A measuring system for calibrating a machine in which a base ( 10 ) is attachable to a surface of the machine and a housing ( 20 ) is mountable on the base, wherein at least one surface of the base and at least one surface of the housing are each provided with a complementary part of a mounting device, such that when the two parts of the mounting device are connected together, the housing may be aligned in any of a plurality of predetermined directions. The base includes a lifting mechanism ( 64 ) which when lowered allows the complementary parts of the mounting device ( 93, 95 ) of the housing ( 20 ) and the base ( 10 ) to be in contact and when raised causes them to at least partly break contact with one another. The level of the base ( 10 ) may be adjusted using a system of members and tapered rollers.
