NOTE 1 – Applies to measurements taken using the same grip force for each part.

NOTE 2 – Applies to measurements taken using the same grip force for each part and also using the same grip force to establish the reference offset.

NOTE 3 – Fingers can be re-positioned by loosening two screws and using mounting pin locations. Custom fingers can be installed for wider adjustment range.

NOTE 4 – Gripping force is bi-directional; parts may be gripped on their inside or outside surfaces using appropriate fingers.

NOTE 5 – Maximum may be higher depending on finger friction and force setting.
