7. Find the position of the weld seam and enter the deviation from the nominal position (in
parameter ”
position offset
“).
8. Press the < Start test job > key.
9. Check the position of the weld seam and correct the parameter “ Position offset ” (if required).
10. If the position of the weld seam matches with the nominal position, turn the sample tube for
180° and repeat the test run. In case of deviation from the nominal position change the
parameter “ Position offset ” for half of the deviation.
11. Repeat the test run in both orientations, the same error angle should result.
12. Check the parameter ”
Detection quality “.
The default value ”very good “ is only practicable for measuring results “very good detection“
and “good detection“ . For measuring results “s atisfactory detection “ the parameter “ Detection
quality “ should be set to “ good ” or “satisfactory” .
13. If the error angle is too large, if no satisfying positioning could be reached or if the unit shows
error messages (e.g. ”slippage too high“ ), please refer to the chapter “ Optimizing the weld
seam positioning “.
14. Press the < Save > key to store the parameters and exit the mode “ Setup – Edit operation “.
15. With the < Activate program > key the created measuring program will be activated.

7.9 Optimizing the positioning of the Weld seam
If no satisfying results can be achieved with the default settings, the changing of certain parameters
can often cause improvements.
For more details see section “General parameters” and “Special parameters for sensor signal
“Eddy current””.

7.10 Setting-up and changing the system / program password
The passwords for system parameters and program parameters are changed in the same manner.
When entering the password, the system distinguishes between capital letters and regular letters!
1. Press the <
System > key and then the < modify setup > key.
2. If a password is already existing, the password inquiry will appear. Then type-in the current
password and confirm with <Enter>. Only then access to the system settings is permitted.
If no password is existing, the password inquiry will not be called up.
3. Activate the <
Onscreen keyboard
>.
4. With the < Arrow > keys select the “ system password ” resp. the “ program password ”.
5. Enter the new password.
6. With the <
Save > key confirm the entry.
7. If re-starting is required, the system performs it self-acting.
