Menu Items and Options
Sample ID
Set the sample ID to associate reading with the data log.
0000 to 9999
Default 0000
Cell Constant
Set the cell constant to match connected electrode.
2-pole electrode (K=
0.1)
2-pole electrode (K=1)
Default
2-pole electrode (K=10)
4-pole electrode
Calibration Points
Set the number of calibration points.
1 to 3 points
Default 3 points
Temperature Coefficient
Set the temperature compensation type and coefficient.
The linear temperature compensation is appropriate for most samples.
If the current samples are belong to the natural water, using the non-
linear compensation is necessary. Note, non-linear compensation can
only be performed at temperature from 0 to 36° C. If the temperature
reading is out of above range, the meter will show a warning.
Linear (setting range: 0.0 to 10.0%/° C)
Default 2.1%/° C
Non-linear
Pure Water Coefficient
The pure water coefficient is used to correct the sample solution with
a conductivity of less than 5 µ S/cm. If enabled, the meter will be
automatically calculated and applied coefficient for ultra-pure water
measurement.
