Specification: Working voltage: 80-260VAC Test voltage: 80-260 VAC Maximum power: 100A / 22000W Working frequency: 45-65 Hz Measurement accuracy: class 1 About the function: - Measurement and monitoring of electrical parameters (voltage, current, kWh, watt) - Overload alarm function (alarm threshold above watt, backlight flashing) - Power alarm threshold setting function (you can set your own power alarm threshold) - Power button reset function (kwh) - When turned off, keep data when turned on, continue date - Large LCD screen liquid crystal screen with full display function (voltage, current, kWh, watt) - Backlight function About the display: Display interface. Voltage and current, kWh, watt, electrical parameters on the large LCD screen 1. Watt: measuring range 0-22 kW less than 1 kW: 0.0-999.9W less than 10 kW: 1000-9999W below 22 kW: 10.0-22.0 kW 2. kwh: measuring range 0-9999kwh below 10kWh: 0-9999Wh more than 10kWh: 10-9999kwh 3. Test voltage range 80-260V 80-220V display format. 4. Current test range: 0-100A Display format: 0.00-99.99 A. About the button: - Backlight control you can turn on / off the backlight by pressing briefly - Power reset Step 1: Long press the button (about 5 seconds) until the display flashes, then release the button Step 2: If short press the button again, the power (kwh) will reset to zero and quit flickering Step 3: If long press the button for 5 seconds until it stop flickering, the power (kwh) data will not clear and exit - Set alarm (watt) Step 1: Long press the button until the LCD screen shows “SET CLr”, release the button Step 2: show the alarm value (watts), short press, the value (number) will increase Do not press the button for 3 seconds, the setting will switch to another bit Step 3: Long press the button (about 5 seconds) ----> save the watt threshold value power threshold setting range: 0-22.0 kW 1.
