Carrying out a manual calibration (ConCal)
Single-point calibration
Use any buffer solution for this rapid method.
The calibration will be the more exact the nearer the pH value of the
buffer solution is to that of the test sample.
Two-point calibration
Use two buffer solutions for this procedure:
z
first buffer solution: pH 7.0 ± 0.5
z
any other buffer solution
To carry out this procedure,
ConCal
has to be set as the buffer set (se
section 4.6.3) in the
Buffer
menu of the sensor menu.
Note
If single-point calibration was set in the menu, the calibration procedure
is automatically finished with the measurement of buffer solution 1 and
the calibration record is displayed.
1
In the measured value display, select the measured parameter
pH or mV with
<M>
.
2
Start the calibration with
<CAL>
.
The calibration display appears.
3
Thoroughly rinse the IDS pH sensor with distilled water.
4
Immerse the IDS pH sensor in buffer solution 1.
5
Start the measurement with
<MENU/ENTER>
.
The measured value is checked for stability (stability control).
The measured parameter flashes.
