Checking/Calibrating with Test Gas

WARNING!

Danger of burns!

Probe becomes hot during operation.
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

or COe content lies in the usual plant specific range

and within the specified measuring range of the probe. In standard applications in the com-
bustion technology, O

2

concentration lies at 2-5 vol.% and CO

e

concentration lies between

100

...

500 ppm. The following indicated test gas composition guarantees best results.

Description:

The testing device is a device for the task of testing gases on the probes LS1/KS1/KS1D in
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.
