Preliminary
F.6 Oil Correction Table
In the Setup it is possible to make a measurement correction of the PF / tan δ on the basis of the

In the Setup you have access to this menu.

correction table.

The file looks like IEEE C57.12.90.oct 1 . It is on the root of the USB-key. You can edit the file e.g.
with a text editor, Microsoft Excel, Libre Office Calc etc.
This is an Example of an Oil Correction
Table.
It is possible to add customer tables
tailored to the specific oil or test object.
1 The standar td table was from the IEEE C57.1290, you see the correction factor for the tan delta at the specific temperature
(between it' s an interpolation). This table is depending from the test object and it's not really an accurate correction. Now it's not any
more in this standard, but some customers still want to have it, that's why we use a service code for it.
