If the measured conductivity value exceeds
±
180% of the set full-
scale range, the live display of
Conductivity
in the
WATCH WINDOW
changes it’s color to the settings for
Out of range
. (default: red). At the
same time the absolute conductivity is displayed instead of the auto-
zero value.
Method parameter
The
Method parameter
tab of the
819 IC Detector
window contains the
method startup values for the instrument. These values are sent and
applied to the 819 IC Detector by
Start determination
and
Startup hard-
ware
, or if the values are sent manually with

Range
Measuring range in
µ
S/cm
Selection:
100, 200, 500
µ
S/cm
and
1, 2, 5, 10
mS/cm
Select the measuring range so that the conduc-
tivity value of the eluent used is always within
the selected range. If the measured conductiv-
ity value exceeds the upper range limit by more
than 10%, the live display of
abs. Cond.
in the
WATCH WINDOW
changes it’s color to the set-
tings for
Out of range
. (default: red). The se-
lected measuring range limits the possible set-
tings of the full-scale range, which can be se-
lected to be maximum 2000 times more sensi-
tive than the measuring range.
