Press "Add Gases" to define what gases will be a part of this gas mix. Remember that gases should be
zeroed and then spanned. With this basic rule this span gas for this example will be defined for H
not for any other gases. Press the
operation of the pump. As a general rule, if the gas is in a calibration gas cylinder then this should be set
to 'Manual'. If the gas is atmospheric or in a non-pressurized container such as a Tedlar bag then the
pump should be set to 'Automatic'. Irrespective of the pump definition in the Gas Mix setup, it can be
overridden while checking and calibrating with gases.
