3 Introduction
3.1 The DGA 2500
The SUN® DGA 2500 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 1 and 0
and ISO 3930.
The basic configuration of the unit comprises:
- A gas analysis module containing a Siemens “Sibench” gas
bench.
- A rpm/oil temperature module (ROTI) for the measurement of
engine speed and oil temperature. The unit is supplied with a
Grey inductive pick-up (P/N EAX0048E03A; for use with
conventional HT ignition systems) as standard equipment.
- An exhaust probe and hose assembly, used for the collection of
the gas sample from the vehicle tailpipe.
The DGA 2500 forms part of the SUN
Refer to the SUN
Diagnostic Platform’) for an introduction to the system as a whole.
The addition of an optional USB to 4 x RS232 connector enables a
smoke module, for testing diesel emissions, and a Portable Data Link,
used to obtain information from the vehicle engine management system,
to be connected to the system via the Gas Analyser. This connector can
also be used for external communication with, for example, the
customer’s central computer 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 2500
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.

C H A P T E R 3 INTRODUCTION
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
and HC) by infra red absorption.
- Oxygen (O
- Oxides of Nitrogen (NO) by electrochemical cell. The NO cell is
optional and is NOT operator changeable.
In addition to the gas measurements the unit also displays:
- Lambda (λ) according to Brettschneider.
- Engine speed (rpm) via the ROTI module. An inductive rpm pickup, to be placed on a secondary ignition cable, is supplied as
standard equipment. A capacitive pick-up, for use on a primary or
injector wire, and a primary ECU/RPM adapter, for connection to
a square wave from the engine management system, are
available as options, thus making the analyser suitable for
conventional, wasted spark and direct ignition systems.
- Oil temperature via the ROTI module by means of an oil
temperature probe substituted for the oil dipstick.
Note:

3.2 Maintenance
Details of the maintenance operations that should be carried out by the
operator are included in this manual together with a list of operator
service messages and a list of maintenance parts.
All maintenance operations, other than those specifically described in
this manual, must be carried out by trained service personnel authorised
by the manufacturer.
In particular, full gas calibrations must only be performed by a qualified
representative of the manufacturer.

• To access the Gas Analyser Menu , select the “Gas Analyser” option
from The Diagnostic Platform Main Menu (see the SUN
Platform Operator’s Manual 5.1: ‘The Diagnostic Platform Main
Menu’).
The following options may be selected:
- Free Measurement Procedure.
- SUN EEC Test Procedure.
- The Gas Analyser System Setup Menu.
Note:
p If the DGA 2500 is configured to perform a country specific test
procedure, the SUN EEC test procedure will not be available. In this
case the “SUN EEC Test” button will be replaced by an icon button
corresponding to the country specific test in question.
• The “Free Measurement” procedure.
The Free Measurement procedure continuously measures and
displays the values for all available test parameters. Upper and lower
limits for any or all of these parameters may be introduced as
required. Refer to 8: ‘Operation – The Free Measurement
Procedure’for further information.

GAS ANALYSER MENU
The SUN EEC Procedure is based on the provisions of EU directives
which specify a procedure to be followed in testing motor vehicle
emissions and prescribes maximum default values for certain gas
emissions and related parameters. Refer to 9: ‘Operation – The SUN
EEC Test Procedure’.
• The “System Setup” option.
The The Gas Analyser System Menu allows operator maintenance
functions to be initiated, gas analyser system settings to be made,
gas analyser system information to be consulted and updates to the
gas analyser software to be loaded. Refer to 5.2: ‘The Gas Analyser
System Menu’ for further information.
• To return to the The Diagnostic Platform Main Menu, press the
“Home” icon button on the toolbar.
• To place the Gas Analyser in Standby Mode, press the “Standby” icon
button on the toolbar.
Once the Gas Analyser is switched on, it should remain on for the
whole working day, however, it is recommended that the unit should
be put into Standby Mode when tests are not being performed. This
will reduce waer and tear to the pump and increase the effecive life
of the filters.
The unit will return to the normal operating mode when:
- The “Standby” button is pressed once more, or
- One of the Gas Analyser Main Menu option buttons (“Free
Measurement”, “SUN EEC Test” “Country Specific Test”, or
“System Setup”) is pressed.
On leaving the Standby Mode, a Zero-calibration (see 6.2.4) and HC
Residue Check (see 6.4) will automatically be performed before the unit
returns to normal operation.
