Test probe
1. Install probe:
Push probe into the testing device until stop.
2. Heat up probe:
A cold probe has to be heated up for at least 45 minutes in the installed condition. Should
an already heated up probe be installed in the testing device, then wait for 15 minutes.
CAUTION!
The testing device with plugged in heated probe would get hot.
Risk of burning!
3. Test gas function:
The test gas connection would be connected to the pressure reducer or the compressed
air supply of the test gas bottle using hose or hose clamp (D
i
=4; D
a
=6 mm (0.236" in)). The
corresponding test gas is to be given up with 2  1 bar (pressure behind the bottle pressure
reducer). After 2 minutes, the probe calibration and testing can take place.
NOTICE
For test gas usage of 2 bar, test gas pressure lies at 1.6 l/min and increases at 0.6 l/min per
bar increase in pressure.
The procedure for offset and O2 adjustment are described in chapters 5.1.8.1 Offset Calibra-
tion perform to 21 % O

and 5.1.8.2 O

Calibrating in the Operating Point with Reference
Measurement.
NOTICE
With LS2-HT, the test gas to be tested/calibrated can be connected directly at the hose con-
nection for calibration gas, this can be done while combustion is running, the probe does not
have to be removed. A special testing device is not necessary. The required test gas quantity
lies between 40 ... 60 l/h, if no flow meter is available, a test gas pressure of 5-10mbar can be
set.
Probe calibrated
4. Calibration/probe testing:
According to table 4, LS2 is to be tested within 2 steps while.
Testing/
calibration
Description
1 Offset Offset testing/calibration
Compare oxygen values of probe and test gas A.
Should the deviation of oxygen value be less than or equal to 0.2 vol.% of
21 vol.% (as shown in parameter 15, internal value O
2
), the probe is fine.
Should the deviation of oxygen value be more than 0.2 vol.%, the probe
must be calibrated according to the manual.

testing/calibration
Compare oxygen values of probe and test gas B.
Should the deviation of oxygen value be less than or equal to 0.1 vol.% of 3
vol.%, the probe is fine.
Should the deviation of oxygen value be more than 0.1 vol.%, the probe
must be calibrated according to the manual.
