WS Aware Dual Workstation Monitors
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
alerts if an operator is within reach of sensitive components but is not
plugged in.
• Ultra-low voltage — only 25 millivolts of signal to any part of wrist
strap at any time.
• 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.

Iron Man Workstation Monitors
3M Iron Man Workstation Monitors measure voltage directly on circuit
boards during assembly. If there is any electrical overstress (EOS) on
a board, the operator is alerted with both visual and audio alarms. The
monitors are small enough to fit on every workbench where assembly
or service occurs.
Simply connect the overvoltage input to any ground plane connection
of the board or to a mat on which the board is placed, with the supplied
alligator connector. When there is a dangerous EOS exposure, the
operator will be instantly alerted. Additionally, the board itself will be
reliably grounded via a 1 megohm resistor inside the monitor.
The 3M Iron Man Plus Workstation Monitor CTC331 adds complete
monitoring of the entire workbench, including wrist strap and dissipative
mat monitoring. The operator is monitored for proper connectivity and for
excessive body voltage. The dissipative or conductive mat is monitored
for its proper connectivity. A unique replacement wrist strap jack does
not require soldering, which helps improve reliability and helps reduce
the cost of ownership.
Features
• Electric overstress monitoring of every board.
• Alarms allow operators to immediately respond to electric overstress.
• Isolation of exposed assemblies.
• Complete workbench coverage.

Workstation Monitor Checker
An easy-to-use, self-contained and portable system to verify the
operation of your workstation monitors.
The Workstation Monitor Checker was designed specifically to verify
the proper operation of your dual wrist strap, workstation and ground
monitors. The Checker simulates the proper resistances and signals
to check for the correct response and verify that the monitors are in
compliance with your facilities specifications.
Although the Checker was designed to work with 3M monitors such as
3M
™
WS Aware, Iron Man Plus, 3M
™
Ground Master and 3M
™
Ground
Man, it can also be used to verify the operation of most other monitors
on the market today.
