Krautkramer USM 35X Issue 01, 04/2005 5-7
Operation
Adjusting the display range (function group BASE)
Frequency range Adjustment range (c = 5920 m/s)
0.2 to 1 MHz 0.5 to 9999 mm/0.02" to 390"
0.5 to 4 MHz 0.5 to 9999 mm/0.02" to 390"
0.8 to 8 MHz 0.5 to 1420 mm/0.02" to 50"
2 to 20 MHz 0.5 to 1420 mm/0.02" to 50"
– Select the function RANGE .
– If required, toggle between coarse and fine adjust-
ment.
– Adjust the required value by means of the right-hand
rotary knob.
MTLVEL (Sound velocity)
Use MTLVEL to set the sound velocity within the test
object. You can use sound velocities between 1000 and
15000 m/s.
• Coarse adjustment, in steps as follows (m/s):
15000 9000 5000 2000
14000 8000 4000 1600
13000 7000 3250 1450
12000 6320 3130 1000
11000 6000 3000
10000 5920 2730
• Fine adjustment
1000 ... 15000 in steps of 1 m/s

Attention:
Always ensure that the function MTLVEL is correctly
set. The USM 35X calculates all range and distance
indications on the basis of the value adjusted here.
– Select the function MTLVEL .
– If required, toggle between coarse and fine adjust-
ment.
– Adjust the required value by means of the right-hand
rotary knob.
D-DELAY (Display starting point)
Here you can choose whether to display the adjusted
range (for example 250 mm) starting from the surface
of the test object, or in a section of the test object
starting at a later point. This allows you to shift the
complete screen display and consequently also the
display zero.
