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:
5.3.5 Calibration by means of a Comparison meas. (FDO Comp)
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. 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 end of the AutoRead measurement ( [HOLD][AR] sta-
tus indicator).
The calibration record is displayed and output to the interface.
6. Switch to the measured value display with
<ENTER>
