Installation Site
When choosing a site, account should be taken of ease of access and risk of damage or loss of
monitoring equipment.
The following locations should be avoided, wherever possible:
areas where voids could affect the monitoring results, e.g. a hollow area beneath a
concrete pavement; and
areas where loose or poorly compacted fill could affect the monitoring results, e.g. on the
berm of a slope, or close to concrete steps or surface drainage channels
DO NOT place iVIBE on a loose paving slab for this may move independently, giving rise to higher
readings than those to which the adjacent structure is being subjected.
DO NOT place a brick, or similar heavy object, on top of the iVIBE. There is a very strong chance
that it will lead to higher readings. Its centre of gravity will be raised and the object may well
move independently of iVIBE giving spurious readings.
DO NOT drop the microphone. This is a precision item and must be handled carefully.
DO NOT drop the iVIBE seismic body. Damage to the accelerometers could be the result.
DO prevent iVIBE from being knocked or disturbed by objects, people or animals and thus
giving false readings.
DO check daily that equipment has not been disturbed.
When using iVIBE to monitor vibration only, the instructions regarding the tripod and
microphone placement may be ignored.
