The AVO850 has a 50,000-count TFT colour display, a CAT IV 600 V, and a CAT III 1000 V safety rating. It also has data logging, graphing, and Bluetooth connectivity. Compatible with the Megger AVO Multimeter Link app, users can capture, trend, and graph data, share it with their team or monitor systems remotely. The Link app is available on Android and iOS platforms.
The AVO850 measures DC voltage with ±0.05% accuracy up to 500 V DC. It has True-RMS and a LoZ (low impedance) mode and can withstand voltage spikes up to 8.1 kV, protecting against arc flash hazards.
It also includes 4-20 mA process loop measurement with percentage readings, audible and visual continuity tests, diode and semiconductor junction testing, an analogue bar graph, x-y graphing, temperature measurement, and built-in memory.
