Analog input – conductivity and TDS measurement
Select the symbol IN/OUT in the main menu and then the symbol
ANALOG.
Measure
To select the parameter conductivity or TDS. TDS is the abbreviation
for total dissolved solids and is consisten with the residual after
complete water evaporation.
Measuring range
IL
0-2.000/20.00/200.0/2000 mS/cm
CM
0-20.00 mOhm/0-2.000/20.00/200.0µS/cm (c=0.05)
0-2000 µS/cm bzw. 0-2.000mS/cm (c=0.2)
0-20.00 mS/cm (c=1)
0-200.0 mS/cm (c=10)
Averaging
To activate the averaging function, select:
˃
OFF: no averaging
˃
low: mean of 5 values
˃
medium: mean of 10 values
˃
high: mean of 20 values
Cell constant
The cell constant takes account of the sensor geometry and allows to standarzise the measurment.
You adjust the cell constant via menu or calibration.
