ESTABLISHING THE ANGLE OF GROUND SLOPE
If the ground is not level, the detector will need to be tilted at the same angle.
The graph below gives the angle of the ground slope by measuring the rise
(or fall) 10 metres and 20m from the detector.
Packing dimension for a specific angle is given in the following graph.
MASKING
There is one central main beam and four short range beams.
To mask off the short range beams fit a 20mm wide 10mm high
rectangle in the bottom LH & bottom RH corner of lense.
