Maintenance
Preventing ESD
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.
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.
Exterior Inspection
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 performance. 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 Cleaning
Procedure
Interior Inspection
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.

Benchtop Mainframe Removal and Installation Procedures
Mainframe Cover
To remove the mainframe cover, refer to Figure 14 while performing the
following steps (Note that this procedure assumes that the mainframe does not
include any rails for the rackmount option; if it does, remove the rails before
continuing this procedure).
1. Remove the 12 hex drive screws (6 on each side) using a 3/32 Allen wrench.
2. Remove the eight T-7 screws: four on the top front and four on the top rear.

Benchtop Mainframe Removal and Installation Procedures
Complete the following steps to install the mainframe cover (refer to Figure 14
as necessary):
1. Slide the cover over the mainframe.
2. Tilt the rear of the cover in place and then lower the front until the cover
binds slightly (do not force the cover down).

to4in-lbs.
5. Install the remaining 12 screws on the sides of the mainframe.
6. Tighten all screws.
Card Guides
The card guides at the top and bottom of the mainframe are very similar. The
main difference is that the bottom guides include the spring-loaded shutters to
redirect air into the mainframe. The procedure for removing both guides is
identical. Refer to Figure 15 while performing the following steps:
1. Use a small flat blade screwdriver to pry up the tab of the card guide at the
front of the mainframe being careful not to damage the card guide or the
mainframe.
2. Gently pull the card guide forward until it pops out of place.
3. Remove the card guide.
To install the card guides refer to Figure 15 while completing the following
steps:
NOTE. The bottom card guides are replaced as a unit. These guides are not
intended to be disassembled.
1. Slide the card guide towards the rear of the mainframe and allow the front of
the card guide to snap into place.
2. Test the card guides in the mainframe and verify that they do not move.
3. Reinstall the mainframe cover.
