PC2R Disassembly/Assembly
Introduction
This chapter contains all the procedures for the disassembly and reassembly for the PC2R—as
well as instruments with factory-installed or after-market options.
Warning: If possible, save all user programs and setups before disassembly. For instructions,
refer to Saving User Data in Chapter 5, page 5-1.
Cables, Connectors
Flat Ribbon Cables
All flat ribbon cables with connectors are keyed, and therefore cannot be reversed. Most flat
ribbon cables have locking cable clips. Be sure to reapply the clips when connecting cables. Flat
ribbon cables that connect to picoflex connectors do not have locking cable clips.
Some flat ribbon cables have exposed wires that insert directly into a wire trap connector. When
disconnecting and connecting these cables, you must look for the marking on the edge of the
cable denoting Pin 1 and be sure that you match it correctly with Pin 1 on the board.
Cable Routing
In some cases, tape secures cable connections or fastens cables to the bottom enclosure. Always
peel back the tape from one side when disconnecting cables so that the tape remains properly
positioned.
