Features

AC Outlet Continuous Monitor: Continuously monitors the path-to-ground integrity of the outlet; meets the ANSI/ESD S6.1 requirement for verifying wiring orientation

Visual Common Point Ground Indicator: Identifies a properly wired AC outlet that may be used for grounding purposes of an ESD Control Plan

Visual and Audio Fault Alarms: Alarms instantly when a failure occurs to alert operators and supervisors of a problem

Six Banana Jacks and Six Screws for #8 Ring Terminals: Provides numerous groundable points for wrist straps, mats, carts, tools, and other items. May also be connected to other grounding hubs.

Enclosure with Mounting Tabs: Allows the monitor to be placed away from the AC outlet and in areas of high visibility

Made in the United States of America

Aditional Information

When the Common Point Ground Monitor is plugged into an electrical receptacle, its green LEDs illuminate when both the power outlet's wiring is correct and the path-to-equipment ground via the equipment grounding conductor is intact. The monitor provides 12 verified ground points when in a PASS condition. The monitor's red LEDs illuminate and audible buzzer sounds when either the outlet’s wiring is incorrect or the path-to-equipment ground is defective. Mounting tabs make it suitable to install in workbench or equipment settings.

The outlet ground line is tested by measuring voltage between it and the neutral line. It is normal to have a few volts of AC induced on the neutral line. If the Common Point Ground Monitor measures only a few volts, the ground line to neutral impedance is low and the ground line would make a suitable ESD ground point. If the monitor measures more than just a few volts between ground and neutral, this indicates either that they are not referenced to each other or that the outlet and associated wiring should be checked for loose connections. In this case, the Common Point Ground Monitor will sound a warning alarm and display a red FAIL indication and should not be used for an ESD grounding point until corrected.
