Proceed as follows to calibrate the D.O. sensor:
7.3.5
Calibrating with
Comparison meas.
(e.g. Winkler titration)
With the calibration procedure
Comparison meas.
, the measured value of the
sensor is adjusted to the nominal value of a comparison solution via a correc-
tion multiplier. The current correction multiplier is documented in the sensor
menu (
i
Factor =
x.xxx
) and in the calibration record.
For this calibration procedure, the
Comparison meas.
setting must be set to
on
in the
Calibration
menu.
1.
Connect the D.O. sensor to the meter.
2.
Put the D.O. sensor into the calibration vessel.
3.
For
FDO 4410
with the check and storage vessel FDO Check:
Close the check and storage vessel
FDO Check
.
Leave the sensor in the calibration vessel or check and storage
vessel (
FDO 4410
) long enough (at least 15 minutes) until the air is
saturated with water vapor and the sensor has adapted to the
ambient temperature.
4.
Start the calibration with
<CAL>
.
5.
Start the measurement with
<ENTER>
.
The measured value is checked for stability (stability control).
The [AR] status indicator is displayed. The measured parameter flashes.
6.
Wait for the AutoRead measurement to be finished (beep, [HOLD][AR]
status indicator).
The calibration record is displayed and output to the interface.
7.
Switch to the measured value display with
<F1>
