The following procedures should be performed to keep the
Model 3440 gauge in good working order. If a serious problem
with the gauge arises, contact the nearest Troxler Service Center
or representative for instructions.
For a list of Troxler and authorized Troxler service centers, refer
to the front of this manual or visit the Troxler website at
CAUTION
Personnel should wear a dosimeter to monitor
radiation exposure while performing maintenance on
the gauge if it is required by their radioactive materials
license or local regulations.

Do not separate the control unit from the base. Doing
so will result in non-compliance with EMC directive. Call
your Troxler representative for additional information.
Cleaning the Base and Topshell
If the Model 3440 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
BindOff, WD-40 or similar non-corrosive cleaner to remove the
remaining debris.
