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 5

C 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.
