MECHANICAL MAINTENANCE
INSPECTING THE SOURCE ROD
To ensure the integrity of the source rod, Troxler recommends
that a qualified Troxler service person inspect the gauge and the
source rod at least once every five years. This inspection includes
checking for excessive wear, corrosion, or damage that could affect
the safe operation of the gauge.
CLEANING
If the 3430 gauge is to provide precise and accurate measurements
over a long period of time the gauge should be kept as clean as
possible. Monitor the outside surfaces of the instrument for
accumulations of dirt, oil, asphalt, or any other foreign matter. If a
build-up of material is visible on the gauge base or topshell, use the
following procedures for cleaning:
To clean the gauge base, use a putty knife to scrape away any built-
up accumulations of soil or asphalt. Be careful not to damage the
gauge base! After removing any large accumulations, wipe the
gauge base with a cloth soaked in WD-40→. The WD-40 should
remove the remaining debris.
Currently, the 3430 gauge topshell is manufactured from an
engineering thermoplastic designed specifically to provide high
impact strength and to offer excellent compatibility with many
industrial solvents and petrochemicals. The topshell may be cleaned
with mild (low alkaline) soap and water. Other approved cleaning
substances include methyl, isopropyl, or isobutyl alcohols. A cloth
dampened with kerosene or diesel fuel may be used on this topshell
C-10
CAUTION
Personnel should wear a dosimeter to monitor radiation
exposure while performing maintenance on the gauge.
CAUTION
WD-40 can damage the keypad. Do not allow WD-40 to
come in contact with the keypad!
