8 Typical operating sequence
The Quarryman Pro can be used for a wide variety of jobs in a variety of applications. However, the following section
gives the step-by-step routine for a typical face profiling operation, including a resection. It might be regarded as a
template for any simple operations with the unit and can be modified according to specific project or site
requirements.
8.1 Positioning the Quarryman Pro
Set up the instrument, ideally at a distance of less than 100 m from the face to be profiled.
Find the best location where all parts of the face are clearly visible. It may occasionally be necessary to have two
or more instrument set-ups to ensure complete coverage of the face during scanning operations.
Many quarries will have a series of survey stations around the perimeter. Each station is marked by a permanent
target, visible from the quarry floor. The coordinates (x,y,z) of each marker will be known on either a national or
local grid system. There should be enough markers to ensure that wherever the Quarryman Pro is situated, at least
three stations will be visible. These stations can be used to carry out a resection. The resection enables the software
to calculate the position of the Quarryman Pro within the quarry.
Check that at least three survey stations can be seen. These should ideally be fairly evenly spaced around the
instrument location. If they are all clustered in the same direction, the results of the resection observations may be
poor.
Check that he set-up location will not be disturbed by other personnel or vehicles during the duration of the profiling.
8.2 Setting up the Quarryman Pro
Set the tripod on stable ground and ensure that each leg is secure.
The legs of the tripod should be roughly equidistant and the height should be such that, with the instrument mounted
on the tripod, the telescope will be at eye level.
Tighten each leg screw securely at a point where the flat top off the tripod is roughly level.
Mount the instrument on the tripod using the tribrach and tighten the screw to secure the instrument to the tripod.
Ensure that the latch on the side of the tribrach is engaged and holding the instrument securely.
Turn the yoke of the Quarryman Pro so the axis of the unit is parallel to two of the three tribrach screws. Using these
two foot-screws, level the instrument in one axis. Observe the bubble on the yoke to check when the instrument is
level.
Turn the yoke 90° so the axis of the unit is perpendicular to the first two tribrach screws. Now use the third screw to
level the instrument in this second axis.
Repeat this stage with the instrument turned 180° to fine-tune the levelling of the Quarryman Pro.
Mount the battery on the tripod using the bracket on the rear of the battery pack.
Connect the power cable between the 4-pin connector on the battery pack and the connector on the base of the
Quarryman Pro.
Ensure that the USB drive is securely inserted in the instrument.
Measure the height of the instrument with a tape measure. The instrument height is the vertical distance from the
