8 Calibrating a pH measurement chain
✱
Start the two-point calibration with the
key.
✱
With manual temperature entry, use the
and
keys to set the
calibration solution temperature and confirm your entry with the
key.
✱
Wait until the display value has stabilized; then press
to continue.
✱
Set the displayed value to the value of the first buffer solution with the
and
keys; then press
to continue.
✱
Rinse and dry the pH combination electrode.
✱
Immerse the pH combination electrode in the second buffer solution.
✱
Wait until the display value has stabilized; then press
to continue.

Now the source of temperature acquisition can be selected (manually, or using
the temperature input of the basic board, or the temperature input via the
optional board). This source will be active for the duration of the calibration.
An example follows: Manual temperature entry:
