Figure 17 : Alignment Adjusters
When adjusting the alignment nuts to achieve maximum signal, it will be seen that when maximum
signal is achieved the locking alignment nuts will continue to turn in the same direction before the
signal starts to fall off, thus there is a maximum signal strength ‘plateau’.

It is very important that before locking the alignment/locking nuts the centre of this plateau must be
found. When the first maximum peak signal is achieved continue to turn the alignment/locking nut in
the same direction, making note of adjustment made, before fall-off is achieved, i.e. one turn of the
nuts. In this case the plateau is therefore one turn of the locking nuts long and should be turned back a
half-turn to meet the centre point of the plateau. At this point lock the alignment and locking nuts very
tight! Once the locking position is achieved in the vertical plane the process must be repeated in the
horizontal plane.
c) Select ‘Detector waveforms’ in the Function box and the following screen should appear:
Thermal barrier
Sensor head
alignment stud
Sensor head mount
This gap should be
equal all round
Sensor head mounting bolts
Alignment flange
Alignment nuts (note that
these nuts are a different
thread pitch to others used
by CODEL and should
therefore be kept separate)
