Display test appears briefly on the display.
The relative slope for the sensor type that was just connected subse-
quently appears for approx. one second.
After this, the measuring instrument automatically switches to the mea-
suring mode. The display shows the relevant measured value.

Special functions:
The AutoRead function checks the stability of the measurement signal. Acti-
vate AutoRead with <AR>. The current measured value is frozen. Thus, the
<AR> key can also be used as a "hold function" to freeze the measured val-
ues. Press <RUN/ENTER> to start the AutoRead measurement. During the
AutoRead measurement, AR flashes on the display until a stable measured
value is reached.
The measuring instrument automatically measures the temperature of the
sample with the integrated temperature probe of the conductivity measuring
cell (display shows TP).
There are several measuring ranges available for oxygen measurements.
If a measuring range limit is exceeded, AutoRange causes the measuring in-
strument to change automatically to the next measuring range.
The oxygen concentration measurement of seawater requires a salinity cor-
rection. The portable instrument Oxi 315i calculates the measured value us-
ing a salinity value of 30.0. Press the <RUN/ENTER> key while pressing the
<M> key to switch the salinity correction on and off. While the salinity correc-
tion is switched on, the function display Sal appears on the display.
