Digital AC 80-260V 100A 4IN1 Voltage, Current, Power, Energy Meter Wattmeter with Split CT Features: 1. Voltage Test Range: AC 80~260V; Current Test Range: 0~100A; Power Range: 0~22kW; Energy Test Range: 0~9999kWh. 2. It is a compact, lightweight, and functional multimeter, with a large LCD screen, can display voltage, current, active power, and energy simultaneously. It does not control or affect the load in any way. 3. Perfect for working with a generator or solar panel setup, also great for monitoring accumulated energy usage on devices that cycle on and off (refrigerators, dehumidifiers, washing machines, wall-mounted AC units) and phantom loads (cable modems, routers, DVRs). 4. Multifunctional: the accumulated energy can be reset with the button; Store data when power is off; Voltage alarm function (over-voltage alarm threshold, backlight and voltage will flash to alarm). 5. The blue backlight can be turned on/off with the front-accessible recessed switch located on the right side panel.
