Product Description

An output voltage port provides a ±2V full-scale analog signal directly proportional to the LCD display reading. For noise-sensitive measurements, the unit can be disconnected from its external supply and powered from its internal batteries. Battery low indicator is activated on the LCD when batteries need recharging via included power supply. Universal power supply includes wall connectors for US, UK, Europe and Australia.
