Voltage test range: AC 80~260V; Current test range: 0~100A; Power test range: 0~22KW; Energy test range: 0~9999kWh.
Display has great visibility, very bright and clear; the blue backlight can be turned on/off by the front accessible recessed switch located on the right side bezel.
Multifunctional: the accumulated energy can be reset by button; Store data when power off; Power alarm threshold preset function; Overload alarm function (over power alarm threshold, backlight and power will flash to alarm).
