tiamo 2.4 (for Process Analysis)
Input range –2.147E+9 - 2.147E+9 mV
Default value 2,000.0 mV
Cell constant monitoring (for conductivity sensors only)
on | off (Default value: off)
If this option is activated, then a check will be made to see whether the
value determined during the determination of the Cell constant of a
conductivity sensor is within the defined limit values. If it is outside them,
a corresponding message appears and you can select whether you will
nevertheless accept the value or whether the previous value is to be
retained.
Lower limit
Lower limit value for cell constant.
Input range 0.001 - 500 /cm
Default value 0.001 /cm
Upper limit
Upper limit value for cell constant.
Input range 0.001 - 500 /cm
Default value 500 /cm

NOTE
This tab only appears for pH and ISE electrodes.
History table
The table contains the last 10 calibrations for the selected sensor and can-
not be edited or sorted. The individual calibrations are sorted according to
date in such a way that the most recent determination is listed last. For pH
electrodes, the Slope and the pH(0) are displayed, for ISE electrodes the
Slope, E(0) and c (blank), and for conductivity sensors the Cell con-
stant.
Slope, pH(0), E(0), c (blank), Cell constant
The values are shown in the following colors:
￭ Blue, if the values have been determined automatically by a method.
￭ Black, if the values have been entered manually.
￭ Orange, if the values are outside the warning limits.
