17. Selecting Buffers for Auto Buffer Recognition
The
WP-81
is factory set to automatically recognise pH4.01, pH7.00 and
pH9.18 buffers. However, some users may prefer to use pH6.86 instead
of pH7.00 and pH10.01 instead of pH9.18. The following procedure
describes how to set which of these buffers are automatically recognised
at calibration.
1. Switch the meter
OFF
.
2. Press
and HOLD
the
key while switching the meter back on.
3. The buffer selection menu is now displayed.
Select >F1:7.00pH
Buffer F2:6.86pH
The arrow indicates the current selection.
4. Press
to select pH7.00 as the primary buffer.
Press
to select pH6.86 as the primary buffer.
Press
to quit buffer selection and retain the current setting.
5. The display will now show the currently selected high pH buffer.
Select >F1:9.18pH
Buffer F2:10.0pH
The arrow indicates the current selection.
6. Press
to select pH9.18 as the high pH buffer.
Press
to select pH10.01 as the high pH buffer (the display shows
10.0 for the latter, but this buffer is stored as pH10.01).
Press
to quit buffer selection and retain the current setting.
7. The setting is kept in memory when the meter is switched off, even if
the battery is removed.
