7. Put the IDS D.O. sensor into the calibration medium.

When calibrating via comparison measurement (Comp):
Put the IDS D.O. sensor into the reference solution..
 When calibrating in water vapor-saturated air (Cal):
Put the IDS D.O. sensor into the calibration vessel with water vapor-
saturated air.
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 <ENTER>.
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
<ENTER>.
The calibration record is displayed and output to the interface.
10. Switch to the measured value display with <ENTER>.
