Patent ID: 10684127

Abstract:
A measuring device (10) has two measuring units (12), (13), each having a probe unit (16), (35). Each probe unit has a probe element (18), (37) having, in a probing direction (x), an outer probe side (18a) or (37a) and an inner probe side (18i) or (37i). To determine a zero position or a reference plane (B) at right angles to the probing direction (x), the two probe elements can be brought into contact via their respective outer probe sides (18a), (37a) or their respective inner probe sides (18i, (37i). As soon as contact between the associated probe sides (18a), (37a) or (18i), (37i) is detected, a reference plane (B) is defined as zero position in the probing direction (x) using the point of contact between the two probe elements. The zero position can thus be determined without calibrated standards or block gauges.
