4.2.4 Calibrating with
CAL CON 1P
Display indications during 1-point calibration with
CAL CON 1P
* 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 the mea-
sured value is stable, the next
display indication appears.
* Enter the pH value of the second
buffer solution.
Confirm with <OK> .
Enter the nominal pH value of
the second buffer solution
according to the displayed tem-
perature with
<  > and
confirm with <OK> .
Successfully calibrated.
End of the CAL_CON_2P calibra-
tion.
The values determined for
Slope
and
Asymmetry potential
are dis-
played.
Calibration is finished.
Confirm with
<OK> .
The display returns to the mea-
sured value display.
Display Explanation
* Have any buffer solution ready.
For this you can use any one buf-
fer solution if its pH value at the
current temperature is known.
The calibration will be the more
exact the nearer the pH value of
the buffer solution is to that of the
test sample.
* Rinse the sensor.
* Immerse the sensor in the buffer
solution.
* Wait for a stable measured
value.
Follow the instructions on the
display. As soon as the mea-
sured value is stable, the next
display indication appears.
* Enter the pH value of the buffer
solution.
Confirm with <OK> .
Enter the nominal pH value of
the buffer solution according to
the displayed temperature with
<

> and confirm with
<OK> .
