12 Calibrating a pH measuring chain

Entry of the pH-value of the buffer solution
•
without buffer recognition:
Check whether the "pH buffer 1" matches the pH-value of the
buffer solution used. If a buffer set table was not specified, the
"buffer 1 pH" value is taken from the calibration default settings.
It is still possible to change this manually here.

•
with buffer recognition:
A prerequisite here is that a buffer set table has been selected
in the buffer set table and the pH-value of the buffer solution
used is contained in this buffer set table. If these prerequisites
are satisfied, the pH value of the buffer solution is determined
automatically during the calibration.
5
Wait until the measured value displayed stabilizes and then con-
firm the result of the measurement by pressing "OK".
6
For each additional calibration point, repeat steps 3 to 5 with the
required buffer solutions.
7
A protocol summarizing the calibration values determined then ap-
pears. Acknowledge the protocol by pressing "OK".
Failed calibrations are canceled at this point and discarded.
8
Press "Yes" to accept the Calibration values determined and enter
the Calibration in the Calibration logbook.
Press "No" to discard the results.
