Medium temperature compensation
Tables for Medium 1...3:
For medium temperature compensation, tables can be created in the CPM 153 for three
different media. Before starting the process, the most suitable table for the active
medium can be selected.
Procedure:
•
Take a sample from the process. The pH value should be as near as possible to the
set point of the process.
•
In the laboratory, heat the sample to
at least
the process temperature.
•
During cooling, record the value pairs for pH and temperature at those temperatures
at which you later wish to take measurements (e.g. process temperature and ambient
temperature in the laboratory).
•
Enter these recorded value pairs in the table (Field GBB3). As a reference
temperature (Field GBC1) select the temperature, at which the set point of the process
is defined (e.g. ambient temperature in the laboratory).

Medium compensation
Selection for temperature compensation
Temperature = Automatic (ATC) or manual (MTC)
temperature compensation.
Medium compensation (only for pH) = Compensation
of the medium temperature using customer-specific
tables (see below).

Temperature:
GAA1 ATC K1
MTC
MTC+Temp.
Select temperature compensation
ATC = automatic temperature compensation with a
temp. sensor circuit 1
MTC = manual temp. comp. (with fixed temperature,
specified in Field GAA2)
MTC+Temp. = as MTC. On the display however, the
value which appears is what the temperature sensor
measures in the medium.

temperature calibration
The value current measured by the temperature sensor
can be changed/adapted. The temperature difference
is stored internally as an offset value.
