Table 6.2 Non-ABB and ABB Buffer Solution Temperature-corrected pH Values
6.2.3 Two-point pH Calibration (Automatic Mode)
An automatic pH calibration involves standardizing the instrument and electrode system using ABB supplied buffer solutions or
non-ABB buffer solutions of 4, 7, 9 and 10pH. Before starting pH calibration, check the Temp Comp setting in the Set Up
Parameters Page – see Section 7.3. Refer to Table 6.1 on Page 13 for an overview of the calibration procedure.
✶
Note. Pressing the key at any point during the calibration sequence prior to
the pH Check Value parameter aborts calibration and returns the display to the top
of the
Operating Page.
Advance to next parameter.
Calibration Access
Enter the required calibration code number, between 00000 and 19999. If an incorrect
value is entered, access to pH calibration is prevented and the display returns to the top
of the
pH Calibration Page.
Advance to next parameter.
Buffering Calibration Type
Select automatic buffering (Auto).
Advance to next parameter.
Buffer Type
Select ABB if using ABB buffering solutions, otherwise select Non-ABB.
The instrument is programmed to apply the temperature-corrected pH values shown in
Table 6.2 to the calibration calculation.
Buffer 1
Select the non-ABB 4, 7 or 9 pH buffering solution.
