Conductivity data not being recorded with measurement units

[Tone]

First my hardware:

Now my Conductivity probe (PL) settings:

Conductivity graph:

Problems:

(1) Profilux records data, but does not record the unit of measurement.

(2) When data is graphed, there is no unit of measurement ... and, the data appears to fluctuate significantly (with water temperature?). Should show a pretty much straight line.
