1. INTRODUCTION
This manual provides information and operation instructions for the Model T703
and the Model T703U calibrators. For simplicity the information and instructions
in this manual refer to both models except where the Model T703U diverges in
technical or operational aspects, in which case the T703U is clearly defined.
1.1. T703/T703U CALIBRATOR OVERVIEW
The Model T703 and the T703U are microprocessor controlled ozone calibrators
for calibration of precision ambient ozone instruments, such as the TAPI T400.
They feature an internal ozone photometer that provides very accurate closed
loop feedback control of the ozone concentration. However, the T703U is capable
of generating ozone in a low range (fractional mode), for ultra-low ozone
production.
As many as 50 independent calibration sequences may be programmed into the
T703/T703U, covering time periods of up to one year. The setup of sequences is
simple and intuitive. These sequences may be actuated manually, automatically,
or by a remote signal. The sequences may be uploaded remotely, including
remote editing. All programs are maintained in non-volatile memory.
The T703/T703U design emphasizes fast response, repeatability, overall accuracy
and ease of operation. It may be combined with the Model 701 Zero Air
Generator to provide the ultimate in easy to use, precise calibration for your
ozone instruments.
Some of the exceptional features of your T703/T703U Photometric O3Calibrator
are:
•Advanced T-Series electronics
•LCD Graphical User Interface with capacitive touch screen
•Bi directional RS-232 and 10/100Base-T Ethernet, optional USB and RS-
485, ports for remote operation
•Front panel USB ports for peripheral devices
•12 independent timers for sequences
•Nested sequences (up to 5 levels)
•Internal ozone generator and photometer allows use as primary or transfer
standard
•UV Lamp Feedback modes: current control; photometer control
•Lightweight for transportability
•T703U: ultra-low ozone production down to 3ppb

95C Calibration to NIST-SRP
95D Calibration as a Transfer Standard (6x6)
The Model T703 can be used as a Primary Ozone Standard. For this application the performance of the T703 Photometric
Calibrator is calibrated to Standard Reference Photometer (SRP) Calibrators ordered with this option are verified and
validated in accordance with the procedures prescribed by the U.S. Environmental Protection Agency (EPA) under Title 40
of the Code of Federal Regulations, Part 50, Appendix D (40 CFR Part 50).
Special Features
Built in features, software activated
N/A
Maintenance Mode Switch, located inside the instrument, places the analyzer in
maintenance mode where it can continue sampling, yet ignore calibration, diagnostic, and
reset instrument commands. This feature is of particular use for instruments connected to
Multidrop or Hessen protocol networks.
Call Technical Support for activation.
N/A Second Language Switch activates an alternate set of display messages in a language
other than the instrument’s default language.
Call Technical Support for a specially programmed Disk on Module containing the second language.
