. When using the ZO21S Standard Gas Unit (for use of the atmospheric air as a
span gas), use a hand-held oxygen analyzer to measure the actual oxygen concentration,
and then enter it.
CAUTION
If instrument air is used for the span gas, dehumidify the air to a dew point of -20°C and remove
any oil mist or dust.
Incomplete dehumidifying or unclean air will have an adverse effect on the measurement
