This wrist strap and ground monitor provides effective workstation monitoring in applications with two metal ground requirements. The 773 monitor grounds and monitors two operators and two metal grounds. To improve production yields, the 773 accurately measures ground impedance in automated tools while they are in operation which allows immediate corrective action. Real-time communication and audio alarm allows for immediate shut down should impedance values exceed facility standards. The 773 is miniature in size, easy to install and unobtrusive on the product floor. The monitor’s measurements are ANSI/ESD S6.1 and ANSI/ESD S20.20 compliant.
