Calibration via a comparison measurement (e.g. Winkler titration according
to DIN EN 25813 or ISO 5813). At the same time, the relative slope is
adapted to the comparison measurement by a correction multiplier. When
the correction multiplier is active, the
[Factor]
indicator appears in the mea-
suring window.
5.3.4 Calibration in water vapor-saturated air
Use the check and storage beaker (FDO® Check) to calibrate the FDO®
925 sensor.
Proceed as follows to calibrate the D.O. sensor:
1.
Connect the D.O. sensor to the meter.
2.
Place the FDO
®
925 D.O. sensor in the check and storage beaker, FDO
®
Check .
The sponge in the check and storage beaker must be moist (not
wet). Leave the sensor in the check and storage beaker long
enough so it can
adapt to the ambient temperature.
3.
Start the calibration with
<CAL>
.
The last calibration data (relative slope) is displayed.
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 AutoRead measurement to be finished ([HOLD][AR]
status indicator).
The calibration record is displayed and output to the interface.
6.
Switch to the measured value display with
<ENTER>
.
