Sensitivity correction
You can use the function Transfer Correction 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.
Adjusting reference lines
You can change the reference lines SL, RL and EL at
any time. The dB values always refer to the reference
line during recording. These values can also be positive,
i.e. positioned above the reference.
– Select the function SL and change the Sizing Line as
required.
– With the functions RL and EL adjust the Recording
Line and the Evaluation Line in the same way.
