Hope you are well.
Akihiro is out of the office.
As far as you select any of built-in table (c.f. Brix, Alcohol OIML 15
degreeC), the table will do temperature compensation as well as
concentration calculation.
So even if measurement temp. is 22 degreeC, as far as you select Brix as
Meas. Unit, you'll get Brix at 20 degreeC shown as a result.
There is no further setting needed.
