The 3M WS Aware Workstation Monitor provides continuous monitoring
of all grounding parameters on a workbench or in a tool in full compliance
with ANSI 6.1 and ANSI/ESDA - S20.20 requirements, as well as high-
frequency noise (EMI) on ground. For operators, WS Aware Monitors
utilize dual wrist straps for a continuous resistivity check of human body
connection and patented advanced DSP technology for reliable monitoring
utilizing ultra-low control voltage. Each operator’s body voltage is also
continuously monitored. Patented optional Big Brother terminals allow
the monitor to alarm when an operator approaches static-sensitive
components, but does not plug in his or her wrist strap properly.
WS Aware CTC061 provides continuous monitoring for two metal
grounds (such as tools) and for two “soft” grounds (such as dissipative
mats, surfaces and parts made of dissipative plastics), or four metal
grounds (CTC062). It provides monitoring of EMI on metal grounds with
programmable alarm thresholds. As electromagnetic interference (EMI)
is rapidly becoming a significant factor in equipment failures, this
patented feature helps to provide proper operation of your equipment.
Features
• Highly integrated credit card-size unit offers combination of features.
• Proper operator grounding — Big Brother operator presence detector
• Ultra-low voltage — only 25 millivolts of signal to any part of wrist
• ANSI 6.1 and ESDA S20.20 compliant ground monitoring.
• EMI monitoring on grounds.
• Safety — built-in safety 1 megohm resistors for each half of the wrist strap.
• Output to facility monitoring system.
