Product Description for "ESD WRIST STRAP MONITOR"
The Model WSM-01E has independent circuitry designed to continuously
monitor the connections to ESD earth
of Wrist strap.
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.
