ONNECTING THE
Using a calibration manifold provides a pneumatic interface between the calibration system
and other devices (or systems) which use the calibrator's gas output. Calibration manifolds
usually have one or more ports for connections to other external devices (such as an
analyzer).

• This method requires the analyzers connected to the
calibration system have internal zero/span valves.
• The manifold should be kept as clean as possible to avoid loss
of sample gas flow from blockages or constrictions.
• The manifolds as shown in the above drawing are oriented to
simplify the drawing. Their actual orientation in your set-up is
with the ports facing upward. All unused ports must be
capped.
• When initiating calibration, wait a minimum of 15 minutes for
the calibrator to flood the entire calibration manifold with
calibration gas.
