This file is the user manual for HL-RC wireless data logger. It introduces the product features, installation, operation, maintenance, etc.
This manual provides instructions for the Rotronic HL-RC series of wireless data loggers, which measure humidity and temperature with high precision. The devices save measurements internally and transmit data to the ROTRONIC HW4 software via LAN interfaces or USB dongles on frequencies of 433.92 MHz (Europe) or 915 MHz (USA). The guide covers two versions: devices with integrated battery power monitors (HL Types) and those without (LOG Types), noting that these versions are not compatible with each other.
