Combo Wrist Strap and Footwear Tester

Model: SCS 770030 

The SCS 770030 is a Combo Wrist Strap and Footwear Tester used to verify that an operator’s personal grounding devices are functioning correctly to prevent electrostatic discharge (ESD). It is a standard tool for personnel grounding verification in anti-static and cleanroom environments.

• Rocker Switch: Allows the user to quickly toggle between "Wrist Strap" and "Footwear" test modes.
• Visual & Audio Alarms: Uses colored lights (Green for pass; Red/Yellow for fail) and an audible buzzer to indicate test results.
• NIST Traceable: Each unit is calibrated to standards traceable to the National Institute of Standards and Technology and typically includes a certificate of calibration.
• Power Options: Operates on a 9V battery or an optional AC power adapter (SCS models 770034 or 770035).

• Wrist Strap Test Limits: 750 kilohms to 10 megohms.
• Footwear Test Limits: 750 kilohms to 100 megohms.
• Test Voltage: 4 VDC.
• Accuracy: ±20%
• Power Requirements: One 9V alkaline battery or an optional AC adapter

• Foot Plate (770032): Required to perform footwear tests; the 770030 unit is often used alone for wrist straps but needs this plate for foot grounders.
