1. INTRODUCTION, SPECIFICATIONS AND APPROVALS
This Section provides an overview of the Dynamic Dilution Calibrator, its features, and its
options.
1.1. CALIBRATOR OVERVIEW
Teledyne API’s Model T700 and Model T700U are microprocessor-controlled, dynamic
dilution precision calibrators. The T700U is a modified version of the T700 calibrator, with
the ability to calibrate both standard and trace-level gas analyzers. Both use highly accurate
mass flow controllers, and while an ozone generator, photometer, and gas phase titration
(GPT) chamber are optional in the T700, they are standard in the T700U. Both models
essentially operate the same way and are referred to as “calibrator” or “this instrument” in
this manual, except where they differ, in which case the trace calibrator will be specified
by its model name, T700U.
Using a combination of highly accurate mass flow controllers and compressed sources of
standard gases, the calibrator provides calibration standards for multipoint span and zero
checks. Up to four gas sources may be used.
The calibrator can be equipped with an optional built-in, programmable ozone generator
for accurate, dependable ozone calibrations. The calibrator also produces NO2when
blended with NO gas in the internal GPT chamber. A multi-point linearization curve is
used to control the generator to assure repeatable ozone concentrations. An optional
photometer allows precise control of the ozone generator, both during calibrations and
during GPTs. To ensure accurate NO2output, the calibrator with photometer option
measures the ozone concentration prior to running a GPT.
Many independent calibration sequences may be programmed into the calibrator, 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 calibrator 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 gas calibrators.
1.2. FEATURES
Some of the exceptional features of your calibrator are:
•Advanced T-Series electronics
•LCD color graphics display with touch screen interface
•Microprocessor control for versatility
•Bi-directional USB (optional), RS-232, optional RS-485, and
10/100Base-T Ethernet for remote operation
