13 Calibrating a pH measuring chain
4 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 calibration default settings and the pH-value of the Buffer
solution used is contained in this Buffer set table. If these pre-
requisites are satisfied, the pH value of the Buffer solution is de-
termined automatically during the calibration.
5 Wait until the measuring 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 re-
quired 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.
