Procedure for calibrating with the air calibration vessel OxiCal®-SL:
Procedure for calibrating via a comparison measurement:
Note

Keep the OxiCal
®
-SL air calibration vessel ready.

Connect the D. O. sensor to the measuring instrument.

Put the D. O. sensor into the air calibration vessel.

Press the <CAL> key repeatedly until O
2
CAL appears.

Press <RUN/ENTER>. The AutoRead measurement begins.
The value of the relative slope of the sensor is displayed.

As soon as the measured value is stable, the instrument displays the
sensor evaluation.

Switch to the measuring mode with <M>.


Connect the D. O. sensor to the measuring instrument.

Press the <CAL> key repeatedly until O
2
FAC appears.

Immerse the oxygen sensor in the calibrating solution.

Press <RUN/ENTER>. The AutoRead measurement begins.

If the measured value is stable, the instrument displays the determined
measured value and the correction factor of the relative slope (initial
value = 1.000).

Remove the oxygen sensor from the calibrating solution.

Perform a comparison measurement (determine the nominal value).
Leave the measuring instrument switched on until the nominal value is
determined.

Set the displayed value on the measuring instrument to the nominal
value with <
▲
> <
▼
>. This changes the related correction factor of the
relative slope.

Switch to the measuring mode with <M>.
