4.5 Measurement parameters
4.5.1 key
PARAM
The key combines the most important parameter settings
for the 732 IC Detector. The parameter values entered here are
available for the measurement immediately following their confirmation.
They can be stored and recalled together with the current existing
program as a method. The key opens the following main menu:
PARAM
>PARAM/detector Settings for the conductivity detector
PARAM
>PARAM/analog output Settings for analog output
PARAM
>PARAM/plot Settings for graphics plot
PARAM
>PARAM/709 IC Pump Settings for 709 IC Pump
Repeated pressing of the key selects the submenus in turn.
The individual inquiries are accessed using the key and ex-
ited with the key. The following listings show all dialog items
appearing under . The values shown in the displays are
default values, possible entry values or ranges are shown below the
display.

range: 1.00 mS/cm
100, 200, 500 µ S/cm
1, 2, 5, 10 mS/cm
Measuring range
7 stages from 0
… 100 µ S/cm to 0 … 10 mS/cm are
available for the measuring range. Select the measuring
range so that the conductivity value of the eluent used
is always within the selected range.
If the measured conductivity value exceeds the upper
range limit by more than 10%, " -------- " appears in
display 11 instead of a measured value. In such a case,
set the next higher range.
The selected measuring range limits the possible set-
tings of the full-scale range, which can be selected to
be maximum 2000 times more sensitive than the meas-
uring range.
If the measuring range is changed, the auto-zero
function is automatically switched off.
