Feature:1. COLOR LCD DISPLAY: The multimeter features a vibrant color LCD screen that allows for clear visibility even in bright sunlight or dark environments. The large font design makes it easy to read data, making it particularly convenient for middle aged and elderly electricians.2. AUTO RECOGNITION: The multimeter automatically selects the appropriate mode for measurement, eliminating the need for manual mode switching and reducing any delays. It intelligently detects and measures both AC and DC current, AC and DC voltage, resistance, and continuity. When inserted into the amplifier jack, it automatically switches to AC DC current mode.3. MULTI FUNCTION DESIGN: This multimeter is packed with a wide array of functions, including measurement of AC DC voltage, AC DC current, resistance, capacitance, diode testing, switch testing, frequency, and non contact infrared temperature measurement. It supports 9999 count true RMS, NCV non contact measurement, live wire detection, V alert AC voltage sensing with buzzer alarm, auto power off, and built in night illumination.4. HIGH VOLTAGE DIODE FUNCTION: Multimeter supports diode testing, with an LED that lights up for diodes under 16V. It covers testing for rectifier diodes, regulator diodes, and LED diodes, among others, with a maximum test voltage of approximately 16V.5. INFRARED TEMPERATURE MEASUREMENT: The meter shows real time temperature and the highest recorded temperature. Throughout the scanning process, the highest temperature value recorded will always be displayed on the screen.6. POWER SUPPLY SYSTEM: This multimeter features a dual mode power supply system, supporting either a built in 3.7V lithium battery or two AAA alkaline batteries (not included) for various power supply needs. The multimeter prioritizes the use of the lithium battery and automatically switches to the alkaline battery power supply when the lithium battery is depleted.7. WIDE APPLICATIONS: This multimeter finds extensive usage in electrical testing, electrician work, electronic repairs, LED industry, automobile maintenance, and other related industries.Specification:Item Type: Digital MultimeterMaterial: ABSDisplay: Color LCDMaximum Displayed Value: 9999 digitsPower Supply: Built in 3.7v lithium battery 1200mAh (included), and support for additional installation of 2 AAA alkaline batteries (not included).Package List:1 x Multimeter 2 x Test Pen 1 x USB Cable 1 x Screwdriver 1 x Manual 1 x Storage Bag
