1. INTRODUCTION, SPECIFICATIONS, APPROVALS, &
COMPLIANCE
Teledyne API’s Model N500 CAPS NOx-NO2-NO Analyzer uses Cavity-Attenuated
Phase-Shift (CAPS) spectroscopy to render direct, true measurements of nitrogen dioxide
(NO2). By combining direct NO2measurements with highly efficient gas phase titration
(GPT), the N500 converts and measures the NO sample gas component as NO2, thus
allowing for the measurement of total NOx. Furthering its accuracy and dependability is
an auto-reference cycle to account and compensate for any potential baseline drift in the
measured loss, that may be caused by varying environmental conditions.
CAPS technology is superior to the traditional chemiluminescence method in both speed
and precision since the sampled NO2does not require catalytic conversion to calculate a
difference measurement.
Economically, the Model N500 CAPS NOXinstrument is less costly to operate and
maintain than traditional analyzers in that it uses less power and fewer components.
The section on Principles of Operation provides more detail on the behavior and
technique of the CAPS method for NOXmeasurement.

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 tha
t 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.

14 Teledyne API N500 CAPS NOXAnalyzer with NumaView™ Software 089770000 Rev 05
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.
VENTILATION CLEARANCE
Whether the instrument is set up on a bench or installed in a rack, be sure to leave
sufficient ventilation clearance.
