This section provides a description of the set-up of the analyzer. When using the analyzer for the first
time, check for any damage that may have occurred during shipping. We suggest filling out the
Instrument ID Sheet at the back of this manual for your permanent records.
Please familiarize yourself with the front and back panels of the unit by examining the unit and the
pictures on the following pages.

The analyzer can be operated from AC power source at 110-120 VAC or 220-240 VAC (12VDC or
24VDC optional). The AC power-input connection is a standard 3-wire recessed computer-type
connector. Various types of power cords may be used to connect to wall power as needed to be
compatible with the various supply voltages and wall sockets throughout the world.
Attach the power cord to the rear of the analyzer and plug the end of the cord into the appropriate
main power.
Make sure that the sample probe or line has been placed in an area where there is only clean dry air to
be drawn into the sample line or, if using an external sample conditioner, that the sampling selector
switch is set to “ZERO”.
Connect the sampling conditioners output line to the inlet port on the back of the analyzer.
Press the Power button to turn on the unit.
The front panel will then display the Infrared Industries logo while the analyzer is starting up. The
warm-up time will vary depending on analyzer’s internal temperature. Zero gas should flow
continuously during warm-up; if not, the accuracy of the analyzer maybe significantly reduced.
Once the analyzer is warmed-up, it is ready to begin measuring gas concentrations. Select the sample
line you wish to measure and turn on your sample conditioner sample pump. Allow a few seconds for
the gases to reach the analyzer and for the displayed values to stabilize.
Optional Automated Zero:
With the automated zeroing feature option; it is necessary to add an additional supply line from your
Zero gas (N2) cylinder and connect it to the “Zero” port on the back of your analyzer. This line will
supply the Zero gas to the automated solenoid valve located inside the analyzer. This feature allows
the operator to perform a zero from the front panel of the analyzer. When the zero is engaged; the
sample port to the analyzer will close and zero port will open allowing your zero gas to purge the
analyzer and then “ZERO” the analyzer. After the zero is completed; the zero port will close and the
sample port will again open and begin reading the sample stream.
