5.4.6 Conductivity calibration
Please note
The conductivity sensor has an integrated temperature sensor and
therefore an automatic temperature compensation feature.
In the conductivity calibration menu, the temperature of the
temperature sensor in the conductivity sensor can be adapted with
the parameter "Cal. temperature" to a comparative measurement.
1 Starting from the basic display in the main menu select the
"Calibration" menu.
2 Select the "Conductivity (1) ... (4)" menu item.
3 Select the "Calibration" parameter.
4 Place one of the supplied beakers into the bottom clip and fill
with the buffer solution "60.0mS/cm"* or clamp a bag with
buffer solution "60.0 mS/cm"* into the bottom clip.
5 Pull or unscrew the conductivity sensor from the lid of the cell
body.
6 Dip the conductivity sensor through the top clip into the
calibration solution to the bottom of the beaker.
7 Pull out the conductivity sensor and rinse off with distilled
water.
8 Repeat the dipping and rinsing procedure several times.
9 Replace the calibration solution in the bottom beaker with a
new solution.
10 Repeat measurement. Move the conductivity sensor slightly
until the displayed value remains constant.
11 Use the arrow keys to enter the determined value.
12 Save the value by pressing "Enter".
13 Insert or screw the conductivity sensor into the lid of the cell
body.
14 Conductivity calibration is then concluded.
* Depends on measuring range:
600 µS/cm calibration solution for 2500 µS/cm measuring range
60 mS/cm calibration solution for all mS/cm measuring ranges
