All specifications in relation to B89.4.22.
1 The Point Repeatability Test is the reference test to determine measurement arm repeatability with ball probe. The cone is in front of the machine. Points are measured from multiple approach directions. The average point and the deviation of each point to the average center are calculated. The result is the maximum range divided by two.
2The Volumetric Accuracy Test most accurately represents the reasonable expectations for machine performance in practical measuring applications since it involves measuring a certified length standard many times in several locations and orientations and compares the resultant measurements to the actual length. The Volumetric Length Accuracy Test is the most appropriate test for determining machine accuracy and repeatability. The result is the maximum deviation of the measuring distance less the theoretical length.
3 SI designates the ROMER Absolute Arm with integrated scanner.
4 The Scanning System Accuracy Test most accurately represents the reasonable expectations for machine performance in practical measuring applications while using the laser scanning method. The test consists of measuring a matte grey sphere with 5 different arm articulations. In each articulation of the arm the sphere is scanned from 5 different directions such that the majority of the sphere is scanned. The result is the maximum 3D center to center distance of the 5 spheres.
All probing specifications are achieved with a ROMER Absolute Arm mounted on a ROMER base plate or magnetic base and using a 15 mm steel ball probe with a length of 50 mm under stable environmental conditions.
All RS1 scanning specifications are achieved with a ROMER Absolute Arm mounted on a ROMER base plate or magnetic base and a matte grey calibration sphere of 25.4 mm diameter under stable environmental conditions.
