ROMER Absolute Arm accuracies
The following data represent the accuracies of the different sizes and levels of ROMER
Absolute Arm.
All the values refer to the ASME B89.4.22 standard and are displayed in millimetres.
All probing specifications are achieved with a ROMER Absolute Arm mounted on a base plate
or magnetic base plate and using a 15mm steel ball probe with a length of 50mm under stable
environment conditions.
