Power: Test range 0~2kW_x000D_ The display format within 1kW is 0.0~999.9W;_x000D_ The display format above 1kW is 1000~2000W._x000D_ 2. Electricity: Test range 0~9999kWh_x000D_ The display format within 10kWh is 0~9999Wh;_x000D_ The display format above 10kWh is 10~9999kWh;_x000D_ 3. Voltage: Test range 6.5~100V_x000D_ Display format 6.50~99.99V_x000D_ 4. Current: Test range 0~20A_x000D_ The display format is 0.00~20.00_x000D_ Button:_x000D_ 1. Control of the backlight_x000D_ The backlight can be turned on or off by short pressing the button, and the poor light state is automatically saved when the power is turned off._x000D_ 2. Reset the battery_x000D_ Step 1: Press and hold the button until the ''CLr'' character is displayed in the power display area, and then release the button;_x000D_ Step 2: At this time, the battery flashes to indicate that the battery is currently reset. If you press the button again for a short time, the power data is cleared and reseted and flashing;_x000D_ Step 3: If there is no pressing operation within 5 seconds, it means that the power data is not reseted and exits the reset state._x000D_ 3. Voltage alarm value setting_x000D_ Step 1: Press and hold the button until the ''SET'' character is displayed in the power display area, and then release the button;_x000D_ Step 2: After entering this state, the current high voltage alarm value is displayed in the voltage area, and the current low voltage alarm value is displayed in the current area, and the lowest digit starts to flash. At this time, you can ''+1'' this digit by short pressing the button. When it is over 3 seconds, it will automatically switch the adjusted bit, from high voltage alarm value to low voltage alarm value, a total of 6 digits, the range of voltage alarm threshold setting is 6.5~99.9V;_x000D_ Step 3: After setting, press and hold the button until the screen displays ''PASS'' character to indicate that the setting is successful and automatically exits the setting state. 1Measuring function of electrical parameters (voltage, current, power, electric quantity). 2Voltage alarm function (over voltage alarm threshold, backlight and power flicker prompt). 3Power button reset function. It is designed to adapt to a poor light situation. 4Power off data saving function, prevents from data losing when the power's off. 5Full display function of large?screen LCD (display voltage, current, power and power at the same time).1.
