Workstation Monitor

The Model WSM-04 is designed to continuously monitor the connections of ESD wrist strap & work surface. In addition the Instrument results are indicated by the tri color SIGNAL TOWER LAMP.

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. 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.
