-U1- Specifiable Buffer Set You can specify a buffer set with 2 buffer solutions in the temperature range of 0 ... 95 °C, step width: 5 °C. To do so, select buffer set -U1- in the configuration menu. As delivered, the Ingold technical buffer solutions pH 4.01 / 7.00 are stored as buffer set and can be edited. Conditions for the specifiable buffer set: • All values must lie in the range pH 0 ... 14 • Maximum difference between two adjacent pH values (5 °C step width) of the same buffer solution: pH 0.25 • The values of buffer solution 1 must be lower than those of buffer solution 2: The difference between values for identical temperatures must be greater than 2 pH units. Faulty entries are indicated in measuring mode by the “FAIL BUFFERSET -U1-“ message. The 25 °C value is always used for buffer display during calibration. 143
