Bluetooth USB adapter

The Bluetooth USB adapter included in the scope
of delivery provides a radio link with BEA 060. It is
plugged into the PC/laptop. Readiness for operation
is indicated by the flashing LED (see operating manual
1 689 989 277).
!
It is not possible to operate any other item of Blue-
tooth hardware installed or plugged into the PC/
laptop, as this would interfere with data communica-
tion between the BEA 060 and the PC/laptop.

Microsoft Bluetooth driver

When the Microsoft Bluetooth driver is activated, the
Bluetooth manager symbol
and the Bluetooth device symbol
Bluetooth device symbol is not displayed if there is no
Bluetooth radio link.

Description of function

The BEA 060 is used to measure the exhaust gas com-
ponents CO, HC, CO , O
2 2
ted). The excess air factor (Lambda) is calculated on
the basis of the gas values measured.
The non-dispersive infrared method (NDIR – non-disper-
sive infrared spectroscopy) is employed for measuring
the CO, CO and HC quantities. The oxygen is deter-
2
mined using a sensor with electro-chemical action.
Warm-up time
The BEA 060 warm-up time is approx. 1 minute. Mea-
surements cannot be taken during this period.
Zero calibration at the start of exhaust emissions
tests
After switching on the pump, the zero point of the
analysis system is automatically calibrated (duration
30 seconds) with ambient air (zero gas).
Zero calibration during exhaust emissions tests
Following the start of an exhaust emissions test, the
BEA 060 automatically implements a system check with
ambient air at irregular intervals. To perform the system
check, the BEA 060 switches a solenoid valve to ambi-
ent air. The system is flushed with zero gas for 30 sec-
onds. An active carbon filter removes the hydrocarbons
from the ambient air drawn in.
Lambda air ratio measurement
The BEA 060 calculates the excess air factor (Lambda)
from the measured HC, CO, CO
tions.
Precise oxygen measurement is important for Lambda
calculation. Lambda calculation and oxygen measure-
ment must be activated for this purpose.
The Lambda value is calculated with the aid of the
Brettschneider formula:
