Teledyne API T703/T703U Calibrator Operation Manual Introduction
19
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.
