________________________________________________________________F-900 Instruction Manual rev. 4/2/2015 Alternatively, a CO2 scrubber such as soda lime can be placed in Chamber OUT. In this case, use the following settings. SETTINGS Chamber OUT Chamber IN Closed Loop Set zeros On Off On CO2 Uptime 01:15 Bat 75% Turn the ethylene (C2H4) sensors on for the CO2 calibration. Directions for using a buffer system in place of a standard gas may be found at the end of the section. Figure 14: Calibrating the CO2 sensor using standardized gas. The CO2 PPM (IRGA) zero calibration will drift with time and temperature therefore weekly calibration is recommended when using the CO2 PPM sensor. If performing the CO2 span calibration, it should be carried out immediately after the CO2 zero calibration. The CO2 span or gain calibration does NOT need to be performed every time the CO2 zero is set. When performing the CO2 span calibration, use standardized gas with at least 100 ppm CO2, but not over the range of the CO2 sensor (2000 ppm or 3000 ppm, check the production test check sheet at 1554 NE 3rd Ave, Camas, WA 98607, USA [email protected] Phone (360) 833-8835 Fax (360) 833-1914 http://www.felixinstruments.com 37
