Sensitivity correction

You can use the function TRANSFER CORR. to com-
pensate for transfer losses in the material to be tested.
A correction is necessary if the test object and the refer-
ence standard have different surface qualities.
You have to determine the adjustment value for the
compensation of transfer losses by way of experiment.
In this connection, the gain is varied accordingly but the
curve shape remains the same.
– Select the function group MAT ATTN.
– Select the function TRANSFER CORR. and set the
required value.
