I.2.5.3. Connecting the tachometer
Connected to the cigar lighter plug
This is the simplest solution. It allows you measure the engine speed with no need to open the
vehicle hood. On some vehicles, however, the engine speed measurement may be less accurate
than with the unit connected directly to the battery, because of filters installed in the vehicle in
order to avoid interferences coming from the engine.
I.2.5.4. RPM measurement
Select RPM mode by pushing the rpm key.
Choose the RPM mode called Battery. After three seconds, it is required to select a cylinder
number. This number is corresponding to 4 stroke engine by default. If you want to measure a 2
stroke engine, see the picture below:
This counter is equipped with an automatic detection of cylinder number. In case of RPM loss,
when switching the device on, or when changing the number of cylinders, the counter will take a
few seconds looking for a stable RPM. When finally detected, the value can be seen on the gas
analyzer or opacimeter screen.

The remote can be used in several equipment by using channels A to D.
The remote control gives the possibility to use all the function shortcuts offered by the software
(F1, F2, … ←, ↑, … etc.).
1 –Selection:
- press F1 to launch the selection page in gas analysis mode.
- press F2 to launch the selection page in opacimeter mode.
- press F3 to launch the selection page in EOBD scantool mode.
2 –browsing:
Use the arrow keys to select the function desired. The active one is
blue lighted.
The up and down keys are used to switch from one active zone to the
other. The right and left ones, to change of zone.
When all the zones are correct, just press OK to save.

I.3. Installation, Commissioning
I.3.1.Advises
The device can remain switched on 24/24. Nevertheless, it is recommended to cut the power
supply during the night if the device is not used. When turning it on in the morning, getting
operational again can take the gas module a few minutes. As for the smoke head, it will take a
maximum of 9 minutes to reach the right operating temperature (preheating).
I.3.2.Commissioning
Before turning the device on, connect it to a 230VAC 50 Hz power supply
equipped with an earth plug and having been checked by an agreed technician.
Also check that the power cord is not damaged whatsoever.
The machine and smoke head power supplies are protected by filters
equipped with fuses. In case of replacement, use T2AL 250V fuses kind.
When working properly:
When the screen is turned on, the fan starts refreshing. The OS is downloaded.
The main menu will appear after a few seconds.
Use the direction arrows located either on the remote control or on the computer keyboard to
navigate through the menu. Click with the mouse or the OK key to save your choice. Press the ESC
key to go one page back at any time.
You can also use the touch screen to select your choice.
Main Menu: the equipment is ready for use

I.3.3.Navigation, user’s interface
The user’s interface has been designed for an optimal use of the touch screen. All the functions
are very accessible with a simple touch.
The touch function can also be replaced by the use of a remote control, giving access to the same
functionalities. Useful when tests are running remotely, from the inside of the vehicle for
instance.
A PC keyboard and a mouse can also be used for the navigation through the interface.
When necessary to dial information, a virtual keyboard will automatically appear.

I.4. Preventive maintenance, cautions
I.4.1.Overview
Every single device is checked before being shipped by a skilled technician who will stick on it the
primary check marks.
The seals, preventing anybody from influencing the metrological results quality, cannot be
removed excepted by an approved person. They guarantee the equipment conformity.
Electric Risks Caution: in case of gas analyzer or opacimeter opening, be careful to
electric risks of electrocution. Any manipulation should be done by a skilled person.
I.4.2.Cables and surfaces cleaning
Station, screen, keyboard, cell and cable can be cleaned with a clean rag and some alcohol. Do not
use any other product and especially solvents.
The screen should be cleaned with cotton. Do not use any abrasive product.

II. GAS ANALYZER
II.1. Principle
The gas analyzer is a module dedicated to PTI and automotive workshops. It allows measurement
of carbon monoxide (CO), carbon dioxide (CO2), hydrocarbons (HC) in hexane equivalent (C6H14),
and oxygen (O2) concentration of the gases from spark-ignition vehicles (petrol, high-octane
petrol, LPG), with or without catalytic converter. As an option, it can be equipped with the NOx kit
allowing nitrogen oxides to be measured.
The CAP3201 also allows the following values to be obtained at any time:
- Calculation of the corrected CO value
- Calculation of Lambda value
- The measurement of rotation speed (measured by induction clip, by battery input …)
- Measurement of oil temperature.
The measurement of CO, CO2and HC is carried out using non-diffusing infrared radiation.
The gas passes through a measuring chamber, at the ends of which there are three infrared
detectors and three transmitters. Each transmitter emits a specific wavelength associated with
one of the three gases.
Each of the detectors transmits an electrical signal corresponding to the received radiation
intensity.
Measurement of oxygen concentration is carried out by an active chemical sensor.

Principle of oxygen measurement:
The oxygen sensor is an electrochemical one; it is based on the principle of electrolysis. In the
presence of oxygen, an ionic current is generated through the cathode, the electrolyte and the
anode, giving rise to a potential difference at the terminals of a resistor, which varies according to
temperature. As a result, the sensor is temperature-compensated.

Principle of NDIR measurement:
The CAP3201 is based on non-dispersive infrared technology.
Instead of using a refractory prism to achieve the very high spectral definition of infrared light
(like those used in laboratory high performance equipment), the machine uses NDIR. NDIR devices
are generally used for measuring concentrations of a specific and limited set of gases in mixtures
having a known and limited collection of basic gases.
It is possible for example to take the measure of the CO2 concentration from a basic gas such as
the exhaust gas coming from a car. Some gases might have an absorption spectrum masking CO2
presence.
A specific collection of gases (CO2, C6H14, CO) is measured as follows: a unique range of
wavelengths in the infrared spectrum is selected for each gas in order to measure the point where
its absorption is high and where there is no other basic gas which is equally absorbent.
Optical filters transmitting only the given range of wavelengths are placed in front of the
thermocouple detector. When the set is full of gas, the infrared detector measures the reduction
in the infrared energy obtained for the range of wavelengths linked to each gas.
The signal processing electronics then determine the I/Io ratio.
I/Io = degree of absorption
I = signal received (sample) for each gas to be measured.
Io = signal for reference
