  • Control device of a position measuring system
    Patent number: 6807499
    Abstract: A method for generating an indication regarding the amplitude level of at least one scanning signal of a position measuring system by determining an amplitude level of at least one scanning signal of a position measuring system, generating an amplitude signal based on the determined amplitude level. Forming a deviation signal by comparing the generated amplitude signal with a predetermined nominal signal and providing an indication of a proper set-up of a scanning head of the position measuring system as a function of the deviation signal, wherein with a weak deviation signal, a change in the deviation signal causes a small, or no variation of the indication, and in contrast thereto a larger variation of the indication is caused by a stronger deviation signal.
    Type: Grant
