SATEL ARF-100 is radio signal level tester for two-way wireless ABAX systems, designed to work together with the ACU-100 wireless system controller (with firmware version 1.05 or later). The tester enables checking the level of radio signal received either by the controller from the tester, or by the tester from the controller. This way it facilitates the selection of suitable installation locations for the wireless components of the ABAX systems. The radio signal level indicator consists of 7 LEDs (2 yellow and 5 green) with percentage markings. The red LED below shows the operation mode of the tester (the direction of the transmission). Another LED below (the lower one) indicates the type of power supply of a wireless device simulated by the tester (from 3 V lithium battery or external power source).
