🔑Key Features:
-
Multi-Frequency Tone Generation: Emits standard 270Hz, 1kHz, and 2kHz modulated tones, allowing technicians to identify specific fibers in a dense patch panel without breaking the link.
-
Intelligent Backlight Control: Includes an ambient light sensor that adjusts the LCD backlight intensity dynamically. This cuts down on battery drain in brightly lit working environments.
-
Compact Physical Profile: Shares the same ruggedized field casing as the HSV-300P. It weighs 285 grams, measures 200mm x 90mm x 50mm, and runs for roughly 45 hours on three standard AA alkaline batteries.
