Checking/Calibrating with Test Gas
For the standard design of the LS2 Lambda Probe, a special testing device is required (type
650R1015).
WARNING!
Danger of burns!
If the probe is operated when removed, there is a danger of burns on the
probe housing.
Never lay the probe on flammable material and heat it up.
Wear protective gloves
Description of the Testing Device
General Information:
The probe signals are pressure-dependent so they must be tested in a pressure-free environ-
ment. The testing device takes this into consideration and guarantees the best results in spe-
cific ranges. In exceptional cases, the pressure of the testing device must be adjusted to the
pressure of the measuring point through an additional device.
Choose a test gas combination so that O
2
content lies in the usual plant specific range and
within the specified measuring range of the probe.
Description:
The testing device is a device for the task of testing gases via the test gas connection ON (Nr.
4 in
Fig. 5-2 Testing device laying on the table
) onto the probes LS2 in the standard housing.
The probe can be tested or calibrated by means of test gas function.
The testing device can used lying on the table or plugged into the flue gas channel (

For gas-tight fixing at the flue gas channel, the probe screw joints (clamping ring/screw cap)
can be attached to the plug in nozzle for flue gas channel.
