3.1 The DGA 5000\Geogas 5000
The SUN
®
DGA 5000\GEOGAS5000 is a versatile, high-performance
PC-based test instrument for the analysis of motor vehicle exhaust
gases. The unit is designed to meet the performance requirements of
OIML Class 0 and ISO 3930.
The basic configuration of the unit comprises:
- A gas analysis module containing a NDIR gas bench.
- An rpm/oil temperature module (ROTI) for the measurement
of engine speed and oil temperature.
- An exhaust probe and hose assembly, used for the collection of
the gas sample from the vehicle tailpipe.
The DGA 5000\Geogas 5000 forms part of the Emissions Diagnostic
Platform System.
Specific software versions will be available for performing the emissions
tests specified by separate national or international jurisdictions.
Although this jurisdiction specific software may alter the DGA 5000
standard software described herein, this manual is also applicable to
these specific programs when used in conjunction with the specific
documentation relating to such programs.
With the standard software the unit is capable of measuring the
concentrations of up to five gases in vehicle exhaust emissions:
- Carbon Monoxide, Carbon Dioxide and Hydrocarbons (CO, CO
2
and HC) by infra-red absorption.
- Oxygen (O
2
) by an operator changeable electrochemical cell.
In addition to the gas measurements the unit also displays:
- Lambda (

) according to Brettschneider.
- Engine speed (rpm) via the ROTI module.
- Oil temperature via the ROTI module by means of an oil
temperature probe substituted for the oil dipstick.
