System Configuration; Measuring Parameters (Ph) - Ecolab MULTRONIC Notice Technique

9.3.1 System configuration page 1
3 comparisons: pH measurements on plug-in connection 1, 2 and 3 are compared.
Only the configurations and parameters for measuring module No 1 can be changed if a
multiple pH measurement has been activated. The same settings apply for the other modules
that contribute to the multiple pH measurement. These settings are automatically adopted.
Only the calibration can be carried out separately for every measuring module.
The adjustment of the measured value's maximum deviation from one another is specified in
the measuring parameters of the first pH measuring module.
9.3.2

Measuring parameters (pH)

Multiple pH measurement operating method
The pH values are constantly compared to one another and regulated through controller No 1
according to the measured values of the currently active measuring module (see above). In
the case of 3-comparisons, all three measured values are compared to one another, in the
case of 2-comparisons, only two measured values are compared to one another to ascertain
whether they are within the maximum deviation range.
If the measured value of a measuring chain deviates too much (> max. deviation) with regard
to the compared measured values, a corresponding alarm message, depending on the
measured values that are to be compared, is issued.
If three measured values are compared to one another and one value deviates too much from
the other two measured values the following alarm message is issued.

Settings
No comparison: every pH measurement
individually, no multiple pH measurement
2 comparisons: pH measurement on plug-in
connection 1 and 2 are compared.
Settings
Maximum deviation of 0.00pH to 2.00pH
Once the alarm message has been
acknowledged, the control is continued
through the two remaining measured values.
