7.3.3 Calibration procedure
Calibration in water vapor-saturated air.
To calibrate the
FDO
®
925 use the calibration and storage beaker.
7.3.4 Calibration in water vapor-saturated air
Proceed as follows to calibrate the D.O. sensor:
Stability control
(AutoRead)
In calibration, the Stability control function (AutoRead) is automatically acti-
vated.
1
Connect the D.O. sensor to the meter.
2
Place the
FDO
®
925 oxygen sensor in the check and storage beaker.
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 completed (status indicator
[HOLD][AR]) or
accept the calibration value with
<ENTER>
.
The calibration record is displayed and output to the interface.
6
Switch to the measured value display with
<ENTER>
.
