Calibration |
| Notes: |
All was running. The LGR read:
9:04PST, 31.36C, 97.41Torr, 13.973usec, 10Hz, 2.964ppm
I calibrated the LGR with secondary tank with 3.276ppm CH4 at 250psi. Last cal was 2011-11-22
Pre cal: 9:12PST, 30.18C, 124.54Torr, 13.972usec, 1Hz, 3.200ppm
Pressure was a little low but okay. After cal the LGR read 3.271ppm. I adjusted the bypass valve to bring the pressure to 146Torr in high flow mode. I returned the LGR to 10Hz before leaving. |
