It may also be important to update firmware on the Minimus - refer to

Caution: Although the Fortis is a strong motion instrument, it contains
sensitive mechanical components which can be damaged by
mishandling. If you are at all unsure about the handling or installation of
the device, you should contact Güralp Systems for assistance.
The Fortis is ideal for monitoring vibrations at field sites. Dig a
shallow pit, make a smooth base, level the sensor and then cover
with a box or bucket, bringing the cable out from under the
bottom. The pit can be covered and back-filled with soil, sand, or
polystyrene beads.
