Overview
The Fluke 15B MAX is designed for those who need a rugged, reliable, and highly accurate tool for everyday electronics and electrical troubleshooting. Building on the foundation of the 15B+, the MAX version offers improved ergonomics and a much faster continuity test. Its standout feature is the Audible and Visual Input Alert, which warns the user if the test leads are connected to the wrong terminals for the selected measurement—preventing blown fuses and potential equipment damage.
Key Features
Input Alert System: Audible and visual warning if you have leads in the $A/mA$ jack while the dial is set to Voltage.
Large Backlit Display: A significantly larger 6000-count screen with a bright white backlight for clear reading in any environment.
