Introduction
The analyzer allows the measurement of four or five gases in automotive exhaust. It is capable of determining volume
concentrations of HC (as N-hexane), CO (carbon monoxide), CO
2
(carbon dioxide), O
2
(oxygen), and optionally NOx
(nitric oxide).
Based on gas concentrations the analyzer will calculate the Air to Fuel Ration (AFR), Lambda (
) and Grams per Mile
(GPM) or Grams per Kilometer. It will also provide a read-out for the optional Tachometer that handles up to 30,000
RPM. With this much information in one place, you can diagnose and tune any fuel-related issues while having all of
the relevant information displayed in six super-bright, oversized displays.
All of the above is available as analog outputs in either 0 - 5VDC or 0 - 10VDC for interfacing to a data acquisition
system.
In addition to the above you features; the analyzer can measure exhaust gases from two tail pipes and average the
readings, or set up an exhaust dilution value to warn you if there are air-leaks in the exhaust system.
The analyzer is fully portable. Weighing only
9 pounds the unit is intended for use in a variety of indoor or outdoor
environments. The analyzer can be plugged into standard power outlet voltages ranging from 90 VAC or 260 VAC,
50/60 Hz. You can connect the FGA4000XDS to the car battery or cigarette lighter and take it along for a drive test
to see how the vehicle behaves in real driving situations. Using the internal record feature you can store the data during
the drive test and playback or download the information to a POC when you return.
