static charges produced by walking
across substrates such as carpeting,
vinyl floor tile, and sealed concrete. It
can also be used to detect charge
generation on surfaces such as
conductive or dissipative floor tiles and
carpeting. An ESD technician may also
use this tool to verify proper grounding
between a conductive or dissipative floor
surface and a person wearing personal
grounding devices such as foot
grounders. The amount (or size) of the
charge generated will vary from one
human body to another. Other factors
such as humidity, contamination
between the foot and flooring surface, as
well as human body capacitance will
also affect the amount of charge
generated.
Installation and Removal
If the fixture needs to be removed to
allow use of the Field Meter alone, see
Figure 5.
To obtain the desired result, a ground
cord must be installed onto the Field
Meter and attached to a utility or
common ground point.
Method of Operation
In order to obtain the desired test
results, the meter must be properly
grounded as stated in the Installation
and Removal section. Once installed on
the Fieldmeter, the Test Fixture itself is
isolated from the meter case and ground
and should remain that way.
Cradle the Test Fixture in the palm of
your hand. Once the meter is grounded
and you are standing on the substrate to
be tested, simply walk around, shuffle
your feet or raise a foot, to determine if
the combination of footwear and
substrate produces an electrical charge.
If an electrical charge is generated and
induced onto the human body, the Test
Fixture will transfer that charge onto the
Fieldmeter, and the amount of the
charge will be registered. If it is
necessary to record the amount of
charge, you can save the result by
simply pressing the Hold button on the
front of the Fieldmeter, and pressing the
button with an insulated object. This test
can be done regardless of the type of
footwear or substrate combination.
Other items in your ESD Control
Program may also be tested such as
conductive or dissipative chairs. Simply
sit in the chair on the desired substrate
and move the chair back and forth to
determine if the chair and human body
combination produces and electrical
charge.
