8. Selecting Buffers for Auto Buffer Recognition
The
Aqua-DP
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. Release the
key when the message, “
Buffer 1 Select
” is
displayed.
4. The display will now show the currently selected primary buffer, for
example…
7.00pH
Select
or
6.86pH
Select
5. Use the
or
keys to alternate between pH7.00 and pH6.86
buffers.
6. Press the
key to save the primary buffer.
7.
After the message, “
Buffer 2 Select
”, the display will now show the
currently selected secondary pH buffers, for example…
4.01/9.18pH
Select
or
4.01/10.0pH
Select
8. Use the
or
keys to alternate between pH9.18 and pH10.01
buffers (the display shows pH10.0 for the latter but this buffer is
stored as pH10.01).
9. Press the
key to save the secondary pH buffers.
10. The buffer recognition setting is kept in memory when the meter is
switched off, even if the battery is removed.
