Teledyne API T703/T703U Calibrator Operation Manual Getting Started

OUTPUT MANIFOLD 3.3.3.
A four-port output manifold is supplied on the rear panel of the T703/T703U
enabling simultaneous testing of up to two external instruments. Sample lines for
ozone instruments 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.
EXHAUST 3.3.4.
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.
MEASURING AN EXTERNAL OZONE SOURCE 3.3.5.
The T703/T703U can be configured to measure an external source of ozone.
See Section 4.11 for details on operating the unit in this manner.
3.4. INITIAL OPERATION
If you are unfamiliar with the T703/T703U theory of operation, we recommend
that you read Section 9.
For information on navigating the calibrator‟s software menus, see the menu
trees described in Appendix A.
START-UP 3.4.1.
After all of the electrical and pneumatic connections are made, turn on the
instrument. The exhaust fan and should start immediately. If the instrument is
equipped with an internal photometer installed, the associated pump should also
start up.
The front panel display will show a splash screen and other information during
the initialization process while the CPU loads the operating system, the firmware
and the configuration data.
Once the CPU has completed this activity, it will begin loading the calibrator
firmware and configuration data. During this process, model and software
revision information appear briefly in the Param field of the calibrator‟s front
panel display before the firmware is fully booted:
The calibrator should automatically switch to STANDBY mode after completing
the boot-up sequence.
WARM UP 3.4.2.
The T703/T703U Photometric calibrator requires a minimum of 30 minutes for
all of its internal components to reach a stable operating temperature.
