The Electrostatic AlarmZ201is a portable, battery-operated instrument, incorporating the latest technology, to indicate the presence of approaching static electricity. It is designed to provide a quick and convenient method of locating static charges and their approximate charge levels. It is primarily intended for use in static-safe handling areas, as an early warning system to alert the personnel nearby.

The hazard may be in the form of personnel who are generating static or personnel who may be holding a charged object without observing the standard safety procedures for handling static sensitive devices.

The instrument incorporates a unique self-resetting feature and therefore requires no manual adjustments or zeroing. It can be kept 'ON' for continuous monitoring of critical static-safe areas, thanks to its remarkably low current drain of only 1 ma.

THEORY OF OPERATION
A static charge on any object produces an electric field whose strength is an inverse function of the distance from the charge. A given magnitude of charge always produces a given field strength at a given distance.

The unique sensor of the instrument actually responds to this electric field. However, more specifically, it senses only changes in the electric field, so to detect a charge there should be relative motion between the instrument and the charged body.

As per ANSI/ESD S20:20 all conductors including Personnel must be electrically connected and attached to a known ground.
A common question aboutanti-static wrist strapsis how and where to ground them. Anti-static work station operators need a convenient method of grounding their wrist straps where the ground cord wont get in the way of their work.This convenient deviceprovides the means to ground anti-static wrist straps at your work station.
The strong bracket mounts (with just 2 screws) to the bottom front edge of your work table or bench. Two banana sockets located in the front of the bracket allow for easy connection of two wrist strap cords (for operators working side by side).

• Designed to mount under bench, saving work surface space
• banana jacks allow for grounding two anti-static wrist straps at once
• Lug for attachment to earth ground
• Front edge bench mounting of ground block via two screw slots

This instrument is designed to detect the level of Static Charges present on a human body and allow access into an ESD safe area provided the Body Static voltage is under 100V.

It is very simple to use and only requires the personnel to Press & Hold the Test Button on the instrument. If the Body voltage is under 100V, the Green PASS Led will light and the magnetic lock is deactivated for a few seconds thereby allowing access through a door or turnstile.

The personnel should normally be free of Static Voltage provided proper ESD protection measures have been taken. Therefore, it also serves to verify whether the measures taken to make a particular area ESD safe are effective. By such measures we mean conductive flooring, ESD wrist straps & Footwear, ionizing equipment, etc.

This is designed to safely drain away any static charges present on a Human body before entering an ESD safe area. A 1 megohm resistor is provided in the ground cord as precaution against risk of shock.

Ground the stand to a suitable ESD ground point by means of the cord.

Stand on the Base Plate while wearing the Conductive / Static Dissipative Footwear and also touch the top plate. Any static present on the body will get drained away.
