oxygen concentration.
(1) When instrument air is used for the span calibration, remove the moisture from the instrument air at a
dew-point temperature of -208C and also remove any oily mist and dust from that air.
(2) If dehumidifying is not enough, or if foul air is used, the measurement accuracy will be adversely affected.
