4.2.3 Calibrating with
CAL CON 2P
Display indications during 2-point calibration with
CAL CON 2P
* Rinse the sensor.
* Immerse the sensor in the first
buffer solution.
* Wait for a stable measured
value.
Follow the instructions on the dis-
play. As soon as the measured
value is stable, the next display
indication appears.
* Rinse the sensor.
* Immerse the sensor in the sec-
ond buffer solution.
* Wait for a stable measured
value.
Follow the instructions on the dis-
play. As soon as the measured
value is stable, the next display
indication appears.
Successfully calibrated.
End of the CAL_TEC_AUTO cal-
ibration.
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 buffer pH 7,0 ± 0,5 and any
second buffer solution ready.
For this calibration procedure,
use two buffer solutions whose
pH value at the current tempera-
ture is known:
– First buffer solution
pH 7.0 ± 0.5
– Second buffer solution: arbi-
trary
* 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 the mea-
sured value is stable, the next
display indication appears.
* Enter the pH value of the first
buffer solution.
Confirm with <OK> .
Enter the nominal pH value of
the first buffer solution according
to the displayed temperature
with
<

> and confirm with
<OK> .
