Die vorliegende Erfindung betrifft ein Verfahren und eine Vorrichtung zur Verfolgung eines Retroreflektors. Dabei emittiert eine Lichtquelle ein Mess-Lichtbündel in Richtung des Retroreflektors. Zumindest ein Teil des zurückreflektierten Mess-Lichtbünde...

The transmitting device has an energy storage unit (15) that is provided in the position-measuring device (10). The energy storage unit is charged in the charge mode through the line pair (110) and is provided to supply energy to the position-measuring dev...

The method involves increasing direct current voltages (+U-ZL, -U-ZL) by a step-up converter circuit (H), if the direct current voltage is lower than a peak-to-peak maximum of a network voltage (U-Netz). Intermediate circuit voltages (+U-ZH, -U-ZH) are low...

The device has an electrically powered sensing device for sensing a measurement object and generating an output signal and a battery holder with electrical connections for contacting electrical contacts of a battery arrangement. The battery holder (2) enab...
