TLA5000 Series Service Manual
WARNING. To avoid electric shock, always power off the instrument and
disconnect the power cord before cleaning or servicing the instrument.
Inspection and Cleaning
The logic analyzer 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 the chassis 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 of the chassis.
Clean the chassis as needed, based on the operating environment.
Use a dry, low-velocity stream of air to clean the interior of the chassis. Use a
soft-bristle, nonstatic-producing brush for cleaning around components. If you
must use a liquid for minor interior cleaning, use a 75% isopropyl alcohol
solution and rinse with deionized water.
Clean the exterior surfaces of the chassis with a dry lint-free cloth or a soft-
bristle brush. If any dirt remains, use a 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 compounds on any part of the chassis that may
damage the chassis.
Clean the On/Standby switch using a dampened cleaning towel. Do not spray or
wet the switch directly.
CAUTION. Avoid getting moisture inside the instrument during exterior cleaning;
use just enough moisture to dampen the cloth or swab.
Do not wash the front-panel On/Standby switch. Cover the switch while washing
the instrument.
Use only deionized or distilled 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.
