The matrix can be cleared before entering new
values. Next new matrix values can be entered
as described above. The EXAxt can interpolate
the matrix. During this process it will check if
the matrix is completely ascending/descend-
ing. This is necessary as otherwise the lookup
function can give two results for one tempera-
ture. If an error is found, the EXAxt will specify
the location of the error as shown in the user
interface screen above.
The backspace key should be used for delet-
ing an individual matrix value.
An empty value is shown as

1. A minimum number of values is required to make interpolation possible.
The highlighted values marked as are mandatory to enter.
Tref T1 T2 T3 T4 T5
Sol1 S1Tr S1T1 S1T5
Sol2
Sol3
Sol4
Sol5
S5Tr S5T1 S5T5
2. Tref (reference temperature) is defined in the Temperature Compensation menu.
If Tref is between T1 and T5 then the value of Tref needs to be entered as T2 or T3 or T4.
Tref T1 T2 T3 T4 T5
Sol1 S1Tr S1T1 S1T5
Sol2
Sol3
Sol4
Sol5
S5Tr S5T1 S5T5
3. For every SxTx that is entered the following values become mandatory to enter:
SxTr, SxT1, SxT5 and Tx
Tref T1 T2 T3 T4 T5
Sol1 S1Tr S1T1 S1T5
Sol2
Sol3
SxTr SxT1 SxTx SxT5
