One speed declines near the first precalculated position of the pump housing, and drives at a slow speed signal so that described sensor first makes a reservation for from this
Position drops to the described test point of the pump housing with the second speed less than First Speed.
16. methods as claimed in claim 15, it is characterised in that
Described lifting actuation step includes the first feedback step, drops to described first precalculated position and institute at described sensor
When stating test point, output feedback signal respectively.
17. methods as described in any one of claim 13-16, it is characterised in that
In described rate-determining steps, control described torsion drive circuit and export two driving signal so that described sensor is being carried out
Test first carries out position rotating before rotating.
18. methods as claimed in claim 17, it is characterised in that
The the second driving signal controlling the output of described torsion drive circuit includes position drive signal so that described sensor is first
Rotation navigates to the second precalculated position, and rotation driver signal so that described sensor carries out test and rotates.
19. methods as claimed in claim 18, it is characterised in that
Described torsion actuation step includes the second feedback step, at described sensor rotation to described second precalculated position and complete
When becoming test to rotate, output feedback signal respectively.
20. methods as described in any one of claim 17-19, it is characterised in that
If the result of torsion-testing shows that test result is defective, in the most described rate-determining steps, export repetition measurement signal so that described
Torsion drive circuit output repetition measurement drives signal, so that described sensor carries out the repetition measurement rotated a circle.
21. methods as claimed in claim 20, it is characterised in that
Described rate-determining steps farther includes alarming step, if repetition measurement result is still defective, then and output alarm signal.
22. methods as described in any one of claim 18-21, it is characterised in that
Described rate-determining steps includes return phase, after a test, controls lifting drive circuit and the output of torsion drive circuit drives
Signal, the startup position before driving described sensor to be returned to test.
