Proceed as follows to calibrate the instrument:

Before calibrating via a comparison measurement, the sensor 
should be calibrated in the air calibration vessel.

1.

Connect the D.O. sensor to the measuring instrument.

2.

Immerse the D.O. sensor in the reference solution.

3.

Start the calibration with 

<CAL>

.

4.

Start the measurement with 

<ENTER>

.

The measured value is checked for stability (stability control).
The [AR] status indicator is displayed. The measured parameter 
flashes.

5.

Wait for the end of the AutoRead measurement or accept the calibration 
value with 

<ENTER>

.

The factor that was set last is displayed.
