If the calibration fails again, the hydrogen sensor has to replaced
by a new one.
4 Unscrew and remove the thread-
3.1.5
ed sleeve [A].
5 Remove the hydrogen sensor [B]
from the flow cell.
6 Dry the sensor membrane and the
3.1.5
flow cell with a soft paper tissue.
7 Flush the flow cell with hydrogen.

the saturation current should be about
xx.x%
2.0 A to 4.5 A. If the measuring val-

ues are not stable during the measur-
ing period, the calibration will be
discarded.
If this is the case, check and if neces-
