7.2.4 1-point calibration
Calibration in water vapor-saturated air (
Cal
) and calibration via
Comparison
meas.
according to the Winkler method (
Comp
) are described jointly here.
1.
Connect the IDS D.O. sensor to the meter.
2.
Check the selected calibration type and selected number of calibration
points in the sensor setting menu and, if necessary, change them.
3.
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.
4.
Start the calibration with
<CAL>
.
Cal
(calibration in water vapor-saturated air) or
Comp
(calibration via
Comparison meas.
according to the Winkler method) is displayed.
The calibration point (DO Sat) is displayed.
5.
Start the measurement with
<MENU/ENTER>
.
The measured value is checked for stability (stability control).
The [AR] status indicator is displayed. The measured parameter flashes.
