Rosemount 6888Xi Electronics or via HART communications to a Field Communicator or AMS console. The technician needs to manually switch the gases based upon these prompts. Emerson recommends using 0.4% O and 8% O , balance nitrogen as calibration gases.
Calibration Instruction Manual July 2018 00809-0100-4891 CAUTION READING ERRORS Make sure the calibration gas cap is replaced tightly after calibration is complete. Many combustion processes operate at a slight negative pressure (draft pressure) and can draw ambient air down the cal gas lines and into the sensing cell, causing a falsely elevated O reading.
