Maintenance
This chapter provides information and procedures for removing and replacing
components in the TLA7012 Portable Mainframe and the TLA7016 Benchtop
Mainframe.
WARNING. To avoid electric shock, always power off the instrument and
disconnect the power cord before cleaning or servicing the instrument.
Preventing ESD
When performing any service which requires internal access to the instrument,
adhere to the following precautions to avoid damaging internal circuit boards and
their components due to electrostatic discharge (ESD).
CAUTION. Many components within the instrument are susceptible to static
discharge damage.
Service the instrument only in a static-free environment. Observe standard
handling precautions for static-sensitive devices.
1. Minimize handling of static-sensitive circuit boards.
2. Transport and store static-sensitive circuit boards in their static protected
containers or on a metal rail. Label any package that contains static-sensitive
boards.
3. Discharge the static voltage from your body by wearing a grounded antistatic
wrist strap while handling these circuit boards.
4. Nothing capable of generating or holding a static charge should be allowed
on the work station surface.
5. Handle circuit boards by the edges when possible.
6. Do not slide the circuit boards over any surface.
7. Avoid handling circuit boards in areas that have a floor or work-surface
covering capable of generating a static charge.

Maintenance

Inspection and Cleaning
The instrument is inspected mechanically and electrically before shipment. It
should be free of marks or scratches and should meet or exceed all electrical
specifications. To confirm this, inspect for physical damage incurred during
transit. Retain the packaging in case shipment for repair is necessary. If there is
damage or deficiency, contact your local Tektronix representative.
Cleaning procedures consist of exterior and interior cleaning. Periodic cleaning
reduces instrument breakdown and increases reliability. Clean the instrument as
needed, based on your operating environment.
Inspect the outside of the instrument for damage, wear, and missing parts. Use
Table 1 as a guide. Modules that appear to have been dropped or otherwise
abused should be checked thoroughly to verify correct operation and perfor-
mance. Immediately repair defects that could cause personal injury or lead to
further damage to the benchtop controller, expansion module, or the mainframes
that the module plug into.

Exterior Inspection

Maintenance
TLA7000 Series Mainframe Technical Reference Manual 3
Clean the exterior surfaces with a soft dry lint-free cloth, or a soft-bristle brush.
If any dirt remains, use a soft cloth or swab dipped in a 75% isopropyl alcohol
solution. Use a swab to clean narrow spaces around controls and connectors. Do
not use abrasive cleaning compounds.
CAUTION. Avoid getting moisture inside the instrument during exterior cleaning;
use just enough moisture to dampen the cloth or swab.
Use only deionized water when cleaning. Use a 75% isopropyl alcohol solution
as a cleanser and rinse with deionized or distilled water.
Do not use chemical cleaning agents; they may damage the chassis. Avoid
chemicals that contain benzene, toluene, xylene, acetone, or similar solvents.
Remove the module covers to access the inside of the instrument for inspection
and cleaning. Refer to the Removal and Installation Procedures for detailed
information on cover removal. Inspect the internal portions of the modules and
the mainframes for damage and wear using Table 2 as a guide. Defects found
should be repaired immediately.
