10.2.3 Measurement settings
The following measurement settings are possible for conductivity mea-
suring cells:
Menu item Setting Description
Measuring
– Cell constant
– Calibrated cell constant Measuring cells whose cell constant
is determined by calibration in KCL
control standard (calibration ranges
see page 157).
The currently valid cell constant is
displayed in the status line.
– Adjustable cell constant... Any measuring cells with freely
adjustable cell constants in the range
0.250 to 25.000 cm
-1
.
– Adjustable LF 313T... Measuring cell LF313T(-ID), nominal
cell constant 0.100 cm
-1
.
The cell constant can be adjusted in
the range 0.090 to 0.110 cm
-1
.
– LF 213T Measuring cell with a nominal cell
constant of 0.010 cm
-1
.
The cell constant is permanently set.
– Temperature coefficient
– TC nLF Nonlinear temperature compensa-
tion
– TC Lin... 0.000 ... 3.000 %/K Coefficient of the linear temperature
compensation.
– TC off No temperature compensation.
– TC nLin1... ... TC nLin4... Measurement with entered or deter-
mined temperature coefficient.
