2.2 Calibrating gases (with manufacturer's certificate)
In order to save on calibrating-gas bottles, we recommend a
calibrating-gas bottle filled with mixed gases:
No. 4 5 % CO + 7.5 % CO
2
+ 2.000 ppm C
3
H
8
(propane)*,
accuracy of analysis ± 1%
In some countries (e.g. Germany), calibrating gases to OIML
Directive R99 A and B are used for calibration. In this case, gas
no. 4 can be dispensed with.
A 2000 ppm vol. C
3
H
8
(propane)*, accuracy of analysis ± 1%
3.5 % vol. CO, accuracy of analysis ± 1%
14 % vol. CO
2
, accuracy of analysis ± 1%
B 200 ppm vol. C
3
H
8
(propane)*, accuracy of analysis ± 2%
0.5 % vol. CO, accuracy of analysis ± 1%
6 % vol. CO
2
, accuracy of analysis ± 1%
* For practical reasons, the exhaust-gas analyzer module is
calibrated regularly with propane instead of hexane.
When the exhaust-gas analyzer module is calibrated in the
menu Readjustment with test gas in the Test functions
menu, the module is informed of the concentration of the
calibrating gas in ppm propane. The exhaust-gas analyzer
automatically takes account of the required "propane factor".

2. Testing equipment and settings for the
Service software
2.1 Testing equipment
z 1 laptop or PC
z P100
z P140
z Service software for BEA
z ESA module system software to test Engine test functions
z KTS module system software to test OBD functions
i The system software versions for Emissions System Analysis
and the KTS module must be installed on your laptop or PC,
otherwise the Service software will not be fully functional!
z BEA - PC or laptop, COM1 connecting lead.
As an alternative to the lead shown, the connecting lead for
the data terminal (DTL) 1 684 465 320, can be used.
z Adaptor cable AL350 to check OBD connecting line to
control device.
z Test connector KS350 to check OBD interface in BEA
z 1 flow meter (rotameter), measuring range 1.5 to 2 l/min or
10 l/min, test medium air, 20 °C, 1 bar absolute
z 1 absolute-pressure gauge (barometer) or adjusting barometer
set to absolute pressure. Measuring accuracy 5 hPa (5 mbar)
z 1 gas wash bottle (pearl bottle)
z 1 digital multimeter (DMM)
z 1 DC calibrator, 0 to 15 mV
z 1 stabilizer DC U = 0Volts - 30Volts
z Viton hose for calibrating-gas connection (do not use hoses
of different material)
z 1 U-tube, water gauge 100 cm, inside diameter max. 8 mm
z Compressed air for cleaning exhaust-sample probe and hose
z Torque screwdriver 0.2 - 4 Nm
Insert for inner TORX screws size T15
