1. INTRODUCTION, SPECIFICATIONS, APPROVALS, &
COMPLIANCE
Teledyne API’s Model T500U CAPS NO2Analyzer uses Cavity-Attenuated Phase-Shift
(CAPS) spectroscopy to render direct, true measurements of nitrogen dioxide (NO2). This
technology eliminates the need for catalytic conversion or reagents that then introduce
measurement artifacts from traditional heated metal converter-based chemiluminescence
instruments The T500U operates as an optical absorption spectrometer, wherein the
absorbance (lost light) is directly proportional to the path-length and the concentration of
the absorbing gas (Beer-Lambert law), providing direct measurement of NO2.
The T500U uses few components: an optical cell, a pair of highly reflective spherical
mirrors centered at 450nm (strong NO2absorbance band), a light emitting diode (LED),
and a vacuum photodiode detector. The LED is located behind a mirror at one end of the
cell, and the detector behind the other mirror at the opposite end of the cell. The LED emits
ultraviolet light (UV) into the cell; the light reflects back and forth between the two mirrors,
building intensity and running a very long path length. The long path length extends the
“time” or “life” of the photon, thus providing ample time to measure absorbance when NO2
is present. Through the use of precisely timed data acquisition coupled with a proprietary
algorithm the measured absorption is translated into a phase shift, from which the NO2
concentration is calculated. The phase shift decreases as the NO2signal increases.
The CAPS method is faster than the traditional chemiluminescence method since the
sample does not require cycling through a catalytic converter to calculate a difference
measurement. Its speed also makes measurement more precise due to the ability to capture
samples closer to “real time” before ventilation vortices (e.g., urban canyons and other
traffic-related forces) can scatter the concentration.
Economically, the Model T500U CAPS method is less costly to operate than traditional
analyzers in that it uses less power (~80W) and fewer components.
The section on Principles of Operation provides more detail on the behavior and technique
of the CAPS method for NO2measurement.

2. GETTING STARTED
This section addresses unpacking, connecting, and initializing the instrument, getting an
overview of the menu system, and setting up/configuring the functions.
UNPACKING
CAUTION - GENERAL SAFETY HAZARD
To avoid personal injury, always use two persons to lift and
carry the analyzer.
ATTENTION
COULD DAMAGE INSTRUMENT AND VOID WARRANTY
Printed Circuit Assemblies (PCAs) are sensitive to electro-static
discharges too small to be felt by the human nervous system. Failure
to use Electro-Static Discharge (ESD) protection when working with
electronic assemblies will void the instrument warranty. Refer to the
manual, Fundamentals of ESD, PN 04786, which can be downloaded
from our website at http://www.teledyne-api.com.
ATTENTION
COULD DAMAGE INSTRUMENT AND VOID WARRANTY
Do not operate this instrument without first removing dust plugs from
SAMPLE and EXHAUST ports on the rear panel.
Note
Teledyne API recommends that you store shipping containers
and
materials for future use if/when the instrument should be
returned to the factory for repair and/or calibration service. See
Warranty statement in this manual and Return Merchandise
Authorization (RMA) on our Website at http://www.teledyne-
api.com.
Verify that there is no apparent external shipping damage. If damage has occurred, please
advise the shipper first, then Teledyne API.
Included with your instrument is a printed record of the final performance characterization
performed on your instrument at the factory. This record, titled Final Test and Validation
Data Sheet, is an important quality assurance and calibration record and should be placed
in the quality records file for this instrument.

With no power to the unit, carefully remove the top cover of the instrument and check for
internal shipping damage by carrying out the following steps:
1. Carefully remove the top cover and check for internal shipping damage.
a. Remove the screws located on the instrument’s sides.
b. Slide the cover backward until it clears the instrument’s front bezel.
c. Lift the cover straight up.
2. Inspect the interior of the instrument to ensure all circuit boards and other
components are intact and securely seated.
3. Check the connectors of the various internal wiring harnesses and
pneumatic hoses to ensure they are firmly and securely seated.
4. Verify that all of the optional hardware ordered with the unit has been
installed. These are listed on the paperwork accompanying the instrument.
WARNING – ELECTRICAL SHOCK HAZARD
Never disconnect PCAs, wiring harnesses or electronic
subassemblies while under power.
