Ensure that the target surface is 'square' to the laser

Check that it is held vertically by using the bubble embedded in the top of

the pole – a 1mm offset of the bubble from the centre of the vial
translates approximately to a 0.5mm error in the X-Y measurement
The Pointed Foot and Rounded Foot click into the bottom of the Target Pole and
are interchangeable. When using the Target Pole on its own, it is advisable to use
the Rounded Foot to minimise wear to the Pointed Foot (refer to Section 7.2).
When using the Target Pole with the Rail Pole, the Pointed Foot must be fitted.
When measuring the location of an adjacent track, the Rail Pole allows the
Pointed Foot to be located accurately on the gauge corner of the rail.
1. Place the Rail Pole on the track to be measured
2. Ensure that the Rail Pole is located 'squarely' across the track and that it
is firmly located against the rail being measured
3. Locate the Pointed Foot in the socket in the Rail Pole
