ESD Station Monitor
CONTINUOUS WORK STATION MONITOR (Model: WSM-01)
The Model WSM-01 is designed to continuously monitor the connections of
ESD wrist strap & work surface. WRIST STRAP: This section
continuously monitors the wrist strap to detect loss of continuity
between operator and monitor. Conditions such as broken coils cords and
improper contact with the skin are detected instantly to alert the
operator before serious and expensive ESD damage can occur. As there is
no resistance return path from the wrist strap, it uses the capacitive
AC pulse principle to check if the operator is adequately grounded.
The wrist strap section is automatically activated when wrist strap is
plugged in. continuous monitoring reduces the need for periodic checks
and also ensures greater security. ESD WORK SURFACE: The work surface
is monitored by a DC Resistive principle and a warning is given in case
the surface to ground resistance exceeds the safe threshold value of 10
Meg ohms.

CONTINUOUS WORK STATION MONITOR (Model: WSM-02)
The Model WSM-02 is designed for continuously monitor the connections
of two ESD wrist strap & work surface. WRIST STRAP: two-wrist strap
sections continuously monitor the wrist strap to detect loss of
continuity between operators and monitor. Conditions such as broken
coils cords and improper contact with the skin are detected instantly
to alert the operator before serious and
expensive ESD damage can occur. As there is no resistance return path
from the wrist strap, it uses the capacitive AC pulse principle to
check if the operators are adequately connected to the instrument. The
wrist strap sections are automatically activated when wrist straps are
plugged in. continuous monitoring reduces the need for periodic checks
and also ensures greater security.

CONTINUOUS WRIST STRAP MONITOR (Model: WSM-03)
Wrist Straps are the first line of defense against electrostatic charge
build-up on the human body. They are designed to carry away this charge
as soon as it is generated.
This model WSM-03 continuously monitors the wrist strap to detect loss
of continuity between operator and monitor. Conditions such as broken
coil cords and improper contact with the skin are detected instantly to
alert the operator before serious and expensive ESD damage can occur.
As there is no resistive return path from the wrist strap, it uses the
Capacitive AC pulse principle to check if the operator is adequately
grounded. The system is automatically activated when the wrist strap is
plugged in. Continuous monitoring reduces the need for periodic checks
and audits and also ensures greater security.

ESD EVENT MONITOR (Model: EED-01)
The ESD Event Monitor is a portable, battery-operated instrument,
incorporating the latest digital technology, to indicate the presence
of approaching static electricity. It is designed to provide a quick
and convenient method of locating static charges without any polarity.
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.
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 antenna 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.
