1 Introduction
Thank you for purchasing the smoke meter TEN EDA 2.The EDA2 smoke head is developed and produced by TEN
Automotive.
Due to the smart design, the EDA 2 offers you a wide range of possibilities for measuring the smoke emissions of
diesel passenger and commercial vehicles.
The new model smoke head is compact and provided with the latest microcontroller controlled electronics. The
smoke chamber is completely made of aluminum and uses the so called unique ‘natural flow’ system that
guarantees a minimum of maintenance.
In this user manual we describe the combination of the EDA2 smoke head and the INNOVA500 . The INNOVA 500
has digital LED displays and a thermal printer to provide you all necessary information during a emission test.
Before using the EDA 2, it’s absolutely necessary to read this user manual carefully !
If you have any questions about the EDA 2, please don’t hesitate to us :

2 Preparations
RPM
The RPM of the vehicle is recorded by a optional piëzo clamp or RPM adapter. The standard piëzo clamp has a
diameter of 6 mm and suitable for most European vehicles. Dismount the engine cover plates of the vehicles.
- Find a location were injection pipe is straight.
-Take care take this piece of pipe is clean and dry.
- If necessary, use sand paper to clean the injection pipe.
- Mount the piëzo clamp around the injection pipe.
- Tighten the knob of the clamp but don’t overdo.
- Place the black crocodile clamp (ground) at the injection pipe near the piëzo.
Check that the RPM is recorded correctly. If not, repeat the procedure mentioned above at a different location of the
injection pipe.
Figure 2. Placing the piëzo clamp
Remark: the piëzo clamp can not be used for all types of diesel vehicles, for example common rail diesels. Here for
you need a special RPM adapter. If you use an adapter, always follow the instructions given by the manufacturer.
Oil temperature sensor
Take care that the length of the sensor is not longer than the length of the dip stick. Move the adaptation rubber
until the length of the sensor is correct. Now place the temperature sensor in the dip stick holder of the engine.
Figure 2. The oil temperature sensor
After testing you have to remove the temperature sensor from the engine. Clean wasted oil from the engine and
temperature sensor with a clean towel. Don’t forget to place back the dip stick !

Sample probe
Always use the correct sample probe. Probe 1 has a diameter of 10 mm and is used for exhausts with a diameter
smaller than 70 mm. Probe 2 has a diameter of 27 mm and used for exhausts with a diameter equal or larger than
70 mm.
Place the probe a far as possible in the exhaust. Take care the gas flow in probe is correct. Avoid sharps curves or
bending .
Figure 3. Placing the sample probe.
The temperature of the sample probe can rise up to 200 ºC during a smoke test. Always wear protection
gloves while you are touching the exhaust or sample probe.
During a zero calibration of the smoke meter, the sample probe must be removed from exhaust or the
engine must be switched off!

3 Smoke test
From standby mode you press the function key and select the menu item ‘DIESEL’ with the up or down keys.
Confirm your selection with the enter key. Now the following screen will appear.
Figure 4. Smoke test
This screen will only appear if the smoke cell temperature is over 80 ºC. If the temperature is lower than 80 ºC the
INNOVA 500 will display the message ‘EDA heating’ and only the cell temperature is displayed.
If the opacity and max.opacity display shows the message ‘----‘, you need to perform a zero calibration. Press the
zero calibration key to activate a zero calibration.

Important!
We advise you to perform a zero calibration regularly. Take care that during a zero calibration the sample is
removed from the exhaust of the vehicle.
Printing
If you wish to print the actual values of the smoke meter, you can press the print key. The thermal printer of the
INNOVA 500 prints all relevant information including the date, time etc at a piece of thermal paper.
Warning: thermal paper has a restricted lifetime. Don’t store thermal paper near ‘hot’ sources.

