amplitude curve; said law is
determined by
dB/mm
(
dB/in
)
factor and value of
Probe Delay -
refer to
paragraph 5.7.1 of the
operating manual: at zero material
travel distance (surface) theoretical
DAC
starts at 100% of
A-Scan
height
To enter
dB/mm
(
dB/in
) factor
touch
button then provide
the desired setting. To negate
theoretical DAC touch
then
reduce
dB/mm
(
dB/in
) factor to
