5.3.2 When to calibrate?

After connecting a sensor

Routinely within the framework of the company quality assurance

When the cleaning interval has expired

5.3.3 Determining the cell constant (calibration in control standard)

You can determine the actual cell constant of the IDS conductivity sensor by 
calibrating with the control standard in the following range:
0.450 ... 0.500 cm

-1

 (e.g. 

TetraCon 925

, nominal cell constant 0.475 cm

-1

)

The cell constant is determined in the control standard, 0.01 mol/l KCl. 

In the default condition, the calibrated cell constant of the IDS sensor is set to 
0.475 cm

-1

 (IDS conductivity sensor 

TetraCon 925

).

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 control standard solution, 
0.01 mol/l KCI.

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 ([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 

<ENTER>

.
