| Notes: |
Calibration Location: Lab
Last calibration: 2023-06-15
RSSI=91%, Optical RH=21%
Ambient P=100.46kPa, Tair=21.3C
Zero Air at 500psi, AMP CA04119 4.2238 at 750
CH4 Zero Offset: -.03ppm
CH4 Span Offset: -.0188ppm
Notes: This sensor was removed from WP with its decommissioning. 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.
