Taking a Photo Measurement
To take an accurate Photo Measurement with your Spike, you need to
ensure that:
1) Your target is a at surface and is all on the same plane.
2) Your target is or has a rectangular shape on it (to align the object).
3) Your laser (crosshair on the screen) is pointed at your target. The
crosshair should be on a solid surface and not a window.
4) You are perpendicular
to the target. Photo
measurements taken
from the optimal position
typically see an accuracy
of ± 3%. Please reference
the following target
distance and positioning
guide when taking a Spike
photo.
You cannot measure an object or objects that are on different planes.
Below are some examples.
The bump out
and the side of
the house are on
different planes,
so you cannot
measure the wall
if the laser was
pointed at the
bump out.
The bump out
is on the same
plane that the
laser was pointed
at (red dot), so
measurements
will have higher
accuracy.
The awning and
the wall are not on
the same plane,
so you cannot
measure the wall
if the laser was
pointed at the
awning.
The awning is
on the same
plane that the
laser was pointed
at (red dot), so
measurements
will have higher
accuracy.
