2.12 PDA 50 / 51 / 52 target plate
The PDA 50 target plate is made of durable plastic with a special reflective coating. Use of the target plate is
recommended at distances greater than 10 m in poor light conditions.
The PDA 51 target plate has no reflective coating and its use is recommended in poor light conditions and at short
distances. The PDA 52 target plate is equipped with the same reflective coating as the PDA 50 but is considerably
larger in size (A4 format, 210 x 297 mm). This makes it much easier to aim the tool at the target plate over long
distances.
NOTE
For reliable distance measurements, care should be taken to ensure that the laser beam strikes the target plate at
right angles as far as possible. The laser spot on the target plate and the measuring reference point (starting point)
may otherwise be in different planes (parallax error).
NOTE
When the target plate is used and very high accuracy is required, 1.2 mm should be added to the measurement
obtained.

2.13 PDA 71 measuring extension

The measuring extension is made from aluminium and is equipped with a non-conductive plastic grip. The screw on
the measuring extension should be screwed into the threaded bush on the rear contact surface of the PD 42. 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).
