3. The Plus key 3-6 or the Minus key 3-9 is pressed to select the material code for
measuring. Then the material selection button 3-5 is pressed to confirm. The
measuring instrument changes to the measuring mode, '0' appears in the
display. If a material code is selected without confirming this selection, the
instrument will automatically return to the measuring mode after a few seconds.
In this case, the meter will still retain the old material code before switching off
completely.
4. A
4-digit
number
is
shown
on
the
display:
If the plus key 3-6 is pressed, it will display 'cd11' or if the minus key 3-9 is
pressed, it will display 'cd01'. The 4-digit number represents the last ultrasonic
speed
defined
by
the
user.
By changing the ultrasonic velocity, varying material properties can be
compensated.
5. Once the material code has been selected and stored, it is stored in the
instrument memory. As long as no change is made, the meter always uses this
material code.
