• ATORCH AC 220V 100A Digital Voltage Meters indicator Power Energy Voltmeter Ammeter latest Amps Volt wattmeter tester detector Description Active energy is calculated as: P = U * I * cos, cos represents the flexibility factor, purely resistive lots (such as incandescent, heater, etc) the flexibility element is usually near to 1, inductive and capacitive load load energy ingredient 0-1; therefore purely resistive load check time, P is substantially equal to or near to U I; check inductive or capacitive lots (such as refrigerators, washing machines, televisions, computers, etc) when, P Less than U I As for the explicit quantity to maintain the flexibility element related to strength factor various for every appliance, please demonstrate table prevail Specification Size: 90x54 Apply to energy grid voltage differ 110V-220V Working voltage: 85 ~ 250VAC Test voltage: eighty five ~ 250VAC Rated power: 100A / 20000W Working Frequency: 45-65Hz Measurement accuracy 1 Feature network voltage direct strength supply, no exterior strength supply, measurement precision, large-screen LCD liquid crystal display demonstrate obviously A Function 1 electrical parameter dimension function (voltage, current, lively power, power) 2 overload alarm operate (over power alarm threshold, the backlight and tool flicker tips) 3 The strength alarm threshold preset function (can set up their own energy alarm threshold) The power button clean function five Power-down records storage function 6 Large-screen LCD screen complete demonstrate operate (display voltage, current, energetic power, power) 7 Backlight B demonstrate and key Display Interface Display voltage, current, power, calories parameters from the large-screen LCD screen simultaneously Packing List 1 electronic voltmeter 1pcs（include 100A Current external shunt） 2 Box 1pcs 3 Chinese handbook 1pcs four Current exterior shunt 1pcs Customer feedback
