The 4640-B will not need much maintenance, but the gauge should
be inspected periodically to ensure precise operation. When
performing maintenance on the gauge, monitor radiation by wearing
a dosimeter.
INSPECTING THE SOURCE ROD
To ensure the integrity of the source rod, Troxler recommends
that a qualified Troxler service person inspect the gauge and
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 THE BASE AND TOP SHELL
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
(see note below). The
WD-40 should remove the remaining debris.
CAUTION
WD-40 can damage the keypad. Do not allow WD-40 to
come in contact with the keypad! The keypad may be
cleaned using a mild soap (such as 409
or Fantastic
),
followed by clean water.
The 4640-B gauge top shell is manufactured from an engineering
thermoplastic designed specifically to provide high impact strength
and offer excellent compatibility with many industrial solvents and
petro-chemicals. The top shell 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 to remove heavy soils.
Avoid prolonged exposure and do not soak.
