SCS 770724 – 724 Plus Workstation Dual-Wire Monitor

• Single workstation continuous monitor for 2 operators and 1 worksurface
• Digital signal processing continuously monitors wrist straps and operator safety
• Compact monitor size (0.85in x 2.4in x 2.6in) occupies minimal space
• Meets ANSI/ESD S20.20 in accordance with ESD TR1.0-01-01
• Operator test voltage – 0.4V 

The SCS 724 Plus Workstation Monitor continuously monitors the path-to-ground integrity and body voltage of two operators, as well as the path-to-ground integrity for one conductive or dissipative work surface. The 724 Plus Workstation Monitor eliminates the need for periodic testing and record-keeping of wrist straps.

The 724 Plus Workstation Monitor is designed with digital signal processing technology for true continuous monitoring (versus pulsed or intermittent) of wrist strap functionality (path-to-ground and presence of two 1-megohm resistors) and operator safety according to accepted industry standards. It is unaffected by capacitance variations from personnel or the environment. Digital signal processing technology uses dual-wire wrist straps to apply a low test voltage of 0.40 V onto the operator for the handling of sensitive components.

The 724 Plus Workstation Monitor features operator body voltage detection. It will alarm if the operator generates or comes in contact with a voltage that would be dangerous to an ESD susceptible item. Each 724 Plus Workstation Monitor is calibrated with accepted procedures and standards traceable to the National Institute of Standards and Technology (NIST) and includes a certificate of calibration.

ANSI/ESD S20.20 section 7.3 states

“Compliance verification records shall be established and maintained to provide evidence of conformity to the technical requirements.”

Per ANSI/ESD S1.1 Annex A.3 Daily (wrist strap system) testing may be omitted if constant monitoring is used.

Per ESD Handbook ESD TR 20.20 section 5.3.2.4.4

“Typical Test programs recommend that wrist straps that are used daily should be tested daily. However, if the products that are being produced are of such value that knowledge of a continuous, reliable ground is needed, and then continuous monitoring should be considered or even required.”

SCS 724 Plus Workstation Monitor Features and Attributes:

• Single workstation continuous monitor – Meets ANSI/ESD S20.20 in accordance with ESD TR1.0-01-01
• Continuously monitors 2 operator dual-wire wrist straps and 1 worksurface mat
• Digital signal processing technology – Provides stable continuous monitoring (versus pulsed or intermittent) of the wrist strap’s path-to-ground and the presence of its 1 megohm safety resistor
• Operator body voltage detection – Alarms if the operator generates or comes in contact with a voltage that would be dangerous to an ESD susceptible item
• 0.40V Operator test voltage – Reduces the risk of electrical overstress (EOS) for the handling of sensitive components
• 500 millisecond alarm response time – Identifies failures and intermittencies that inferior technologies miss
• Operator remote disconnect alarm – Prevents tampering should one intentionally disconnect the operator remote from the monitor
• Miniature monitor size (0.85in x 2.4in x 2.6in) – Occupies minimal space and includes mounting tabs to secure installations
• Dedicated monitor ground cord – Allows the monitor to be bonded to a reliable ESD ground, AC equipment ground, or auxiliary ground
• Use with dual-wire straps
• 100-240V AC Power adapter with interchangeable plugs – Works with standard electrical systems in North America, the United Kingdom, Japan, Asia, and Europe
• Calibration verification – Use the SCS 770734 Verification Tester to check the test limits of 724 Plus Workstation Monitors without removing them from their workstations
• NIST calibrated with certificate included
• Made in the USA
