2.
Place the cover plate over the welded bolts.
3.
Install washers, then nuts. Avoid excessive force while tightening the cover
retaining nuts, as this will distort the underlying steel surface and can give
rise to spurious strain readings.

3.3 CABLE AND CONNECTOR PROTECTION
The cable should be protected from accidental damage caused by moving
equipment or fly rock. This is best accomplished by putting the cable inside
flexible conduit and positioning the conduit in as safe a place as possible.
(Flexible conduit is available from
conduit bulkhead connectors to the cover plates. (The
stamped knockout which, when removed, provides a hole for connecting the
conduit connector.)
3.4 PROTECTION FROM CORROSION
It is imperative that installation weld points, if any, be protected from corrosion.
Stainless steel instruments will not corrode, but the substrate can corrode,
especially at weld points, unless they are covered by a waterproofing layer.
recommends you follow this procedure:
GEOKON
1.
Apply several drops of cyanoacrylate adhesive to the edge of all spot
welded mounting tabs. The glue will wick into the gap between the
mounting tabs and the substrate and provide the first line of defense.
2.
Mask off the areas where spot welds are needed.
3.
Spray self-etching primer (available locally) over mounting tab areas and all
exposed bare metal areas. The idea is to protect substrate weld points. It is
important to completely cover mounting tab edges, paying attention to
where the tab is under the instrument. Be sure to spray beneath the coil
housing, if applicable; do not worry if the primer also coats the instrument.
