| Notes: |
Calibration Location: Lab
Last calibration: 2017-03-23
RSSI=72.7%, Optical RH=23%
Ambient P=100.6kPa, Tair=21.8C
Zero Air at 400psi, LBL Air 1.9497 at 1800
CH4 Zero Offset: -0.1ppm
CH4 Span Offset: -0.0197ppm
Notes: Optics RH was 23%, so I flushed the head cavity with zero air and replaced the desiccant. We just changed the desiccant last time (March 2017) so I was expecting a RH ~5%. Let's keep an eye on the optics RH.
