Corrective Maintenance
Corrective maintenance deals with obtaining replacement parts, torque specifica-
tions, and component replacement.
Replacement parts are available from or through the local Tektronix, Inc., field
office or representative.
When ordering parts be sure to include the following information in your order:
1. Instrument type (and option numbers, if any).
2. Instrument serial number.
3. Description of the part, as it appears in the electrical or mechanical parts list.
4. The Tektronix part number.
If a part that has been ordered is replaced with a new or improved part, the local
Tektronix field office or representative will contact you concerning any change in
the part number. After repair, the circuits may need readjustment.
Only #4 screws are used in the PATHFINDER to secure the case halves together.
DO NOT USE MORE THAN 3 INCH POUNDS OF TORQUE ON THESE
SCREWS.
Replacing Assemblies
WARNING.
Disconnect the AC adapter and batteries before replacing any
components.
Follow this procedure to remove and replace the back cover of the PATHFIND-
ER:
1. Remove the four screws securing the back cover to the front cover.
2. Gently separate the back cover about 1 inch from the PATHFINDER, taking
care to not pull the rear panel (connector panel) away with it.
3. Disconnect the battery cable from J10. Make sure to pull on the connector
housing to do this, not the wires. The back cover is now free and may be
moved away from the instrument.
4. Replacement is the reverse of removal.
