### Use ISO Calculations

By default, PC-DMIS uses the 1983 ASME standard to perform calculations. This option allows you to switch to the ISO 1101 2004 standard in PC-DMIS 4.0 and higher. The ISO standard calculates the measured value as 2 times the max deviation. In the case of a profile, the tolerance is a diameter zone, all along the profile of the curve. This means the zone isn't just plus tolerance for one side and minus tolerance for the other. Additionally, a given single tolerance value is a diameter, not a radius.

When this value is set to 1 (TRUE), the "Perp to Centerline" flag is disabled. In the FCF dialog box, this is enabled by default. So, if you switch to use the ISO Calculations, the "Perp to centerline" flag is disabled.
