The Model WSM-01 has independent circuitry designed to
continuously monitor the connections to ESD earth of 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 it 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.
