8.2.6 Calibration data
Displaying the
calibration record
The calibration record of the last calibration is to be found under the menu item,
Calibration / Calibration record. To open it in the measured value display, press
the key.
The calibration records of the last 10 calibrations are to be found in the menu,
Calibration / Calibration data storage / Display. To open the Calibration menu,
press the key in the measured value display.
As the calibration vessel use a BOD bottle that contains a
small amount of clean water (approx. 40 ml).
The sensor must not be immersed in the water.
Leave the sensor in the calibration bottle long enough (5
to 10 minutes) so that the air is water vapor-saturated and
the sensor can adapt to the ambient temperature.
8. Start the measurement with .
The measured value is checked for stability (stability control).
The [AR] status indicator is displayed. The measured parameter flashes.
9. Wait for the AutoRead measurement to be completed (audio signal).

When calibrating in water vapor-saturated air (Cal):
The calibration record is displayed and output to the interface.
 When calibrating via comparison measurement (Comp):
Set the concentration value with <> <> and accept it with
.
The calibration record is displayed and output to the interface.
10. Switch to the measured value display with .
The calibration record is automatically transmitted to the interface
after calibrating.
