6.4.2  Calibration/Adjustment Methods

• Automatic calibration: Automatic with standard calibration solution

• Manual: Manual entry of a calibration solution

• Product: Product calibration (calibration with sampling)

• Data entry: Data entry of premeasured sensors

• Temperature: Temperature probe adjustment

6.4.3  Calibration Mode: Automatic

Automatic Calibration with Standard Calibration Solution

During automatic calibration:, the conductivity sensor is immersed in a standard calibration solution
(NaCl or KCl, set during parameter setting in the 

Cal Presettings

 submenu). On the basis of the 

measured conductance and temperature, Stratos Multi automatically calculates the cell constant. 
The temperature dependence of the calibration solution is accounted for.

Notes on Calibration

• Use only fresh calibration solutions. The used calibration solution must be configured.

• The accuracy of the calibration is crucially dependent on a precise acquisition of the calibration so-

lution temperature. On the basis of the measured or entered temperature, Stratos Multi calculates
the setpoint of the calibration solution from a stored table.

• Note the response time of the temperature probe.

• To determine the exact cell constant, wait for temperature equalization of the temperature probe

and calibration solution before calibration.

Note: 

Note during calibration: If the measured conductance or temperature fluctuate greatly, 

the calibration procedure is aborted after approx. 2 min. Repeat calibration if an error message 
appears.

Calibration Procedure

Calibration

[I] [II] … Cond

When you access calibration, the calibration values selected in the calibration presettings are used.
These settings can still be changed in the Calibration menu. If you do not want to perform calibration,
use the left 

softkey

 to go back one level and abort the calibration.

01.

Select “Automatic” calibration mode and press 

enter

 to confirm.

✓

Display of calibration solution as configured in 

Cal Presettings

.

02.

Change the calibration solution, if required.

03.

Take the sensor out of the medium and rinse it well in deionized water.

04.

Immerse the sensor in the calibration solution.

05.

Start calibration with the 

right softkey: Next

.

✓

Calibration is performed. 
The following parameters are displayed: Calibration temperature, solution table value 
(conductivity depending on calibration temperature), and response time.

Result

✔

By pressing the 

right softkey: Adjust

, the calibration values obtained during calibration for 

calculation of the process variables are applied to the device. When using a Memosens sensors,
the calibration values are saved in the sensor.
