FLUKE 77 IV/BN Digital Multimeter

The Fluke Model 77 IV/BN is a 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 againts transients in fixed equipment installation at the distribution level; CAT IV meters are designed to protect against transients from the primary supply level (overheard or underground utility service).

The Meter measures or test the following: 

• AC/DC voltage & current
• Resistance
• Voltage frequency
• Diodes
• Continuity
• Capacitance
