4.2.3 Calibration with CAL CON 2P
Messages displayed during two-point calibration with CAL CON 2P
Display Explanation
* Have buffer pH 7.0 ± 0.5 and
any second buffer solution ready. You can use two buffer solutions
of which the pH values according
to the actual temperature are
known:
– first buffer solution
pH 7,0 ± 0,5
– second buffer solution with
any pH value
* Rinse the sensor.
* Immerse the sensor in the first
buffer solution pH 7.0 ± 0.5.
* Wait for a stable measured
value. Follow the instructions on the
display. As soon as a stable
measured value is reached, the
next display appears.
* Enter the pH value of the first
buffer solution. Select the pH value of the first
buffer solution according to the
displayed temperature with
d
and confirm with
g
.
* Rinse the sensor.
* Immerse the sensor in the sec-
ond buffer solution.
* Wait for a stable measured
value. Follow the instructions on the
display. As soon as a stable
measured value is reached, the
next display appears.
* Enter the pH value of the sec-
ond buffer solution. Select the pH value of the second
buffer solution according to the
displayed temperature with
d
and confirm with
g
.
