Each of the calibration points has its own range of pH buffers values to enter.
This limitation enables automatic detection of the buffer solutions by the
meter. Table 1 contains the manufacturer’s settings of the pH buffer solutions
values used for calibration. They can be changed according to the ranges
given in this table. The range for each of the calibration points is wide, what
enables to use buffer solutions with values differing from those set by the
manufacturer even to a large extent. In every case the introduced buffer
solution will be automatically detected by the meter. There is a possibility to
introduce values of buffer solutions with two or three decimal places,
depending on the chosen resolution.
