Method for operating a display device driven by at least one stepping motor with display scales, having the following steps: determining suitable step widths at least in ranges affected by stroboscopic flicker effects when driving in each case one stepping motor for moving the display scale in a measuring run when starting the instrument or on request, storing the determined step widths in the form of a matching parameter, and operating the stepping motor(s) with a suitable step-width resolution in the ranges that are identified as affected by the stroboscopic flicker effects to be avoided.

The invention concerns a compass having an electro magnetic half-shell transformer energy transmission and opto electronic data transmission. To avoid a slipring connection during the transfer of supply voltage at least one winding on the primary half-shell is connected to a controllable input voltage source via a H-bridge circuit, and at least one secondary winding having taps is provided at the other half-shell coil.

The invention refers to a process for scanning a gyroscopic instrument. The invention is characterised by the collection of gyroscopic data being effected by true angle scanning. In order to apply the process of the invention, a gyroscopic instrument including a gyroscopic scanning system is required in which the gyroscopic scanning system is coupled with a rotating, scanned and/or scanning unit. The process may also refer to a gyroscopic instrument including a gyroscopic scanning system in which a scanning module (such as a CCD sensor) is arranged on the side of the gyroscopic instrument as a scanning device, directly scanning horizontal and vertical true angle identifications on a gyroscopic instrument.
