Disassembly
SHOCK HAZARD Only qualified, service-trained personnel who are aware of the haz-
ards involved should remove instrument covers. Always disconnect the power cable
and any external circuits before removing the instrument cover. Some circuits are act-
ive and have power for a short time even when the power switch is turned off.
Electrostatic Discharge (ESD) Precautions
Almost all electrical components can be damaged by electrostatic discharge (ESD) during handling. Component damage
can occur at electrostatic discharge voltages as low as 50 V.
The following guidelines will help prevent ESD damage during service operations:
l Disassemble instruments only in a static-free work area.
l Use a conductive work area to reduce static charges.
l Use a conductive wrist strap to reduce static charge accumulation.
l Minimize handling.
l Keep replacement parts in original static-free packaging.
l Remove all plastic, foam, vinyl, paper, and other static-generating materials from the immediate work area.
Tools required:
l T10 Torx driver (covert disassembly)
l Small flat bladed screwdriver
Cover Disassembly Procedure
1. Turn off the power. Remove all cables from the instrument.
2. Remove the cover screws. Place them in a container so that you do not lose them.
3. Lift off the instrument cover.
