2. Tref (reference temperature) is defined in the Temperature Compensation menu. If
Tref is between T1 and T10 then the value of Tref needs to be entered as Tx (T2....T9).

The matrix can be cleared before
entering new values. Next new matrix
values can be entered as described
above. The SC450G can interpolate the
matrix. During this process it will check
if the matrix is completely ascending/
descending. This is necessary as
otherwise the lookup function can give
two results for one temperature. If an
error is found, the SC450G will specify
the location of the error as shown in the
user interface screen “user defined 1/2”.
The backspace key should be used for
deleting an individual matrix value.
An empty value is shown as
