GEOTECHNICAL INSTRUMENTATION NEWS
The right instrument is built for the
job of monitoring, both in precise
and MRTS measurement with com-
pensators, a robust microprocessor
for performing calculations, an easy
to use interface and the right type of
reflectorless laser for taking fast and
accurate measurements. A sighting
laser is also a very helpful tool for
measuring past obstructions and helps
locate objects close to or blocking line
of sight.
We have determined in this experi-
ment that through parallel using both
the precise and MRTS mode moni-
toring, that when the conditions are
right, we can achieve an accuracy of
+/- 2mm, which is the same as what
we achieve in precise mode. A further
option is to combine the two methods
when taking measurements so that
background noise can be cleared out
further in the field.
