SPAN GAS/ZERO AIR CALIBRATION MANIFOLD EXHAUST/VENT LINES
The span and zero air manifolds‟ excess gas should be vented to a suitable vent outside
of the room. This vent should be of large enough internal diameter to avoid any
appreciable pressure drop, and it must be located sufficiently downstream of the output
ports to assure that no ambient air enters the manifold due to eddy currents or back
diffusion.

Figure 3-25: T700 Pneumatic Diagram – Base Unit
The standard T700 Dynamic Dilution Calibrator is equipped with one calibration gas
mass flow controller (flow rate 0 – 100 cm
controller (flow rate 0-10 LPM). See Table 1-1 for the various flow rate options.
Some of the T700 Dynamic Dilution Calibrator‟s optional equipment requires additional
pneumatic connections.
