5 Operation Setting the display range (function group RANGE)
5-10 Issue 2 (12/2013) USM 36
RANGE
You can use the function RANGE to set the range (the
display range) for making measurements.
You can set the display range by coarse adjustment
steps or by fine adjustment (see Section
Coarse ad-
justment and fine adjustment , page 4-11).
The adjustment range is 0.5 … 20000.00 mm.
Note
The adjustment range for display range
depends on the sound velocity setting and
on the frequency range setting (function
FREQUENCY in the function group
RECEIVER ).
– Select the function RANGE .
– Set the required display range.
– Press the two arrow keys Left and Right simultane-
ously in order to quickly set a mean value
(254.00 mm).
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.
Note
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.
