This section specifies the requirements to set up an Oxymitter 4000 calibration and how to verify the calibration gas flow setup. It also explains the differences between automatic and semi-automatic calibrations and how to initiate them.

Calibration Gas Tanks

Two tanks of precision calibration gas mixtures are required. Recommended calibration gases are nominally 0.4% and 8.0% oxygen in nitrogen.

Do not use 100% nitrogen as a low gas (zero gas). It is suggested that gas for the low (zero) be between 0.4% and 2.0% O2. Do not use gases with hydrocarbon concentrations of more than 40 parts per million. Failure to use proper gases will result in erroneous readings.
