Calibration |
| Notes: |
On 1/27/11, Dennis and Jaclyn tested the LI-7700 output against the calibration gases in the lab.
1. The tank with 4.982 ppm methane read 5.021 ppm on the LI-7700.
2. The zero air tank read 0.05 ppm on the LI-7700 (although low confidence that the gas is in fact zero methane.
3. The 1.8978 god bottle read 1.898 on the LI-7700.
We chose not to calibrate the instrument since the readings were so close to the actual values. |
