Setting sensor protection:
For devices with the "Dilute all sensors" option: If a measuring cell threshold value is
exceeded in slot 2, the gas to sensor 2 is diluted by factor five. If a measuring cell
threshold value is exceeded in slot 3, gas to all sensors is diluted by factor two.
With dilution active, the reading resolution and accuracies will change, see Technical
data. Diluted values are represented inversely.
If the threshold is still exceeded despite dilution, the instrument is switched off. To de-
activate sensor protection, set the thresholds to 0 ppm.

Deflt
To extend the measuring range and
protect the measuring cells against over-
loads, you can set thresholds which, when
exceeded, activate sensor protection.
Thresholds for a variety of parameters can
be set, depending on the measuring cells
that are connected.
For instruments without "Dilution of all sen-
sors" option: If a threshold of the measur-
ing cell in slot 2 is exceeded, the gas to
sensor 2 is diluted by a factor of five.
There is switch-off if a measuring cell
threshold value is exceeded in slot 3.
