• ATORCH AC 220V 100A Digital Voltage Meters indicator Power Energy Voltmeter Ammeter latest Amps Volt wattmeter tester detector Description Active power is calculated as: P = U * I * cos, cos represents the ability factor, purely resistive plenty (such as incandescent, heater, etc) the power element is mostly close to 1, inductive and capacitive load load energy ingredient 0-1; therefore purely resistive load check time, P is substantially equivalent to or near to U I; examine inductive or capacitive loads (such as refrigerators, washing machines, televisions, computers, etc) when, P Less than U I As for the explicit number to keep the ability ingredient related to power factor various for every appliance, please show table be triumphant Specification Size: 90x54 Apply to strength grid voltage vary 110V-220V Working voltage: eighty five ~ 250VAC Test voltage: 85 ~ 250VAC Rated power: 100A / 20000W Working Frequency: 45-65Hz Measurement accuracy 1 Feature community voltage direct power supply, no external strength supply, size precision, large-screen LCD liquid crystal display screen display obviously A Function 1 electric parameter size function (voltage, current, lively power, power) 2 overload alarm function (over power alarm threshold, the backlight and tool flicker tips) 3 The energy alarm threshold preset function (can set up their own strength alarm threshold) The energy button clear operate 5 Power-down records garage operate 6 Large-screen LCD display screen full show function (display voltage, current, lively power, power) 7 Backlight B reveal and key Display Interface Display voltage, current, power, calories parameters from the large-screen LCD screen simultaneously Packing List 1 digital voltmeter 1pcs（include 100A Current external shunt） 2 Box 1pcs 3 Chinese guide 1pcs four Current exterior shunt 1pcs Customer suggestions
