are suitable, e.g.
4310
.
IDS conductivity sensors with other cell constants are unsuitable for this simple
calibration procedure. As an alternative, you can manually determine the cell
constant and adjust it in the menu (see section 8.3.5 S
You can determine the actual cell constant of the IDS conductivity sensor within
a valid range (e.g.
4310
: 0.450 ... 0.500 cm
-1
).
The cell constant is determined in the check- and calibration standard 0.01 mol/
l KCl (1413 µS/cm @ 25 °C).
In the default condition, the calibrated cell constant is set to the nominal cell
constant of the IDS sensor (e.g.
4310
: 0.475 cm
-1
).
For this calibration procedure, the
Type
setting must be set to
cal
. Proceed as
follows to determine the cell constant:
1.
Connect the conductivity sensor to the meter.
2.
In the measured value display, select the conductivity parameter with
<M>
.
3.
Start the calibration with
<CAL>
.
The cell constant that was calibrated last is displayed.
4.
Immerse the conductivity sensor in the check- and calibration standard
0.01 mol/l KCl (1413 µS/cm @ 25 °C).
5.
Start the measurement with
<ENTER>
.
The measured value is checked for stability (stability control).
The [AR] status indicator is displayed. The measured parameter flashes.
6.
Wait for the end of the measurement with stability control (beep,
[HOLD][AR] status indicator) or take over the calibrated value with
<ENTER>
.
The calibration record is displayed and output to the interface.
7.
Switch to the measured value display with
<F1>
