4.2.5 Selecting the measuring range, AutoRange

You can use the DurOx 325 or CellOx 325 sensors. If the automatic
recognition function recognizes the DurOx 325 sensor, the measure-
ment is carried out at a lower resolution. The CellOx 325 sensor mea-
sures with a resolution that is a factor of 10 higher.
Each of the measuring parameters has 2 measuring ranges available.
AutoRange causes the measuring instrument to change to measuring
range II if measuring range I is exceeded, and also vice versa.
To switch the automatic measurement range selection on/off, see sec-
tion 4.6 C
