SCS CTC337-WW – Wrist Strap and Ground Dual-Wire Monitor

• System continuously monitors (2) operators and (1) metal tool
• Operator and equipment path-to-ground continuous monitor
• Operator body voltage detection – alert if dangerous voltage to ESD susceptible item is detected
• Digital signal processing technology – small voltage applied when handling sensitive components
• Mini size (0.85in x 2.4in x 2.6in) that uses minimal workspace 

The SCS CTC337 Wrist Strap and Ground Monitor can be used in work areas or other locations to monitor the ground impedance of metal ground connection in process tools including but not limited to semiconductor, disk drive, flat panel and electronic equipment manufacturing environments. Ground impedance monitoring can be used for one metal ground point, such as within a tool. The Wrist Strap and Ground Monitor can be used to monitor the impedance-to-ground and voltage level on two persons wearing dual-wire wrist straps. The unit incorporates green and red LEDs and an audible alarm.

Ground Impedance Monitor – Continuously monitors for ground impedance on one or two separate channels that are connected to one process tool.

Operator Connection – The Wrist Strap and Ground Monitor provide continuous monitoring of operator connected to the monitor via loop resistance check of the operator’s physical presence using a dual wire wrist strap.

Voltage on Person Wrist Strap Monitor – The Wrist Strap and Ground Monitor has one additional feature that allows continuous monitoring for excessive voltage on each operator.

SCS Wrist Strap and Ground Dual-Wire Monitor Features and Attributes:

• Operator and equipment ground continuous monitor – Continuously monitors the path-to-ground integrity of two operators and one metal tool; meets ANSI/ESD S20.20 in accordance with ESD TR1.0-01-01
• Digital signal processing technology – Applies a low test voltage to the operator (0.10V) for the handling of sensitive components
• Operator body voltage detection – alarms if the operator generates or contacts voltage that would be dangerous to an ESD susceptible item
• Miniature Size (0.85in x 2.4in x 2.6in) – Uses minimal workspace and includes mounting tabs for installation underneath table tops
• NIST calibrated with certificate included
• Worldwide power adapter with interchangeable plugs – Works with standard electrical systems in North America, the United Kingdom, Japan, Asia and Europe
• Assembled in the USA with globally sourced materials
