This meter can only be used with one-phase AC power. And it can only measure the active power(real power). It doesn't show Apparent power.
This product to monitor the power consumption of your electronics, it can even be hooked up (2 of them) in your electrical box for whole house monitoring.
It can be used as a more precise "watt-meter" by plugging/unplugging/turning on household items.
Wire this meter up in a 20 amp circuit feeding some of your power amps.

1. Please make sure the AC input is Pure Sine Wave.(Municipal electric power is pure sine wave). Please don't use the meter to measure AC power converterd from a DC-AC inverter UNLESS you can make sure the output from your DC-AC inverter is Pure Sine Wave. This is very importatnt.
2. Applied load should not exceed the rated power.
3. Wiring order can not be wrong.
4. This module is suitable for indoor, please do not use outdoor.
