3.6 Electrostatic Discharge
Precautions should be taken to prevent damage to devices by electrostatic discharge. Static charge tends to
accumulate on insulated surfaces such as synthetic fabrics or carpeting, plastic sheets, trays, foam, tubes or
bags, and on ungrounded electrical tools or appliances. The problem is much worse in a dry atmosphere.
In general, it is recommended that individuals take the precaution of touching a known ground before
handling devices. More often, handling equipment that is not properly grounded, causes damage to parts.
Ensure that all plastic parts of the tester, that are near the device, are conductive and connected to ground.
