Title: Calibration
Notes: Calibration Location: Mayberry Last calibration: 2020-11-16 RSSI=77%, Optical RH=25% Ambient P=101.0kPa, Tair=27.8C AMP FB03864 at 1200psi, AMP CA04119 4.223 at 2000 CH4 Zero Offset: -0.028ppm CH4 Span Offset: -0.003ppm Notes: Breezy day. Zero gas was an AMP cal gas in a baby tank that we borrowed for the day. After the calibration, we used the zero air to flush the headspace until optics RH = 10%. The drierite was purple, so we swapped in a new bottle with fresh drierite.
