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. 3. Voltage alarm value setting Step 1: Press and hold the button until the ''SET'' character is displayed in the power display area, and then release the button; 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 automat Package List 1 x DC Current Voltage Meter 1 x Instruction Manual
