flow
5. Multiply the desired target calibration gas concentration by the result from step 4.
6. 2SLPM + 2SLPM = 4SLPM
7. 4SLPM x 1.5 = 6SLPM = Total Gas Flow Rate
8. If the T700 calibrator so that the cal gas flow rate is 2SLPM (therefore the Diluent Flow
9. 6SLPMm ÷ 2SLPM = 3:1
10. Therefore if your Target Calibration Gas Concentration is intended to be 200 ppm, the
11. 3 x 200ppm = 600 ppm

3.3.2.3. Connecting Diluent Gas to the Calibrator

12. Attach the zero air source line to the port labeled Diluent In.
13. Use the fittings provided with the calibrator to connect the zero air source line.

3.3.2.4. Connecting Calibration Source Gas to the T700 Calibrator

14. Connect the source gas line(s) to the ports labeled CYL1 through CYL4 on the back of

MINIMUM CALIBRATION GAS SOURCE CONCENTRATION
Determining minimum Cal Gas Concentration to determine the minimum concentration
of a calibration gas required by your system:
each of the analyzers in the system.
Rate.
EXAMPLE: Your system has two analyzers each requiring 2SLPM of cal gas flow.
Rate would need to be set at 4 SLPM) the Calibration Gas ratio would be:
minimum required source gas concentration for this system operating at these flow rates
would be:

First, finger tighten.

Then using the properly sized wrench, make an additional 1 and ¼ turn.
the calibrator (see Figure 3-4).

Source gas delivery pressure should be regulated between 25 PSI to 30 PSI.

Use stainless steel tubing with a 1/8 inch outer diameter.
