not selected. The bottom part of the display shows the pH
value and the range of the highlighted buffer.
4 Use the arrow keys to highlight the target buffer, then
press [Setup] to select or deselect it.
For example, to select the 4.008 pH buffer, use the arrow
keys to highlight the icon with 4.008 pH. Press [Setup] and
this icon is selected.
To prevent selecting buffers with overlapping pH ranges,
select only buffers necessary for measurement and clear
selection of other buffers.
The meter allows selection of up to five buffers for each
Buffer Group Setup.
Before each measurement, Agilent recommends recalibrating
the electrode. Calibration overwrites the previous calibration
data.
Recalibrate the electrode regularly. To set a calibration
reminder, see "To set up the system (System Setup)"
page 29.
To perform the calibration:
1 If not connected, connect the electrode to the meter. Store
the short- circuit plug in a clean, dry place.
2 View that the desired buffers have been set up in the
desired buffer group.
3 The display for pH calibration is shown in
page 37. The upper area shows the current pH, potential
and temperature value (in this example the slope is set to
100.00%). The bottom area shows the current calibration
data (if any).
