2.2 Electrostatic Discharge (ESD)
Handling Procedure
Magnetrol’s electronic instruments are manufactured to the
highest quality standards. These instruments use electronic
components that may be damaged by static electricity pre-
sent in most work environments.
The following steps are recommended to reduce the risk of
component failure due to electrostatic discharge.
• Ship and store circuit boards in anti-static bags. If an
anti-static bag is not available, wrap the board in aluminum
foil. Do not place boards on foam packing materials.
• Use a grounding wrist strap when installing and removing
circuit boards. A grounded workstation is recommended.
• Handle circuit boards only by the edges. Do not touch
components or connector pins.
• Make sure that all electrical connections are completely
secure and none are partial or floating. Ground all equip-
ment to a good, earth ground.
