2.1 Intended use

The SD 400 Oxi L is designed for the measurement of dissolved content of oxygen in water.
Suitable oxygen sensors (available in the standard delivery contents) are used for the measure-
ment. The sensor is connected via a 4-pin bayonet connection. The measurement is taken on
the sensor membrane at the end of the oxygen sensor.
Due to the type of sensor used, the instrument must be calibrated regularly to achieve pre-
cise measurement values. The sensor must be regenerated or replaced if necessary before
performing other measurements.
The safety instructions in this operating manual must be observed (see below).
The instrument may only be used under the conditions and for the purposes for which it
was designed.
The instrument must be handled with care (do not throw, drop, etc.) and used in accordance
with the technical data. It must be protected against soiling.

This instrument is built and tested in accordance with the safety provisions for electronic
measurement instruments. The fault-free function and operational safety of the equipment
can only be guaranteed if common, general safety precautions as well as the instrument-
specific safety instructions in this operating manual are observed.
1. Functional and operational safety of the device can only be adhered to under the
climatic conditions specified in the chapter "Technical data".
If the instrument is transported from a cold environment to a warm environment, a
fault of the functionality may arise due to the build-up of condensation. In this case, it
is necessary to wait until the instrument's temperature adjusts to the room temperature

ger, it should be turned off immediately and the potential danger be identified before
the equipment is used again. The safety of the user may be diminished if the instrument
- exhibits visible damages.
- no longer works as specified.
