Back in the lab, it had revert to default heater settings and its clock was off (laptop=11:46, 7700=18:51, "Etc/GMT+8" on slave). I changed the clock setting to automatic, set the clock to match the laptop time, changed the clock setting back to slave, and then rebooted. The time was correct after reboot but we should double-check it after conencting to the 7550 in the field. I changed the heater settings back to our usual. Before calibration, I flushed the optics headspace down to 10% and swapped in a bottle of fresh drierite. |

Ran zero and span gases at our usual flow rate of 2 SCFH and plumbed the system with the recommended 30cm vent before the air inlet to vent excess air pressure and to prevent diffusion of ambient air into the gas stream. I waited until the slope of H2O was <0.002ppm to set the zero. I waited until the slope of CH4 was <0.002ppb to set the span. Plan 45min+ for H2O zero to stabilize. I forgot to write down the exact CH4 span offset, but I saved a screenshot and estimated the offset based on the graph. |
| LI-7550 AIU-1866 | 2023-12-01 | Factory none | Received | Lab none | Received back from Licor. This 7550 sn AIU-1866 went back to Licor for a power problem. Licor replaced the 7550 main power supply under warranty, subjected the units to environmental tests and verified the operation of the units. It was shipped with 7500A sn 75H-2669 (nothing wrong with the 7500A, it was just the sensor attached when the box died) |
| LI-7500A 75H-2669 | 2023-12-01 | Factory none | Received | Lab none | Received back from Licor. It was shipped with LI-7550 sn AIU-1866 which went back to Licor for (another) power board repair. There was nothing wrong with this 7500A sn 75H-2669, but Israel requested we send it back as well b/c it was connected when the LI-7550 broke. Licor replaced the 7550 power supply, subjected the units to environmental tests and verified the operation of the units. |
