Electrostatic discharge (ESD) as low as 60 volts can destroy microwave
diodes. If static discharge is noticed by the operator, it indicates a
voltage of at least 20,000 volts. Materiais conducive to static build-up
Include carpeting, nylon, dry air, paper, adhesive tape, styrofoam, vinyl.
The best method of preventing ESD is for the operator to wear a grounding
strap (HP Part Number 9300-0970) connected to a conductive bench mat
(HP Part Number 9300-0797) that provides a path to ground of between
1 and 2.5 Megohms. Alternatively, the operator can ground himself by
touching any grounding instrument chassis before touching the HP
R85026A board assembly.
