Abstract:
A method for operation of a position measuring device, which comprises a scanning unit that defines a scanning plane and a measuring graduation that defines a measuring graduation plane, said scanning unit and said measuring graduation are movable relative to one another during a measurement operation, and position-dependent output signals are generated during scanning performed by said scanning unit, said method comprising:regulating said position-dependent output signals to constant signal amplitudes by action on a controlling variable; ascertaining a value of said controlling variable required for said regulating; converting said value of said controlling variable into a digital signal suitable for serial transmission; transmitting said digital signal in a defined serial transmission protocol to an electronic evaluation unit downstream of said position measuring device via a transmission device; displaying said converted value of said controlling variable; and setting a scanning spacing between said scanning plane and said measuring graduation plane with the aid of said displayed value of said controlling variable, which acts as a measure for a current scanning spacing for setting a predetermined, optimal scanning spacing.
