modules
and their components due to electrostatic discharge (ESD).
Static discharge can damage any semiconductor component

this
oscilloscope.
1 . Minimize
handling of static-sensitive modules.
2.
Discharge the static voltage from your body by wearing a grounded
antistatic wrist strap
while handling these modules.
All
service must be
done at a static-free work station.
