Handling Precautions For Using Static Sensitive Devices; Disassembly And Reassembly - Fluke 8060A Instruction Manual

5-4. Handling Precautions for Using Static Sensitive
Devices
This instrument contains CMOS components which can
be damaged by static discharge. Static sensitive
components on the main pcb include U3 and U4. The
microcomputer pcb includes one static sensitive
component, U5, the microcomputer. To prevent damage,
take the following precautions when troubleshooting
and/or repairing the instrument:
Perform all work at a static-free work station.
Do not handle components or pcb assemblies by their connectors.
Wear static ground straps.
Use conductive foam to store components.
Remove all plastic, vinyl and styrofoam from the work area.
Use a grounded, temperature-regulated soldering iron.

5-5. Disassembly and Reassembly

The instrument has two pcbs: the main pcb and the microcomputer pcb. To
gain access to the calibration adjustments, the backup fuse, or the LCD, you
have to remove only the top cover. You can also do some troubleshooting
with only the top cover and the top ac shield off. For other troubleshooting
or to gain access to the microcomputer pcb, you have to remove the main
pcb from the case. If you remove the main pcb from the case, you will need
to perform the calibration adjustments. Be sure to heed the notes and
cautions about special handling requirements.
It is not necessary to remove the main pcb from the bottom case in
order to disassemble or reassemble the LCD. However, because the
LCD and the microcomputer require similar special handling, the
disassembly and reassembly procedures are described together.
