and are shown alternately on the upper display line. Using the
Deg.C Adjust
keys, adjust the temperature reading (in 5 increments) to the first of the temperatures on
the pH/temperature curve.
and are shown alternately on the center display line. Using the
pH Adjust
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
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
5 points along the pH/temperature curve.
The analyzer calculates the pH/temperature relationship from the data entered.
