Ultrasound velocity can be adjusted by pressing the Plus- or the Minus- key. By do-
ing this, the value shown in the display is changed higher or lower. First the in-
crease is 10m/ s. If the Plus- or Minus- key is pressed for longer than 4 seconds,
the increase is 100m/ s.
c) A little bit gel has to be dropped onto the material to be measured. Now the sensor
3-7 is pressed onto the surface to be measured. The reading on the display is the
thickness, assumed that coupling is well.
If velocity of a special material is known, it is easy to measure the thickness with the
help of step 7b).
d) Measuring of coatings & materials with an unknown thickness:
A test material of known thickness has to be selected.
Step 7.b) (velocity setting) and 7.c) has to be repeated until the measured value is
exactly the same as the known thickness. In this case the set value is the velocity of
the material to be measured. With this, any number of unknown thicknesses of the
same material can now be measured.
e) To change velocity, VEL- key 3-13 has to be pressed.
To return into the measuring mode, this key has to be pressed again or it has to be
waited until the instrument automatically shows `0`.
f) By using velocity measurement, the coating thickness or the thickness of any hard
And homogenous materials can easily be measured.
12.8 Battery replacement
a) If the battery symbol appears on the display, batteries should be replaced.
b) The battery cover has to be removed from the instrument and the batteries have to
be taken off.
c) Batteries have to be installed, paying carefully attention to polarity.
d) If the instrument is not used for a longer period, batteries should be removed.
