The ARF-200 tester facilitates comprehensive radio signal analysis for ABAX 2 wireless systems. It allows users to check both transmitted and received radio signal strength from ABAX 2 devices at their installed location. The tester offers two modes: measuring the signal received by the tester from the controller, and vice versa. Additionally, it can assess radio noise levels across all four ABAX 2 channels; this noise test can be performed even before system installation. The ARF-200 features LED indicators for signal strength and operating mode, a built-in sounder, and a battery status indicator. It comes with a non-replaceable, built-in battery.
