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 components. The oxygen is deter-

mined using a sensor with electro-chemical action.
Warm-up time
The BEA 060 warm-up time is approx. 1 minute.
Measurements cannot be taken during this period.

Zero calibration at the start of exhaust gas
measurement
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 gas measurement
Following the start of exhaust gas measurement, the
BEA 060 automatically implements a system check with
ambient air at irregular intervals (the oxygen measure-
ment drift is monitored and re-adjusted if necessary).
To perform the system check, the BEA 060 switches
a solenoid valve to ambient air. The system is flushed
with zero gas for 30 seconds. An activated charcoal
filter removes the hydrocarbons from the ambient air
drawn in.
Excess air factor 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:
