Preparing for the Installation
Unpacking the Stinger MRT
Use the following two simple tests to verify that the wrist strap is functioning
properly:
Measure the resistance between the wrist strap and its grounding plug. Overall
resistance between these two points must be approximately 1Megohm. If it is
not, replace the strap.
Physically examine the strap for visible damage. If you see any damage, replace
the strap.
Remove plastics from your work area
Work areas must be kept clear of common plastics, such as the following items:
Polystyrene packing containers
Clear plastic bags
Plastic drinking cups
Food wrappers
Clear cellophane tape
These types of common plastic materials can carry a static charge that is not easily
discharged to ground and must not make direct contact with modules or any other
solid state components.
Store components properly
Protect modules immediately after removal from a chassis by placing them in their
original factory packing materials. Storage in approved antistatic packaging is
acceptable when factory packaging is unavailable.
