Calibration Security Reset

SHOCK HAZARD Only qualified, service-trained personnel who are aware of the
hazards involved should remove covers. Always disconnect external power.

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:
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
Remove all plastic, foam, vinyl, paper, and other static-generating materials from the immediate work
l
area.

Tools Required

T10 Torx driver - for cover removal
l
Clip leads - for shorting connector pins

Cover Removal

1. Turn off the power. Remove all cables from the instrument.
2. Remove the 6 flat-head screws located on the top and the 7 pan-head screws along the sides (see
