... The Fluke Model 77 Series battery-powered, average responding-rms indicating multimeter (hereafter "the Meter"), with a 6000-count, 3 3/4-digit display, and a bar graph. This meter meets CAT III and CAT IV IEC 61010 standards. The IEC 61010 safety standard defines four measurement categories (CAT I to IV) based on the magnitude of danger from transient impulses. CAT III meters are designed to protect against transients in fixed-equipment installations at the distribution level ...
