are shown alternately on the upper display line. Using the
and
keys, adjust the temperature reading (in 5º increments) to the first of the
temperatures on the pH/temperature curve.
pH
and
Adjust
are shown alternately on the center display line. Using the
and
keys, adjust the pH reading (in 0.01pH increments) to the pH reading that
corresponds to the temperature reading entered above.
Notes.
1)
For accurate calibration, it is important to repeat the above for buffer solution A
at all 5 points along the pH/temperature curve.
2)
The displayed temperature value increases automatically by 5ºC from the value
set for the previous point. The setting may be increased but not decreased.
Solution B: Enter point 1 (to 5)
Solution B set up is identical to solution A set up.
Note.
For accurate calibration, it is important to repeat the above for buffer solution B at
all
5 points along the pH/temperature curve.
The analyzer calculates the pH/temperature relationship from the data entered.
