Analyzer Set-up
This section provides a description of the set-up of the analyzer. When setting up the analyzer for the first time check
for any damage that may have occurred during shipment.
P O W E R U P
The analyzer can be operated from either AC or DC power sources. For AC connections the analyzer will accept 90 –
260 VDC. For DC the analyzer will run off 10-16VDC.
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. Each will have a different connector to be compatible with the various
supply voltages and wall sockets.
Attach the power cord to the rear of the analyzer and plug the end of the cord into the appropriate power source. The
12VDC cable can be plugged into a cigarette lighter or battery for the power source. Make sure that the sample probe
has been placed in an area where there is only air to be drawn into the sample line. Press the Power button to turn on
the unit
In the first 5 seconds, all display segments and indicators will light in order to make sure they are functional. The front
panel will then display PLEASE STAND BY while the analyzer is warming up. The warm-up times may vary
depending on analyzer’s internal temperature. The Zero and Pump indicators will be on during approximately 30
seconds after warm-up period. Do not attempt to flow any gases into the analyzer through the CAL port. This will
severely affect the accuracy of the analyzer.
After the warm-up cycle is completed and the probe is in the tailpipe, press the MEASURE key to begin
measurements.
Note: Check the flow indicator to make sure you have sufficient flow; the indicator should be all green.
Once the analyzer is warmed up, you can begin measuring gas concentrations by connecting the sampling hose/probe
assembly to the inlet port located on the filter in the back of the analyzer. Insert sampling probe to a gas source or an
exhaust stream. Press the Measure button [6] to begin sampling of the gases. Allow a few seconds for the gases to
reach the analyzer. While in measure mode, you can hold or freeze the display values by pressing the Hold button [8]
as displayed in chapter 3.
