3.3.3. OUTPUT MANIFOLD
A four-port output manifold is supplied on the rear panel of the T703 enabling simultaneous testing of up to two
external analyzers. Sample lines for ozone analyzers to be calibrated can be connected directly to this manifold.
To prevent ozone exposure, the bottom port of this manifold is used as a vent and should be connected to a
proper unpressurized vent manifold. It is important that the backpressure at this vent fitting be kept to a
minimum. If a vent line longer than 2 meters (~6 feet) is required, then 3/8” OD tubing should be used.
Any unused ports on this manifold must be capped.
3.3.4. EXHAUST
The port labeled ‘EXHAUST’ contains the exhaust gas from the internal photometer and may contain ozone.
This port should be connected to a proper unpressurized vent manifold to prevent ozone exposure.
3.3.5. MEASURING AN EXTERNAL OZONE SOURCE
The T703 can easily be configured to measure an external source of ozone.
See Section 6.11 for details on operating the T703 in this manner.
