Follow the instructions on the display.
Display Explanation
* Pull the sensor out of the sample
* Put the sensor in the calibrating
position
Place the sensor in the FDO
®
Check check and storage
vessel.
Select a procedure:
CHECK
CALIBRATION
Select the
CALIBRATION
procedure.
Confirm with <OK>.
Leave the sensor in the check
and storage vessel long
enough so it can adapt to the
ambient temperature (min. 15
minutes).
Press <OK>. The sensor
determines the calibration
data. The display switches to
the measured value display.
The
CAL
indicator flashes
instead of the main measured
value. At the same time, the
momentary relative slope
flashes as the secondary
measured value. The process
ends automatically as soon as
the measured values meet
the criterion for the stability
control. With a great tempera
-
ture difference between the
sensor and the environment,
this may take a while. Subse
-
quently, the main measured
value and temperature are
displayed.
Calibration done.
Calibration is finished.
Confirm with <OK>.
The display returns to the
measured value display.
Step 3:
Bring the sensor into the measuring position.
After the calibration procedure has been finished, the mainte
-
nance condition has to be switched off manually. More detailed
information on the maintenance condition is given in the
IQ S

system operating manual.
