Stratos®Pro A4... PH User Manual

-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.
