Krautkramer USM 35X Issue 01, 04/2005 5-33
Operation
Calculation of flaw position (function group TRIG)
COLOR
To make the orientation easier, the instrument is able to
display the different sound path sections or legs in dif-
ferent ways. You can choose between two display modes:
• 1 – The A-scan is shown in another color in every leg.
– Leg 1 in magenta
– Leg 2 in blue
– Leg 3 in magenta
• 2 – The legs are shown as background shadings.
• off – No legs are displayed.
– Select the function COLOR .
– Use the right-hand rotary knob to set the required
mode.
THICKNE (Material thickness)
Use the THICKNE function to set the material’s wall
thickness. This value is required for the automatic cal-
culation of the real depth.
Adjustment range: 1 ... 1000 mm/0.05 ... 400"
– Select the THICKNE function.
– Use the right-hand rotary knob to set the required value.
DIAMET (Outside diameter of the test object)
You will need the DIAMET function for tests on circular
curved surfaces, for example when testing longitudinal-
ly welded tubes. In order to make the USM 35X carry
out the corresponding correction of (reduced) projection
distance and depth, you should enter the outside diam-
eter of your test object in this function.
If you plan to carry out the flaw position calculation for
plane-parallel (flat) test objects, the
DIAMET function
should be set to flat .
Adjustment range:
• 10 ... 2000 mm/0.4 ... 800"
• flat
– Select the DIAMET function.
– Use the right-hand rotary knob to set the required
value.
