Patent ID: 7199866

Claim:
An extreme value measuring process of a handheld laser distance measuring device ( 1 ), wherein, in a first step, an input means ( 2 ) is actuated that triggers a measurement sequence, during which, in a second step, individual measurements of distances to a plurality of different measurement points along a measurement path ( 10 ) are made triggered by the handheld laser distance measuring device ( 1 ) and, in a third step, one of at least one maximum value ( 4 ) and one minimum value ( 5 ) relative to the measurement sequence is determined by the handheld laser distance measuring device ( 1 ) from the individual measurements, wherein an extreme value difference ( 6 ) relative to the measurement sequence is automatically calculated by the handheld laser distance measuring devices using at least one minimum value ( 5 ) and at least one maximum value ( 4 ); wherein, in the second step, the measurement path ( 10 ) covers at least in part a surface ( 9 ) and an object ( 8 ) arranged in front of said surface ( 9 ); and wherein, in a further step, the computed extreme value difference ( 6 ) is displayed directly on a display means ( 4 ).
