Electro-Metric's Electrostatic Discharge (ESD) Simulation products simulate in a known and repeatable way the "static electricity" effects that we have all experienced by walking across a woolen or nylon carpet in the winter time and then touching an object such as a metal door knob or our office word processor table.

The EDS-250 Electrostatic Discharge Simulator consists of the following:

1. Model EDS-250/300 control unit

2. Either/both DC/PD probe


The EDS-300 is designed to simulate furniture and personnel discharge and is capable of direct and indirect voltage discharge ESD testing.Voltage is stored in the EDS-300 vanes, acting as a 150 pF distributed capacitance, and released into an object through the use of probes. The vane geometry was selected for several reasons:

  • It is less sensitive to the presence of nearby capacitive bodies
  • The charge is spread over a larger surface area
  • The vertical edges to which the discharge probe is clamped allow adjustment to different heights without altering the discharge circuit
