Replacing the CPU PROM & HART PROM
Procedure
Thermo Fisher Scientific LevelPRO Installation Guide
D-3
If you do not have an extraction tool, a small bladed screwdriver or curved
tip tweezers can be used in critical situations. As seen in Figure D–3, two
corners of the PROM socket have slots for the extraction tool. These slots
can be used to extract the PROM using a small bladed screwdriver or
curved tip tweezers (reference Figures D–4 and D–5). Pry up on each of
the two extraction corners a little at a time, going back and forth to extract
the PROM evenly out of the socket.
Caution
Be very careful not to crack or otherwise damage the socket!
