tiamo 2.4 (for Process Analysis)
Input range –2,000.0 - 2,000.0 mV
Default value 0.0 mV
c (blank)
c (blank) is the third characteristic of the calibration function U = f(log
c). It reflects to a certain extent the curvature of the calibration function at
the lowest concentrations. This curvature is caused by the influence of so-
called interfering ions. If the concentration calibration is carried out with
less than 3 standards, then c (blank) will be set equal to zero. The c
(blank) parameter is available for calculations as the variable 'Command
name.BLV'.

Specific calibration data for conductivity sensors
Cell constant
Cell constant of the conductivity sensor. This value can be determined
automatically with a calibration or entered manually. The cell constant is
available for calculations as the variable 'Command name.BLV'.
Input range 0.001 - 500 /cm
Default value 1 /cm

Shared calibration data
Calibration temperature
Temperature during the calibration. In addition, the display shows
whether the temperature was measured with a Pt1000 or an NTC temper-
ature sensor or entered manually (is not being displayed for the Thermop-
robe).
Input range –20.0 - 150.0 °C
Default value 25.0 °C
