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. For more information about the difference, please search AC POWER on wikipedia. • Working voltage: 80 ~ 260VAC • Working frequency: 50/60Hz • Measuring:Accuracy: • Power Consumption: 0.2W • Measurement speed: 2 times/s • Stores data when power off • The blue backlight can be turned on/off manually Test Range and Display format 1.Power: test range: 0~22kW • • 1kW~10kW, display: 1000~9999W • > 10kW, display: 0.1~22.0kW 2.Energy: test range: 0~9999kWh • • >10kWh, display: 10~9999kWh 3.Voltage: test range: 80~260V(single-phase) • Display: 80~260V 4.Current: test range: 0~100A • Display: 0.00~99.99A Precautions • Please make sure the AC input is Pure Sine Wave.(Municipal electric power is pure sine wave). This is very importatnt. • 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. • Applied load should not exceed the rated power. • Wiring order can not be wrong. Review the wiring diagram for installation • This module is suitable for indoor only. Please do not use outdoor.
