100A AC 80~260V Digital Power Meter Monitor Voltage KWh Watt Voltmeter Ammeter Specification: The working voltage: 80-260VAC Test voltage: 80-260VAC Max power: 100A/22000W Working frequency: 45-65Hz The measurement precision: Class 1 About Function: - Measurement and monitor the electrical parameters(voltage, current, kwh, watt) - Overload alarm function(more than watt alarm threshold, backlight flashing) - Power alarm threshold preset function(can set up their own power alarm threshold) - Power(kwh)button reset function - When power off ,store the data, when on ,continue the date - Large screen LCD liquid crystal screen full display function(voltage, current ,kwh,watt) - Backlight function About Display: Display interface. By the large screen LCD display LCD monitor voltage and current,kwh,watt,electric parameters 1. Watt: the measurement range of 0-22kW less than 1kW: 0.0-999.9W less than 10kW: 1000-9999W less than 22kW: 10.0-22.0kW 2. kwh: the measurement range of 0-9999kwh less than 10kWh:0-9999Wh more than 10kWh:10-9999kwh 3. The test voltage range of 80-260V Display format 80-220V 4. Current test range:0-100A Display format: 0.00-99.99A About Button: - Backlight control can turn on/off backlight by short press - Power reset Step 1: long press the button (about 5 seconds),til display flicker, then release the button Step 2:if short time press the button again, the power(kwh)reset zero and exit flicker Step 3:if long time press button for 5 seconds until it is no longer flicker, power(kwh)data is not cleared and exit - Set the alarm(watt) Step 1: long press the button, till the LCD screen display "SET CLr",release the button Step 2: show the alarm (watt)value,short time press, value (number)increase don't press the button for 3 seconds, the setting switch to other bit Step 3: long time press the button(about 5 seconds)---->save the threshold watt value threshold setting watt range:0-22.0kW Notices: 1. Suitable for indoor ,not outdoor 2. Should not exceed te rated power 3. Wiring can not be wrong 4. The tape' color of the CT will be random   Package Includes: 1 x AC 100A Power Meters Monitor Volt Amp kWh Watt Digital Cambo Meter with case 1 x CT
