Criterion Selection dialog to indicate when the Measured values are applied during the
measurement.
￭ immediately
The displayed measured value will be immediately applied.
￭ time-dependent
The measured value will be applied during a Time interval that can be set.
For the PC/LIMS report, the individual measured values are grouped in a data
group.
The interval ends after the Stop time has been achieved.
The parameters are as follows:
– Time interval in seconds
Default value: 4 s / input range: 1 - 999,999 s
– Stop time in seconds
Default value: off / input range: 1 - 999,999 s
￭ when changed
The subsequent measured value will only be applied automatically if the devi-
ation from the previous measured value is greater than the value
delta pH/T/mV/Κ defined here.
– Delta pH
Default value: 0.50 pH / input range: 0.10 - 16.00 pH
– Delta T(pH)
Default value: 0.5 °C / input range: 0.1 - 100.0 °C
– Delta mV
Default value: 30.0 mV / input range: 0.1 - 999.9 mV
– Delta κ
Default value: 0.1 mS/cm / input range: 0.0001 - 10 mS/cm
– Delta T(κ)
Default value: 0.5 °C / input range: 0.1 - 100.0 °C
– Stop time
Default value: off / input range: 1 - 999,999 s
– Primary channel
Selection dialog for selecting the measuring channel that has to fulfill
the change criterion.
