The EC-2V is used to record voltage on two channels, Live (Hot) with respect to Neutral and Earth (Ground) wrt Neutral, if you suspect Earth/Grounding issues then the EC-2V would tell you if the local Neutral is developing a voltage wrt the local Earth. Voltage optimisation companies also use the product to monitor voltage levels pre and post optimisation. Many power distribution companies use the product to highlight real voltage problems.