always use mode B.
PROBE Select sample probe 1 or 2.
Probe 1 = Ø 10 mm, exhaust diameter < 70 mm (passenger cars).
Probe 2 = Ø 27 mm, exhaust diameter >= 70 mm (large commercial vehicles).
DIVISION Here you can set the division ratio for the RPM, for example 1,2,3,4 etc.
DISPLAY Select what you want to display at the display at the right bottom, RPM or oil temperature.
STATUS Menu to check the status of the EDA2 smoke head.
VERSION Software version of the smoke head EDA2, for example 9.01
TEN
Test Equipment Nederland B.V. (C) Version 3.0 February 2008 Pagina 8
CS_A CS_B The corresponding checksum of the software.
SERIAL The serial number of the smoke head.
CURR.DATE Current date.
CAL.DUE Calibration due date.
CNT. Calibration counter. After each calibration this counter automatically increments.
FILTER Dynamic test to check the low-pass filter-time constant. First a zero calibration is performed. After
this the EDA 2 checks the rise time from 0 till 90% opacity. Than the EDA displays ‘time 1.00’. This
value must be between 0,95 and 1,05 seconds. Normally the time is 1,00 seconds.
During this test the sample probe must be removed from the exhaust. Don’t influence the smoke
meter in any way!
Remark: the ‘STATUS’ menu is only used for checking purposes.
4 Official test
During the smoke test just press the Enter key to start the official test. The official test is a series of 3 free
accelerations to measure the maximum emission of a diesel vehicle.
First the EDA 2 performs a zero calibration. Be sure that during a zero calibration the sample is removed from the
exhaust tail pipe. After the zero calibration you insert the probe in exhaust of the vehicle.
Then the oil temperature is measured. The EDA 2 waits until a temperature of 60 ºC is reached. As soon as the
engine temperature reaches 60 ºC, the EDA automatically continues. If the temperature of 60 ºC is not reached or
you just want to continue, press the Enter key. Now the INNOVA 500 will proceed with the next program part.
After measuring the temperature the operator must be prepared to perform the free accelerations
Between each acceleration the operator can see a down counter of 6 seconds. During the count down the throttle of
the vehicle is not touched.
After the count down the INNOVA shows ‘THROTTLE UP’ which means that the operator has to press the pedal
completely until the maximum engine speed is reached. Maintain this situation for maximum 2 seconds. Then
release the pedal and let the engine speed come back to idle. The SMOKE METER light blinks.
After 4 seconds the INNOVA 500 shows ‘RELEASE THROTTLE’. These 4 seconds are the maximum throttle up
time for vehicle with a ‘slow’ engine (large commercial vehicles). For passenger cars just maintain the maximum
engine speed for 2 seconds !
After each acceleration the EDA 2 displays the result of the test for 3 seconds. After this the INNOVA 500 starts a
new count down for the next acceleration.
After completing the official test, the EDA 2 shows the result of the test, the calculated average of the opacity of the
3 free accelerations, at the opacity display. If the result is out of limits, more than 50%, the display blinks.

EDA2 No communication between the IINOVA 500 and EDA2 smoke head. Check the communication
OFF-LINE cable connection. Check that the EDA2 is switched on.
EDA2 The smoke cell temperature is below 80 ºC. The smoke cell is heating up.
HEATING
ERROR This message can occur during a zero calibration. Reason for the error can be:
a) Receiver needs to be cleaned, see Chapter 12.
b) The halogen light source is defect, see Chapter 12.
c) The smoke head is located in a location with to much direct sun light.
Move the smoke head to another location.
6 Maintenance
Cleaning
Clean the outside of the INNOVA 500 and smoke head with a soft towel and eventually with a non aggressive liquid
like Glassex. Before cleaning the unit always switch off the INNOVA 500 and remove the mains plug. Let the smoke
head cool down till ambient temperature.
Replacing the printer paper
Open the printer by pulling the lit at the cover forwards. Remove the old roll and place the new roll in the printer. Let
a piece of paper of approximately 10 cm hang out of the printer. Press with both hands at the printer cover to close
the printer. Press a the paper feed key to check the paper transport.
Replacing the fuses
Before you change the fuses always switch off the INNOVA 500, remove the power lead and let the smoke head
cool down until ambient temperature. Open the little lit of the main switch at the rear of the EDA, no. 12 of figure 2.
Take out the fuses and place the new fuses in the holders of the lit. Use 230 V 2AT fuses. Close the lit.
In the smoke head the fuse holder is located at the bottom of the EDA 2, no. 5 of figure 3. Press and open the
holder by turning it counter clockwise. Take of the holder with the fuse. Replace the fuses. Use 230 V 2AT fuses.
Close the fuse holder by pressing it and turning it clockwise. If you have to change the fuses frequently, please
contact our service department!
Calibration
The EDA 500 must be calibrated once every 12 month. The calibration can only be performed by authorized
technicians from your supplier. We advise you to take a service contract including the annual calibration.
Cleaning the optical components of the smoke head
If the receiver gets polluted, the receiver voltage will go down and the smoke meter will show ‘ERROR’ during a
zero calibration at the displays. Switch off the INNOVA 500 and let the smoke head cool down until ambient
temperature. Loosen the right mounting ring of the smoke chamber and take out the cone. Now take the receiver
support out of the cone. Clean the front surface of the receiver with a clean and soft cotton towel. Don’t touch this
surface, the lens, with your fingers. Put the support back to its position and place cone into the smoke chamber.
Tighten the mounting ring. Switch on the smoke meter and perform a zero calibration. Check that the smoke meter
is not showing the error message again.
