Features Current Function: Measuring function of electrical parameters (voltage, current, power, electric quantity). Voltage Alarm Function: Voltage alarm function (over voltage alarm threshold, backlight and power flicker prompt). Power Button Reset Function: Power button reset function. It is designed to adapt to a poor light situation. Power Off Data Storage: Power off data saving function, prevents from data losing when the power's off. LCD Full Display: Full display function of large-screen LCD (display voltage, current, power and power at the same time). Specification: Item Type: DC Current Voltage Meter Material: ABS Working Voltage: 6.5~100VDC Test Voltage: 6.5~100VDCRated Power: 20A / 2000W Measurement Accuracy: Level 1.0 Display and Button Display Interface:The large LCD screen displays the voltage, current, power and power parameters simultaneously. Display Format: 1. Power: Test range 0~2kW The display format within 1kW is 0.0~999.9W; The display format above 1kW is 1000~2000W. 2. Electricity: Test range 0~9999kWh The display format within 10kWh is 0~9999Wh; The display format above 10kWh is 10~9999kWh; 3. Voltage: Test range 6.5~100V Display format 6.50~99.99V 4. Current: Test range 0~20A The display format is 0.00~20.00 Button: 1. Control of the backlight 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. 2. Reset the battery Step 1: Press and hold the button until the ''CLr'' character is displayed in the power display area, and then release the button; 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; 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.
