PROBE DELAY

Every probe is equipped with a delay line between the
transducer and the coupling face. The sound pulse must
first pass through this delay line before it can enter the
test object. You can compensate for this influence of the
delay line in the probe in the function PROBE DELAY.
You can set the probe delay by coarse adjustment steps
or by fine adjustment (see Section Coarse adjustment
and fine adjustment, page 4-11).
The adjustment range is 0 ... 1000.000 µs.
N o t e
If the value for the probe delay is not known,
please read Chapter 5.8 Calibrating the
USM 36, page 5-28 to determine this value.
– Select the function PROBE DELAY.
– Set the probe delay.
– Press the two arrow keys Left and Right simultane-
ously in order to set the value to zero.
