Features:1. Voltage test range: AC 80 260V; current test range: 0 100 100a; power test range: 0 2222kw; energy test range: 0 9999kWh.2. Multi-function: reset stored energy by button; store data when closed; voltage alarm function3. It is a compact, lightweight, full-featured multimeter with a large LCD display that can simultaneously display voltage, current, active power and electrical energy.4. Great for use with generators or solar panels, and also for monitoring accumulated energy usage in devices that are turned on and off and apparition loads5. Over-voltage, backlight and voltage alarm thresholds will flash the alarm. It will not control or affect the load in any way.Specification:Power Test Range: 0-22kWWithin 1kW, the display form is 0.0-999.9W1kW and above, the display form is 1000-9999W10kW and above, the display form is 10.0-22.0kWEnergy Test Range: 0-9999kWhWithin 10kWh, the display form is 0-9999Wh10kWh and above, the display form is 10-9999kWhVoltage Test Range: 80-260V, Display Form: 80-220VCurrent Test Range: 0-100A, Display Form: 0.00-99.99AWorking Voltage: 80-260VACTest Voltage: 80-260VACRated Power: 100A/22000WWorking Frequency: 45-65HzMeasurement Accuracy: 1.0Product Size: Approx. 9x5x2.5cm / 3.5x2x1inNotice:1.
