6.3 732 IC Detector
IC Net 2.3 71
Range Measuring range in µ S/cm
Selection: 100, 200, 500 µ S/cm and
1, 2, 5, 10 mS/cm
Full scale The full scale range (operating range) sets
the desired sensitivity for the analog output.
The possible values of the full scale range
in
µ S/cm depend on the preset measuring
Range .
Ion Combination of polarity and temperature
coefficient:
Anion polarity = +, temperature coeff. = 2.5
Cation polarity = –, temperature coeff. = 1.5
Custom independent selection of polarity and tem-
perature coeff.
Polarity Polarity of the analog output signal:
+ positive polarity (e.g. for anions)
– negative polarity (e.g. for cations)
Temperature coeff. Converts automatically the conductivity
from the operating temperature of the
measuring cell to the reference temperature
of 20°C.
Selection:
1.5, 2.5 %/°C
Cell constant
Cell constant of the conductivity cell in /cm.
Entry range:
13 ... 21 /cm
Thermostat Operating temperature of the conductivity
cell within in the detector block.
Selection:
25, 30, 35, 40, 45 °C and off
Offset Offset of the zero point of the conductivity.
Selection:
0, 10, 50 %fs
Damping Electronic damping of the analog output
Selection:
on, off
<SET>
Send current parameters immediately to the
732 IC Detector. Parameters are not stored
in the system file (
*.smt ) as long as the file is
not saved.
For detailed information about the parameters of the 732 IC De-
tector see 732/733 Instructions for Use.
Time program
On the Program tab of the 732 IC Detector window a user-defined
time program for the remote output lines of the 732 IC Detector
can be entered. This program is started automatically as defined
in the
Start mode window (see section 4.4.3) either at the moment
the determination is started ( Start with determination ) or at the
moment the sample is injected (
Start with inject
).
