Calibration |
| Notes: |
Calibrated in the lab with god bottle 1.8978ppm CH4 at 180psi. Last calibration Aug 12, 2011. Before running the cal gas the LGR read:
10:33PST, 21.58C, 142.54Torr, 15.466usec, 1Hz, 1.866ppm
I missed writing down the ppm with the cal gas before calibration but it was about 1.80ppm. Afterwards it was right on. |
