Conductivity calibration
Please note
The conductivity sensor has an integrated temperature sensor and
therefore an automatic temperature compensation feature.
Proceed as follows:
1
Starting from the main screen, press the menu field with mea-
suring value „Conductivity“.
2
Select the menu field “Calibration”. The “Conductivity - Cali-
bration" window appears on the graphic display.
3
Select the parameter “Cal. value”.
4
Place the beaker into the bottom clip and fill with approx. 25 ml
of the calibration solution “60.0mS/cm” or clamp a bag with
calibration solution “60.0 mS/cm” into the bottom clip.
5
Close the sample water inlet and outlet (for pressurized ver-
sion of the flow cell only) and open the sample taking unit
(drain) briefly. Close the sample taking unit (drain) once more.
6
Pull or unscrew the conductivity sensor from the cover of the
cell body of the flow cell.
7
Dip the conductivity sensor through the top clip into the cali-
bration solution to the bottom of the beaker.
8
Pull out the conductivity sensor and rinse off with distilled
water.
9
Repeat the dipping and rinsing procedure several times.
10
Replace the calibration solution that is in the bottom clip with a
new one.
11
Repeat the measurement. Move the conductivity sensor
slightly until the displayed value remains constant.
12
Use the keypad to enter the value to be calibrated.
13
Confirm the entry with the Enter key.
14
Insert or screw the conductivity sensor into the cover of the
cell body of the flow cell.
15
Open the sample water inlet and outlet once more (for pres-
surized version of the flow cell only).
Conductivity calibration is then concluded.
