- Page 3 General information on electrostatics General information on electrostatics Nowadays ESD is a problem at many workstations, because modern microelectronics is easily destroyed by the sequels of ESD. Other branches of industry like e.g. telecommunications-, plas- tics-, and explosive material industry are also heavily affected by ESD. ESD causes losses of time as well as high financial losses and can endanger the human health.

- Page 5 Manual Manual Measuring principle The electrostatic field meter is a parametric amplifier. The electric field influences a current proportional to the electrostatic field. The current is amplified and measured with a selective amplifier. No energy is taken from the field over time means. No radioactive matters are used! Application Areas Detection and Control of electrostatic fields resp.
- Page 6 Manual EFM 822 Changing the measurement distance Press «function/on» until the lower line shows „change distance“ (approx. 2 sec). In the upper line the current distance is shown in cm. By pressing «function/on» the distance can be changed in the following order:...
- Page 7 Maintenance Grounding The device has to be grounded properly to measure the amount and the polarity of an electro- static field. For that purpose the device has to be connected to ground by using the grounding jack (4). Grounding the device by a grounded person (e.g. over conductive shoes or wrist strap) touching the grounding jack suffices under most circumstances.
