Temperature Offset
It is recommended to check the reading of the
PT100 temperature sensor periodically in a water
bath of known temperature. This is especially
important if a concentration unit (like µmol/L or
mg/L) was selected for the oxygen readings (see
chapter 6.2.3). A manual Temp. Offset can be entered for a 1-point
calibration of the temperature sensor (default: 0).
It is also possible to prepare a water-ice-mixture
giving 0°C, where at least 50 mm of the
temperature sensor tip is submerged. Wait for
steady state, read the measured temperature in
the top screen of the Live Mode, and enter it as a
negative Temperature Offset. After this, a new calibration of the
connected oxygen sensor must be performed (see chapter 6.3).
Changing the temperature offset will lead to a loss of the oxygen
sensor calibration.

Device Info and Reset Device
Information concerning the unique ID number of
the device, the number of saved log files, the used
space of the internal device memory (MB) and the
firmware version can be obtained by selecting
Device Info.
Reset Device can be used in order to reset all settings and
calibrations. Additionally it can be selected, whether to delete also
all log files on the internal device memory (Delete All) or to keep
them (Keep Data).
