Buffer sets for calibration

You can use the buffer sets quoted in the table for an automatic calibration. The
pH values are valid for the specified temperature values. The temperature
dependence of the pH values is taken into account during the calibration.
The buffer set is selected during calibration (see section 5.2.3
