For this calibration procedure, the
Comparison meas.
setting must be set to
On
in the
Calibration
menu.
4.
Start the measurement with
<ENTER>
.
The measured value is checked for stability (stability control).
The [AR] status indicator is displayed. A progress bar is displayed and
the display of the measured parameter flashes.
5.

or
<ENTER>
, switch to the measured value dis-
play.
The meter displays a D.O. saturation of approx. 101.7 % in the air cali-
bration vessel.
Before calibrating via a comparison measurement, the sensor
should be calibrated in the air calibration vessel.
1.
Connect the D.O. sensor to the meter.
2.
Immerse the D.O. sensor in the reference solution.
3.
Start the calibration with
