2.13 PDA 71 measuring extension
The measuring extension is made from aluminium and is equipped with a non-conductive synthetic rubber grip. The
screw on the measuring extension should be screwed into the threaded bush on the rear contact surface of the PD
40. When the measuring extension is screwed onto the tool, the rear reference is then relocated to the tip of the
measuring extension, i.e. the rear reference is extended by 1270 mm (50 inches).
