10) Normally, five (5) measurements will be sufficient. Average the
measurements for a result. Record all measurements and save the records
for long term monitoring of GeoGauge operation. The values from each
verifier measurement will oscillate up and down a small percentage and the
average stiffness should be used to compare with the expected stiffness. It is
not necessary to verify daily. Weekly or once a month or when questions
about the validity of the stiffness/modulus measurements occur, then the use
of the Verifier Mass is justified.
11) An average stiffness of roughly -8.6 to -9.8 MN/m is expected on the
Verifier Mass. If this is not achieved, contact Humboldt for assistance.
The GeoGauge is built to withstand normal field instrument handling. The
gauge can still be damaged from mishandling and abuse. It cannot be
over-emphasized that proper care and maintenance will give the owner long life
and reliability from the instrument.
