Single and dual input analyzers for pH/Redox (ORP)
AX416, AX436, AX460, AX466 & AX468 4Setup
IM/AX4PH Rev. P 21
4.1.2 Set Up User Defined Buffers (pH Only)
Solution A: Enter point 1 (to 5)
Deg.C and Adjust are shown alternately on the upper display line. Using the and
keys, adjust the temperature reading (in 5 º 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 0.01 ph 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 ºC 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.
